Description

Top rule

XL C/C++ for Linux, V13.1.6 and XL Fortran for Linux, V15.1.6 continue to deliver additional functionality and enhancements that include support for the latest IBM POWER9 technology. These features are designed to improve application performance and capability.

Exploitation of the new POWER9 technology

With XL C/C++ for Linux, V13.1.6 and XL Fortran for Linux, V15.1.6 compiler support now includes exploitation of the POWER9 architecture.

  • New architecture and tune compiler options for POWER9 technology

    The -qarch compiler option specifies the processor architecture for which code is generated. The -qtune compiler option tunes instruction selection, scheduling, and other architecture-dependent performance enhancements to run best on a specific hardware architecture. With this new release of XL C/C++ for Linux, V13.1.6 and XL Fortran for Linux, V15.1.6, new architecture and tune compiler suboptions are made available to specify code generation explicitly for the POWER9 architecture. The compiler option -qarch=pwr9 instructs the compiler to produce code that can fully exploit the POWER9 architecture. The compiler option -qtune=pwr9 enables optimizations specifically for the POWER9 architecture.

    Compiling your application with the new -qarch=pwr9 and -qtune=pwr9 compiler options allow you to automatically exploit the new capabilities in the POWER9 architecture without having to rewrite your code.

    The existing -qarch=pwr8 now generates code that executes on both the POWER8® and POWER9 architectures. The existing -qtune=balance allows for balanced tuning for both POWER8 and POWER9.

  • Built-in and intrinsic compiler functions for POWER9 technology

    A number of new built-in functions and instrinsic functions are delivered in these releases to unlock POWER9 architecture instructions. They enable you to have direct access to POWER9 features at the application level.

  • Mathematical Acceleration Subsystem (MASS) Library enhancements

    The MASS libraries are an accelerated set of frequently used mathematical functions that provide improved performance over the corresponding standard system library functions. The highly tuned MASS libraries are enhanced to support the POWER9 technology.

Support for additional features of OpenMP 4.5

OpenMP provides a high-level, directive-based API to parallelize applications. OpenMP is higher level programming model that allows for increased programmer productivity. Implementing your application with OpenMP provides source code that is portable across multiple architectures and platforms.

GPU support within OpenMP was initially delivered in XL C/C++ for Linux, V13.1.5 and XL Fortran for Linux, V15.1.5. Code is optimized for both the POWER® CPU and the NVIDIA GPU. In this release, the OpenMP support is enhanced with additional features for offloading function and associated data to the GPU and also providing additional performance:

  • New directives include:
    • omp simd (SIMD for XL Fortran), which is applied to a loop to indicate that multiple iterations of the loop, can be executed concurrently by using SIMD instructions
    • omp distribute simd (DISTRIBUTE SIMD for XL Fortran) directive that distributes loop iterations to each master thread and then executes each set of distributed iterations concurrently by using SIMD instructions.
  • Updated directives include:
    • omp target (TARGET for XL Fortran), the _ptr device clause that is newly supported on the omp target directive. omp target is_device_ptr( list ) indicates that the data variables in list are device pointers that exist within the device data environment
    • omp target data(TARGET DATA for XL Fortran) the use_device_ptr clause that is newly supported on the omp target data directive. omp target data use_device_ptr( list ) converts the data variables in list into device pointers to the corresponding variables in the device data environment
  • OpenMP 4.5 with support for features, such as device constructs, data mapping, SIMD, and TARGET, can be used to help offload compute-intensive parts of applications and associated data to the NVIDIA GPU (graphic processing unit) that comes with a number of POWER servers. -qsmp=omp enables support for OpenMP and -qoffload instructs the compiler to offload OpenMP 4.5 target regions to an NVIDIA GPU.

The NVIDIA CUDA Toolkit v9 for POWER9 is required during the compilation and linking process. CUDA Toolkit v9 for POWER9 is available from NVIDIA.

