Sun MPI 4.0 User's Guide: With LSF

Sun HPC ClusterTools 3.0 Software and LSF Suite 3.2.3

Sun HPC ClusterTools 3.0 software is an integrated ensemble of parallel development tools that extend Sun's network computing solutions to high-end distributed-memory applications. The Sun HPC ClusterTools products are teamed with LSF Suite 3.2.3, Platform Computing Corporation's resource management software.

Sun HPC ClusterTools software runs under Solaris 2.6 or Solaris 7 (32- or 64-bit).

Load Sharing Facility

LSF Suite 3.2.3 is a collection of resource-management products that provide distributed batch scheduling, load balancing, job execution, and job termination services across a network of computers. The LSF products required by Sun HPC ClusterTools 3.0 software are: LSF Base, LSF Batch, and LSF Parallel.

Sun MPI and MPI I/O

Sun MPI is a highly optimized version of the Message-Passing Interface (MPI) communications library. Sun MPI implements all of the MPI 1.2 standard as well as a significant subset of the MPI 2.0 feature list. For example, Sun MPI provides the following features:

Sun MPI and MPI I/O provide full F77, C, and C++ support and Basic F90 support.

Parallel File System

The Sun Parallel File System (PFS) component of the Sun HPC ClusterTools suite of software provides high-performance file I/O for multiprocess applications running in a cluster-based, distributed-memory environment.

PFS file systems closely resemble UFS file systems, but provide significantly higher file I/O performance by striping files across multiple PFS I/O server nodes. This means the time required to read or write a PFS file can be reduced by an amount roughly proportional to the number of file server nodes in the PFS file system.

PFS is optimized for the large files and complex data access patterns that are characteristic of parallel scientific applications.

Prism

Prism is the Sun HPC graphical programming environment. It allows you to develop, execute, debug, and visualize data in message-passing programs. With Prism you can

Prism can be used with applications written in F77, F90, C, and C++.

Sun S3L

The Sun Scalable Scientific Subroutine Library (Sun S3L) provides a set of parallel and scalable functions and tools that are used widely in scientific and engineering computing. It is built on top of MPI and provides the following functionality for Sun MPI programmers:

Sun S3L routines can be called from applications written in F77, F90, C, and C++.

Sun Compilers

Sun HPC ClusterTools 3.0 software supports the following Sun compilers:
