MPI (Message-Passing Interface) is a standard specification for
message-passing libraries. Mpich is a portable implementation of
the full MPI specification for a wide variety of parallel computing
environments, including workstation clusters and massively parallel
processors (MPPs). Mpich contains, along with the MPI library itself,
programming environment for working with MPI programs. The programming
environment includes a portable startup mechanism, several profiling
libraries for studying the performance of MPI programs, and an X interface
to all of the tools. This guide explains how to compile, test, and
install mpich and its related tools.
This document describes how to obtain and install mpich , the portable implementation of the MPI Message-Passing Standard. Details on using the mpich implementation are presented in a separate User's Guide for mpich . Version 1.2.2 of mpich is primarily a bug fix and increased portability release, particularly for Linux-based clusters.
New and improved in 1.2.2:
- A greatly improved ch_p4mpd device.
- Improved support for assorted Fortran 77 and Fortran 90 compilers, including compile-time evaluation of Fortran constants used in the mpich implementation.
- An improved globus2 device, providing better performance.
- A new bproc mode for the ch_p4 device supports Scyld Beowulfs.
- Many TCP performance improvements for the ch_p4 and ch_p4mpd devices, as well as
- Many bug fixes and code improvements. See www.mcs.anl.gov/mpi/mpich1/r1_2_2changes.html for a complete list of changes.
- Improved support for assorted Fortran and Fortran 90 compilers. In particular, a single version of mpich can now be built to use several different Fortran compilers; see the installation manual (in doc/install.ps.gz) for details.
- Using a C compiler for MPI programs that use mpich that is different from the one that mpich was built with is also easier now; see the installation manual.
- Known problems and bugs with this release are documented in the file mpich/KnownBugs .
- There is an FAQ at http://www.mcs.anl.gov/mpi/mpich1/faq.html . See this if you get ``permission denied'', ``connection reset by peer'', or ``poll: protocol failure in circuit setup'' when trying to run mpich.