CUDA Fortran

CUDA Fortran support was initially delivered in XL Fortran for Linux, V15.1.4 to provide the CUDA Fortran programming model to access and exploit the NVIDIA GPU accelerator. CUDA Fortran was enhanced and refreshed in XL Fortan for Linux, V15.1.5. Now, XL Fortran for Linux, V15.1.6 delivers the following CUDA Fortran enhancements:

  • Support for shuffle intrinsics
  • Support for the cudaMemAdvise, cudaMemPrefetchAsync, cudaDeviceGetStreamPriorityRange, cudaStreamCreateWithPriority, and cudaStreamGetPriority runtime API functions
  • Improved performance for kernels that have assumed shape, allocatable, or pointer dummy arguments
  • Configuration of GPU stack and data limits by using the XLCUF_GPU_STACK_LIMIT and XLCUF_GPU_HEAP_LIMIT environment variables
  • Display of GPU stack and data limits by using the XLCUF_DISPLAY_LIMITS environment variable

OpenMP interoperability with CUDA C/C++ and CUDA Fortran

XL C/C++ for Linux, V13.1.6 and XL Fortran for Linux, V15.1.6 provide support for OpenMP interoperability with CUDA C/C++ and CUDA Fortran. With this support you can enhance your OpenMP functionality with existing implementations of CUDA C/C++ or CUDA Fortran. Programming with OpenMP, CUDA C/C++, and CUDA Fortran enables you to develop more portable applications while providing you the opportunity to tune for optimal performance. You can quickly extend your existing CUDA applications. With this feature you can:

  • Call kernels that are written in CUDA C/C++ or CUDA Fortran in your OpenMP programs from the host.
  • Use the OpenMP USE_DEVICE_PTR clause to pass OpenMP mapped variables to CUDA kernels that are launched from the host.
  • Use the OpenMP IS_DEVICE_PTR clause to access CUDA device attribute variables or to pass device addresses directly to target regions.

Debugging support

XL C/C++ for Linux, V13.1.6 and XL Fortran for Linux, V15.1.6 provide the following debugging enhancements:

  • You can use the -gsplit-dwarf option to enable the DWARF debugging information to be generated in a separate .dwo file. You can associate this file with your DWARF consuming debugger to debug your application. You no longer have to include the debug information with each of you applications. The .dwo file can also be used with DWARF consuming profilers.
  • You can compile with -O2 -g8 to get debug at opt support for inlined functions. For example, stopping, showing call stack, and showing parameter and local variables are supported. This feature can help you with debugging optimized code. This feature is only available with XL C/C++ for Linux, v13.1.6.

Product positioning

Top rule

With XL C/C++ for Linux, V13.1.6 (on little endian distributions) and XL Fortran for Linux, V15.1.6 (on little endian distributions), you can create or port applications for execution on the latest POWER9 architecture. The POWER9 architecture supports the little endian architecture, and is designed to handle big data and to drive modern workloads for cloud, mobile, and social environments.

Ability to unleash the full power of IBM processors

At a basic level, compilers are a bridge between your applications and the hardware architectures on which you run your business. IBM compilers are designed to unleash the full power of IBM processors, which include those for the different architectures that are shipped in the popular Power Systems. IBM compilers exploit the POWER9 technology.

IBM compilers are designed to improve programmer productivity. The advanced compilation technology enables programmers to exploit leading-edge performance of new hardware without source code changes. Developers only need to focus on the business logic of the applications and let the compiler figure out the best way to transform and optimize the code generation for the systems the application will run on.

Powerful, no-hassle performance optimization

Well written and thoroughly debugged code, which is fully conformant to its language standard, can take maximum advantage of the optimizing technology in XL C/C++ and XL Fortran, which may provide an increase in performance. The optimization and hardware features in XL C/C++ and XL Fortran help improve developer productivity. These compilers can generate code that exploits the leading-edge performance in existing and new hardware, often with minimal or no source code changes.

XL C/C++ and XL Fortran support several levels of increasingly, aggressive code transformations. Advanced optimization techniques, such as inter-procedural analysis (IPA) and profile-directed feedback (PDF), are available only at high levels of optimization but can result in increased performance improvements. IPA analyzes and optimizes your application as a whole, rather than on a file-by-file basis. PDF generates information that instructs the optimizer to focus on trade-offs that favor code that executes more frequently.

Get more performance from the POWER platform with minimal or no source code changes. Upgrade to the latest XL C/C++ or XL Fortran compiler, which incorporates the latest advances in optimization and hardware technology support.

OpenMP for offloading computation and data to the GPU

When combined with the POWER9 architecture, the NVIDIA GPU provides a unique platform for heterogeneous, high-performance computing, which has proven to be highly efficient for running several technical computing workloads. This computational capability is built on top of massively parallel and multi-threaded cores within the NVIDIA GPUs and the IBM POWER9 architecture. Parallel operations within applications, such as data analysis or HPC (high-performance computing) workloads, can now be offloaded to GPUs.

To fully leverage the computational power of the Power Systems with an NVIDIA GPU and to allow you to achieve performance uplift for your applications, you need to offload highly parallel operations to the GPU accelerator. OpenMP provides for a high level and homogeneous programming model to enable parallel computing to the GPU all within a single application compiled by the XL C/C++ or XL Fortran compiler. The OpenMP programming model, which is supported by the XL compilers, makes the underlying CPU and GPU hardware transparent to the programmer.

The OpenMP accelerator subcommittee has added features to the OpenMP specification (4.0 and 4.5) specifically to exploit servers that support offloading to accelerators such as GPUs. The IBM XL compiler team has representatives on the OpenMP committee. The XL compiler team works closely with the IBM Research team to develop the compiler infrastructure for the offloading mechanism. In addition, the team also collaborates with the open source community for the interface on the GPU device runtime library.

The XL compiler takes a holistic approach to optimize the POWER processor that is connected to the NIVIDA GPUs. In typical applications some parts of the code are suitable for running on a GPU for acceleration while other parts continue to be suitable to run on the CPU. The architecture of the XL compiler implementation for OpenMP allows for the CPU code to be optimized by the existing XL compiler POWER optimizer while the GPU code is optimized by the NVIDIA Toolkit optimizer. Finally the linker is invoked to link the objects to create a single executable. The NVIDIA NVLink interconnect continues to support accelerated data transfer between the CPU and GPU.

The goal is to deliver higher performance and greater energy efficiency to companies and data centers.

The OpenMP API supports multiplatform, shared-memory, parallel programming in C, C++, and Fortran on many architectures that use UNIX® and Microsoft™ Windows™ platforms. OpenMP is a portable, scalable programming model that gives programmers a simple and flexible, standard interface for developing parallel applications for platforms ranging from the desktop to the supercomputer.

This specification is defined by the OpenMP ARB, a group of leading hardware and software vendors and research organizations, including IBM. You can find more information about the OpenMP specifications at openmp.org website.

CUDA support for XL Fortran (on little endian distributions)

With CUDA Fortran support within XL Fortran for Linux, you can create applications that exploit both the POWER9 architecture and the NVIDIA GPU, and compile the complete application with the IBM XL compiler. You can continue to obtain the benefits of the IBM optimization technology within the XL Fortran compiler while fully leveraging the highly parallel capability of the NVIDIA GPU.

Clang infrastructure from LLVM

XL C/C++ for Linux (on little endian distributions) is built on the Clang (C language) technology from the open source community. Clang is a component of the LLVM open source compiler and toolchain project and provides the C and C++ language family front end for LLVM (formerly low level virtual machine). XL C/C++ for Linux (on little endian distributions) combines the Clang front-end technology with the advanced optimization technology from the IBM compiler back-end. The Clang front end within XL C/C++ for Linux (on little endian distributions) provides for a compiler that has a much greater level of GNU source compatibility. With the higher level of GNU source compatibility, porting of applications, which were originally developed with gcc and g++ compilers, is easier than ever before. Also, there is binary compatibility with GNU-built objects, archives, and other shared objects. You now have the versatility to use the IBM compilers to build parts of your application that will benefit from the higher performance that can be offered and still bind the IBM and GNU compiled parts together in a single application.

XL C/C++ for Linux and XL Fortran for Linux (on little endian distributions) Community Editions

The release of XL C/C++ for Linux Community Edition (on little endian distributions) and XL Fortran for Linux Community Edition (on little endian distributions) provides no-charge, full function compilers to developers and partners. The community editions are available for download from IBM. The release of the community editions allow for convenient availability of the XL C/C++ and XL Fortran compilers so that developers can experience the advantages of IBM compiler technology on the POWER9 platform. Users, who require a fully warranted, and fully supported compiler, can license the XL C/C++ for Linux and XL Fortran for Linux compilers.

An infrastructure that matters

The XL family of compilers, in conjunction with Power Systems, continues to serve the high-performance computing (HPC) and commercial sectors. This makes the high-performance XL C/C++ for Linux or XL Fortran for Linux compilers (on little endian distributions) an optimal fit for the requirements of big data and data analytics. One of the most discussed topics in the IT world is the migration of applications to a cloud environment. With an infrastructure that includes POWER9, the latest Linux distributions and the XL C/C++ for Linux or XL Fortran for Linux compilers, the effort to implement a cloud environment is easier. Organizations that need to invest in open standards and open source-based architectures, should consider the new XL C/C++ or XL Fortran compilers. Make XL C/C++ for Linux and XL Fortran for Linux the backbone of your IT application development environment to drive competitive differentiation.

