Parallel Environment for AIX is a high-function development and execution environment for parallel applications running on one or more IBM Power System servers.

Parallel Environment for AIX can offer High Performance Computing (HPC) users whose parallel applications use the industry-standard Message Passing Interface (MPI) a tool for creating and using parallel applications with a familiar look and feel. IBM's MPI implementation exploits an enhanced low-level application programming interface (LAPI) designed to increase parallel application performance on clusters made up of Power System servers running the AIX® operating system.

Version 5 offers:

  • Support for the POWER6 barrier synchronization register, which may enhance collective communication performance within the SMP.
  • The IBM High Performance Computing Toolkit (HPCT), which replaces PE Benchmarker.. The HPCT is an integrated software environment that addresses the performance analysis, tuning, and debugging of sequential and parallel scientific applications.
  • A PDB debugger, which replaces pdbx, includes mechanisms for filtering and controlling message output.
  • Support for Fortran 90 modules that provides type checking for MPI programs at compile time.
  • LAPI provides new multicast APIs that are designed to boost performance on adapters and switches that support multicast capability.

Specified operating environment

Hardware requirements
  • IBM Power Systems (POWER6)
  • IBM System p5® (POWER5)
  • IBM BladeCenter Power Architecture servers
  • Cluster 1600 when consisting of the supported servers

Parallel Environment is supported in a clustered environment interconnected with either the IBM High Performance Switch or the InfiniBand host channel adapters and switches, running on IBM clusters. Parallel Environment in IP mode uses the standard UDP/IP protocol, which is available on many interconnects. Parallel Environment in IP mode is tested extensively on 1 Gb Ethernet.

Software requirements
  • AIX 6.1, TL 6100-02 or AIX 5.3, TL 5300-09
  • Parallel Environment APAR IZ31432

If batch or interactive user space jobs are to be submitted under Parallel Environment, then IBM Tivoli® Workload Scheduler LoadLeveler® V3.5 (5765-E69) is required. Minimal support for a customer-supplied scheduler is provided via sample code.

If Fortran or C/C++ programs are to be developed, you will need a supported level of the specific compiler. Refer to the Parallel Environment Installation Guide for the required levels.

If using the HPCT to measure and analyze the performance of your application, APAR IZ31484 is required. Other required software is included in the HPCT installation package provided on the CD-ROM. Additionally, HPCT requires the following AIX filesets:

  • AIX 5.3: bos.pmapi, or later
  • AIX 6.1: bos.pmapi, or later

For support with the InfiniBand switch, the following service updates are required:

Running AIX 6.1: APAR IZ35509, IZ35510, and IZ35525
Running AIX 5.3: APAR IZ35509, IZ35511, and IZ35524

The program's specifications and specified operating environment information may be found in documentation accompanying the program, if available, such as a readme file, or other information published by IBM, such as an announcement letter. Documentation and other program content may be supplied only in the English language.

Companion products

The following products could be purchased with this product:

  • Tivoli Workload Scheduler LoadLeveler (5765-E69) can be used for submission of batch parallel jobs. It can help assist with node allocation for job management.
  • General Parallel File System™ (GPFS™) (5765-G66) is beneficial because Message Passing Interface - Input/Output (MPI-IO) depends on the underlying file system's ability to maintain file consistency when multiple tasks modify a file. An MPI job distributes tasks across many nodes and these tasks commonly do large amounts of concurrent and even coordinated file I/O.

    GPFS is designed to deliver high-performance parallel I/O between the file system and the tasks of the MPI job. MPI-IO, part of the Parallel Environment MPI, is designed to work correctly and efficiently with GPFS. Using MPI-IO for highest performance depends on the consistency for access from multiple nodes that only a true parallel file system like GPFS can provide.

  • Parallel Engineering and Scientific Subroutine Library (Parallel ESSL) (5765-F84) is a scalable mathematical subroutine library that provides outstanding performance through simple subroutine calls for engineering and scientific MPI applications on clusters of System p® servers and Power Architecture based BladeCenter servers using the Parallel Environment MPI library for communications.

The pdbx debugger function is removed from PE V5.1 and replaced with the PDB debugger, previously only available on PE for Linux®. This PDB debugger includes mechanisms for filtering and controlling message output.

  • In order to utilize the POWER6 barrier synchronization register (BSR), you must be running 64-bit programs over AIX 6.
  • You cannot use BSR if you are using the checkpoint and restart function of PE.

Version 5.1 ships the HPCT, which replaces PE Benchmarker. This includes the removal of the:

Performance Collection Tool
Performance Visualization Tool
Unified Trace Environment utilities

The supported node limit for Parallel Environment is 64 nodes. However, for clusters larger than 64 nodes, a request can be submitted through special bid. The current architectural limits for Parallel Environment V5.1 is 256,000 tasks.

Planning information

Version 5.1 is the last release that will support:

  • The IBM High Performance Switch
  • The IBM BladeCenter JS21 with a BladeCenter H chassis interconnected with the InfiniBand Host Channel Adapters connected to a Cisco InfiniBand SDR switch
  • The Power System 575 (Model 9118-575) and Power System 550 (Model 9133-55A) interconnected with the InfiniBand Host Channel Adapter and Cisco switch

A processor (commonly called a CPU or core) is the unit of measure by which this program is licensed. It is a functional unit within a computing device that interprets and executes instructions. A processor consists of at least an instruction control unit and one or more arithmetic or logic unit. With multicore technology, each core is considered a processor. A Proof of Entitlement (PoE) must be obtained for the appropriate number of processors based on the level of all processor cores activated and available for use by the program on the server.

Sub-capacity processor

Some programs allow licensing to less than the full capacity of the servers activated processor cores, sometimes referred to as sub-capacity licensing. For programs which offer sub-capacity licensing, if a server is partitioned utilizing eligible partitioning technologies, then a PoE must be obtained for the appropriate number of processors based on all activated processor cores available for use in each partition where the program runs or is managed by the program. Refer to the program's License Information to determine applicable sub-capacity terms. The entitlements are specific to the program and may not be exchanged, interchanged, or aggregated with entitlements of another program.
