MPT is a software package that supports interprocess data exchange for applications that use concurrent, cooperating processes on a single host or on multiple hosts. Data exchange is done through message passing, which is the use of library calls to request data delivery from one process to another or between groups of processes. The MPT 1.3 release is supported on the following platforms: • Cray PVP systems running UNICOS release 10.0 or later. The MPT 1.3 release requires a bugfix package to be installed on UNICOS systems running release 10.0.0.0 or 10.0.0.1. The bugfix package, MPT12_OS_FIXES, is available through the getfix utility. It is also available from the anonymous FTP site ftp.cray.com in directory /pub/mpt/fixes/MPT12_OS_FIXES. • CRAY T3E systems running UNICOS/mk release 1.5 or later. • Silicon Graphics MIPS based systems running IRIX release 6.2 or later. IRIX 6.2 systems running Parallel Virtual Machine (PVM) require the POSIX patch set and any patches recommended by the patch set. IRIX 6.2 systems running Message Passing Interface (MPI) require the kernel rollup patch 1650 or later. IRIX 6.3 systems running MPI require the kernel rollup patch 2328 or later. IRIX systems running MPI applications must also be running Array Services software version 3.0 or later. IRIX systems using the Miser feature must be running IRIX 6.5 or later and Array Services version 3.1 or later. MPI jobs that use the checkpoint and restart feature require IRIX 6.4 plus kernel patch 2839 and CPR patch 2689, or IRIX 6.5. In addition, CPR patch 3017 fixes IRIX 6.4 and IRIX 6.5 problems that exist with the ash (array session handler) option of the cpr(1) command. Array Services 3.1 or later is also required for this feature. Activation of the MPI usability improvements feature is dependent on Array Services 3.2 plus patch 3532. 007–3689–003 1 Message Passing Toolkit: Release Notes These release notes include information about the following: • New features • Compatibilities and differences • Documentation • Customer services • Release package contents The remainder of this chapter discusses the following topics: • MPT components • MPT software • Product description • Distribution of these release notes • Reader comments 1.1 MPT Components The MPT 1.3 package contains the following components and accompanying documentation: • Parallel Virtual Machine (PVM) • Message Passing Interface (MPI) • Logically shared, distributed memory (SHMEM) message passing routines The PVM and MPI components of MPT are based on industry standards for the message passing programming model. These components also contain enhancements specific to Silicon Graphics and Cray Research systems. For a description of MPI, see the Message Passing Toolkit: MPI Programmer’s Manual. For a description of PVM, see the Message Passing Toolkit: PVM Programmer’s Manual. The SHMEM library is packaged with MPT on UNICOS and IRIX systems only. On UNICOS/mk systems, the SHMEM library is delivered with the CrayLibs package. SHMEM man pages are printed in the Application Programmer’s Library Reference Manual. 2 007–3689–003 Introduction [1] 1.2 MPT Software For UNICOS and UNICOS/mk systems, software included in MPT was designed to be used with the Cray Programming Environment 3.0 release or later. The Modules software package is used to support the installation of both the Programming Environment and MPT. To use the MPT software, load the mpt module in addition to loading the Programming Environment module. For information on using modules, see Installing

  • CRAY T90 Series IEEE Floating Point Migration Issues and Solutions
    CRAY T90 Series IEEE Floating Point Migration Issues and Solutions Philip G. Garnatz, Cray Research, Inc., Eagan, Minnesota, U.S.A. ABSTRACT: Migration to the new CRAY T90 series with IEEE floating-point arith- metic presents a new challenge to applications programmers. More precision in the mantissa and less range in the exponent will likely raise some numerical differences issues. A step-by-step process will be presented to show how to isolate these numerical differences. Data files will need to be transferred and converted from a Cray format PVP system to and from a CRAY T90 series system with IEEE. New options to the assign command allow for transparent reading and writing of files from the other types of system. Introduction This paper is intended for the user services personnel and 114814 help desk staff who will be asked questions by programmers and exp mantissa users who will be moving code to the CRAY T90 series IEEE from another Cray PVP architecture. The issues and solutions Exponent sign presented here are intended to be a guide to the most frequent problems that programmers may encounter. Mantissa sign What is the numerical model? Figure2: Cray format floating-point frames and other computational entities such as workstations and New CRAY T90 series IEEE programmers might notice graphic displays. Other benefits are as follows: different answers when running on the IEEE machine than on a system with traditional Cray format floating-point arithmetic. • Greater precision. An IEEE floating-point number provides The IEEE format has the following characteristics: approximately 16 decimal digits of precision; this is about one and a half digits more precise than Cray format numbers.