IBM Service and Support

The XL C/C++ for Linux and XL Fortran for Linux compilers are delivered with IBM Service and Support. The IBM Service and Support organization is made up of teams of individuals who work together to provide you with the responsive platform and cross-platform software support that you require. For complex or code-related problems, IBM has specialized, skilled service teams with access to the experts in IBM development laboratories, as required. You have access to the right level of IBM expertise when you need it and no matter where they are located. The vision of IBM Service and Support is to achieve a level of support excellence that exceeds client expectations and differentiates IBM in the marketplace.

XL stands for exceptional

Originally coined in 1990, in the first edition of the Compiler User Guide, XL was described as a short form for exceptional. The following original text continues to apply today.

The exceptional (XL) family of compilers provide consistency and high performance across multiple programming languages by sharing the same code optimization technology.

Authorized User is a unit of measure by which the program can be licensed. An Authorized User is a unique person who is given access to the program. The program may be installed on any number of computers or servers and each Authorized User may have simultaneous access to any number of instances of the program at one time. Licensee must obtain separate, dedicated entitlements for each Authorized User given access to the program in any manner directly or indirectly (for example, through a multiplexing program, device, or application server) through any means. An entitlement for an Authorized User is unique to that Authorized User and may not be shared, nor may it be reassigned other than for the permanent transfer of the Authorized User entitlement to another person.

Note: Some programs may be licensed where devices are considered users. In that case, the following applies. Any computing device that requests the execution of or receives for execution a set of commands, procedures, or applications from the program or that is otherwise managed by the program is considered a separate user of the program and requires an entitlement as if that device were a person.


Concurrent User

Concurrent User is a unit of measure by which the program can be licensed. A Concurrent User is a person who is accessing the program at any particular point in time. Regardless of whether the person is simultaneously accessing the program multiple times, the person counts only as a single Concurrent User. The program may be installed on any number of computers or servers, but licensee must obtain entitlements for the maximum number of Concurrent Users simultaneously accessing the program. Licensee must obtain an entitlement for each simultaneous Concurrent User accessing the program in any manner directly or indirectly (for example, through a multiplexing program, device, or application server) through any means.

Note: Some programs may be licensed where devices are considered users. In that case, the following applies. Any computing device that requests the execution of or receives for execution a set of commands, procedures, or applications from the program or that is otherwise managed by the program is considered a separate user of the program and requires an entitlement as if that device were a person.

Terms and conditions

Top rule

The information provided in this announcement letter is for reference and convenience purposes only. The terms and conditions that govern any transaction with IBM are contained in the applicable contract documents such as the IBM International Program License Agreement, IBM International Passport Advantage Agreement, and the IBM Agreement for Acquisition of Software Maintenance.

Licensing

IBM International Program License Agreement including the License Information document and Proof of Entitlement (PoE) govern your use of the program. PoEs are required for all authorized use. Part number products only, offered outside of Passport Advantage, where applicable, are license only and do not include Software Maintenance.

This software license includes Software Subscription and Support (also referred to as Software Maintenance).

Agreement for Acquisition of Software Maintenance

The IBM Agreement for Acquisition of Software Maintenance (Z125-6011) applies for Subscription and Support (also referred to as Software Maintenance) and does not require customer signatures.

These programs are licensed under the IBM Program License Agreement (IPLA) and the associated Agreement for Acquisition of Software Maintenance, which provide for support with ongoing access to releases and versions of the program. IBM includes one year of Software Subscription and Support (also referred to as Software Maintenance) with the initial license acquisition of each program acquired. The initial period of Software Subscription and Support (also referred to as Software Maintenance) can be extended by the purchase of a renewal option, if available. These programs have a one-time license charge for use of the program and an annual renewable charge for the enhanced support that includes telephone assistance (voice support for defects during normal business hours), as well as access to updates, releases, and versions of the program as long as support is in effect.

The Agreement for Acquisition of Software Maintenance does not apply to XL C/C++ for Linux Community Edition nor XL Fortran for Linux Community Edition.

See the License Information documents page on the IBM Software License Agreement website for more information.

Limited warranty applies

Yes

Limited warranty

IBM warrants that when the program is used in the specified operating environment, it will conform to its specifications. The warranty applies only to the unmodified portion of the program. IBM does not warrant uninterrupted or error-free operation of the program or that IBM will correct all program defects. You are responsible for the results obtained from the use of the program.

