Overview
Bottom rule

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

Version 5.2 offers:

  • The ability to use the resource manager of your choice for submitting and managing batch or interactive parallel jobs. Or instead of using a separate resource manager, Parallel Environment manages the adapter resources itself, on behalf of the user application.
  • An enhanced LAPI designed to increase parallel application performance.
  • New environment variables for controlling the number of active I/O agents assigned to a job, which can help improve performance.
  • In addition to MPI and LAPI, Parallel Environment 5.2 provides support for other parallel programming APIs.
  • The use of the IBM MetaCluster Distributed Checkpoint Restart (MDCR) function to coordinate the checkpointing and restarting of jobs.
  • An OpenSSH based user authentication method.
  • Executable and library functions as 64-bit objects. The MPI library provides both 32-bit and 64-bit object support.
  • The IBM High Performance Computing Toolkit, which includes an Eclipse plug-in that integrates the IBM HPC Toolkit tools with the Eclipse Integrated Development Environment (IDE).

Note: IBM is continuing support for IBM General Parallel File System™ (GPFS™) for Power, V3.1 until September 30, 2010.

Description
Bottom rule

Beginning with Parallel Environment for AIX, V5.2 :

  • You can use the resource manager of your choice for submitting and managing batch or interactive parallel jobs. Parallel Environment 5.2 includes a set of resource management interfaces and data areas, for configuring your resource manager to interact with the parallel operating environment.

    Additionally, support is provided for running a job without a resource manager. You can launch a User Space job, using the InfiniBand interconnect, without the use of a resource manager such as LoadLeveler®. Instead of using a separate resource manager, Parallel Environment manages the adapter resources itself, on behalf of the user application.

  • IBM's MPI implementation exploits an enhanced LAPI designed to increase parallel application performance on clusters made up of Power Systems servers running the AIX operating system.
  • To help improve performance, new environment variables are provided for controlling the number of active I/O agents assigned to a job. Additionally, improvements have been made in the ability to run the parallel operating environment in large-scale environments.
  • In addition to MPI and LAPI, Parallel Environment 5.2 provides support for other parallel programming APIs. These APIs can be used in any combination in a single parallel program. Options are also included for specifying how the parallel APIs in your application will use system resources.
  • The underlying framework for the checkpoint and restart function has changed. Parallel Environment now uses the IBM MetaCluster Distributed Checkpoint Restart (MDCR) function, and its associated components, to coordinate the checkpointing and restarting of jobs. MDCR invokes the appropriate AIX Application Workload Partition (WPAR) commands on each node of a parallel job and coordinates the checkpoint and restart of those jobs.
  • Parallel Environment provides an OpenSSH based user authentication method. With this release, support for the cluster based security (CTSec) method will be removed. Compatibility (AIX based) security is still supported and continues to be the default security method.
  • Parallel Environment 5.2 provides its executable and library functions as 64-bit objects. The MPI library provides both 32-bit and 64-bit object support.
  • The IBM High Performance Computing Toolkit includes an Eclipse plug-in that integrates the IBM HPC Toolkit tools with the Eclipse Integrated Development Environment (IDE). The IBM HPC Toolkit tools can be used to instrument an application program in order to obtain application performance measurements for hardware performance counters, MPI tracing, OpenMP profiling, and I/O profiling. This plug-in also allows users to view this performance measurement data for their application.

Product positioning
Bottom rule

Parallel Environment for AIX can offer HPC users whose parallel applications use the industry-standard MPI a tool for creating and using parallel applications with a familiar look and feel. For those who need increased performance, Parallel Environment uses LAPI, which is provided on the Parallel Environment media.

Flexibility is provided through a new API allowing a choice of resource manager for submitting and managing batch or interactive parallel jobs. Or Parallel Environment can manage the adapter resources itself, on behalf of the user application.

Specified operating environment

Hardware requirements
  • IBM Power Systems (POWER6)
  • IBM BladeCenter Power Architecture servers (POWER6)

Parallel Environment is supported in a clustered environment interconnected with the InfiniBand host channel adapters and switches, running on IBM clusters.

In IP mode, Parallel Environment uses the standard UDP/IP protocol, which is available on many interconnects. Parallel Environment in IP mode is tested extensively on 1 Gb Ethernet and the InfiniBand host channel adapters.

Software requirements
  • AIX 6.1, TL 6100-04-01 or AIX 5.3, TL 5300-07-10
  • Parallel Environment APAR IZ59219 and IZ59288

If batch jobs are to be submitted under Parallel Environment, then an external scheduler is required. If using the preferred IBM TWS LoadLeveler, Version 4.1 (5765-L40) is required.

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 HPC Toolkit, the C and Fortran compiler and runtime requirements, along with other software requirements and instructions for downloading, are documented in the IBM High Performance Computing Toolkit Installation and Usage Guide provided on the CD-ROM.

If using the parallel checkpoint and restart function, the following is required:

  • APAR IZ59981
  • IBM General Parallel File System for AIX, V3.2.1, or later

Note: The supported node limit for parallel checkpoint restart is four nodes.

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

IBM Tivoli® Workload Scheduler LoadLeveler for AIX (5765-L40) can be used to submit batch parallel jobs. It can help assist with node allocation for job management.

General Parallel File System (GPFS) (5765-G66) is beneficial because 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 Power Systems servers and Power Architecture BladeCenter servers using the Parallel Environment MPI library for communications.

Compatibility

Parallel Environment 5.2 commands and applications are compatible only with AIX 5.3 and AIX 6.1, or later, and not with earlier versions of the AIX operating system.

If you are using TWS LoadLeveler as your resource manager, Parallel Environment 5.2 requires the 64-bit TWS LoadLeveler 4.1 shared library. Parallel Environment 5.2 does not work with earlier versions of TWS LoadLeveler.

All nodes in a parallel job must run the same versions of Parallel Environment, LAPI, and TWS LoadLeveler at the same maintenance levels. Parallel Environment 5.2 is only compatible with the following versions of LAPI and TWS LoadLeveler:

  • LAPI 3.1.4 (shipped with AIX 6.1) or 2.4.7 (shipped with AIX 5.3)
  • TWS LoadLeveler 4.1

Because Parallel Environment 5.2 is only compatible with TWS LoadLeveler 4.1, when Parallel Environment is migrated to Version 5.2, TWS LoadLeveler must also be migrated to V4.1.
Note: Existing Parallel Environment 5.1 customers should not attempt to use LAPI 3.1.4 or 2.4.7.

Limitations
  • Parallel Environment does not support interoperability between nodes running AIX and Linux® versions of Parallel Environment. Parallel jobs cannot be mixed between AIX and Linux Parallel Environment nodes.
  • 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 checkpoint and restart function will be available with APAR IZ59981 and is only available when running AIX 6.1 (TL 6100-04), or later. The supported node limit for checkpoint and restart is four nodes. For a list of other limitations, refer to the IBM Parallel Environment: MPI Programming Guide .
  • If checkpoint and restart is required with AIX 5.3, it is required to remain on Parallel Environment 5.1.

Planning information

Parallel Environment 5.2 is the last release that will support the AIX V5 operating system.

Packaging

IBM Parallel Environment for AIX is distributed as a single package available via CD-ROM media with the following:

  • IBM International Program License Agreement in multilanguage booklet (LC23-5052-01) and its License Information (L-RHAN-7T8M23) in multiple languages (ppe.loc.license)

To obtain pricing at less than full machine capacity for eligible products, you are required to:

  • Install and use, when available, IBM's license use management program, which installs with eligible IBM programs.
  • Install available updates to the operating system and eligible products such that license use can be accurately managed.
  • Determine if the use of sub-capacity pricing terms results in a reduced requirement for entitlements; you can reallocate the entitlement difference by distributing entitlements across a larger or different set of systems, or reserve them for future growth. There will be no refunds for these freed up entitlements. Subscription, Software Maintenance and support volumes, and entitlements for existing contracts will continue at the same levels as the acquired licenses.