IBM provides you with access to IBM databases containing information on known program defects, defect corrections, restrictions, and bypasses at no additional charge. For further information, see the IBM Software Support Handbook.

IBM will maintain this information for at least one year after the original licensee acquires the program (warranty period).

Program technical support

Technical support of a program product version or release will be available for a minimum of five years from the general availability date, as long as your Software Subscription and Support (also referred to as Software Maintenance) is in effect.

This technical support allows you to obtain assistance (by telephone or electronic means) from IBM for product-specific, task-oriented questions regarding the installation and operation of the program product. Software Subscription and Support (Software Maintenance) also provides you with access to updates (modifications or fixes), releases, and versions of the program. You will be notified, through an announcement letter, of discontinuance of support with 12 months' notice. If you require additional technical support from IBM, including an extension of support beyond the discontinuance date, contact your IBM representative or IBM Business Partner. This extension may be available for a fee.

For additional information on the IBM Software Support Lifecycle Policy, see the IBM Software Support Lifecycle Policy website.

Money-back guarantee

If for any reason you are dissatisfied with the program and you are the original licensee, you may obtain a refund of the amount you paid for it, if within 30 days of your invoice date you return the program and its PoE to the party from whom you obtained it. If you downloaded the program, you may contact the party from whom you acquired it for instructions on how to obtain the refund.

For clarification, note that (1) for programs acquired under the IBM International Passport Advantage offering, this term applies only to your first acquisition of the program and (2) for programs acquired under any of IBM's On/Off Capacity on Demand (On/Off CoD) software offerings, this term does not apply since these offerings apply to programs already acquired and in use by you.

Volume orders (IVO)

Yes. Contact your IBM representative.

Passport Advantage applies

Yes, information is available on the Passport Advantage and Passport Advantage Express website.

Software Subscription and Support applies

Yes. Software Subscription and Support, also referred to as Software Maintenance, is now included in the Passport Advantage Agreement. Installation and technical support for the products announced in this announcement is provided by the Software Subscription and Support offering of the IBM International Passport Advantage Agreement. This fee service enhances customer productivity by providing voice or electronic access into the IBM support organizations.

IBM includes one year of Software Subscription and Support with the initial license acquisition of each program acquired. The initial period of Software Subscription and Support can be extended by the purchase of a renewal option.

While your Software Subscription and Support is in effect, IBM provides you assistance for your routine, short duration installation and usage (how-to) questions, and code-related questions. IBM provides assistance by telephone and, if available, electronic access, only to your information systems (IS) technical support personnel during the normal business hours (published prime shift hours) of your IBM support center. (This assistance is not available to your users.) IBM provides Severity 1 assistance 24 hours a day, every day of the year. For additional details, see the IBM Software Support Handbook. Software Subscription and Support does not include assistance for the design and development of applications, your use of programs in other than their specified operating environment, or failures caused by products for which IBM is not responsible under this agreement.

For additional information about the Passport Advantage Agreement, go to the Passport Advantage and Passport Advantage Express website.

All distributed software licenses include Software Subscription and Support for a period of 12 months from the date of acquisition, providing a streamlined way to acquire IBM software and assure technical support coverage for all licenses. Extending coverage for a total of three years from date of acquisition, may be elected.

Variable charges apply

No

Educational allowance available

Yes. A 15% education allowance applies to qualified education institution customers.

Multi-Version Measurement

Multi-Version Measurement (MVM) replaces the previously announced Migration Grace Period time limit of six months and allows unlimited time for clients to run more than one eligible version of a software program. Clients may run multiple versions of a program simultaneously for an unlimited duration during a program version upgrade. Clients may also choose to run multiple versions of a program simultaneously for an unlimited duration in a production environment. MVM does not extend support dates for programs withdrawn from service.

For more information about MVM, including requirements for qualification, see the MVM web page. For a list of eligible programs, see the IPLA Execution-Based web page.

Statement of good security practices

Top rule

IT system security involves protecting systems and information through intrusion prevention, detection, and response to improper access from within and outside your enterprise. Improper access can result in information being altered, destroyed, or misappropriated or can result in misuse of your systems to attack others. Without a comprehensive approach to security, no IT system or product should be considered completely secure and no single product or security measure can be completely effective in preventing improper access. IBM systems and products are designed to be part of a regulatory compliant, comprehensive security approach, which will necessarily involve additional operational procedures, and may require other systems, products, or services to be most effective.

Important: IBM does not warrant that any systems, products, or services are immune from, or will make your enterprise immune from, the malicious or illegal conduct of any party.
