Installation Guide to mpich,a Portable Implementation of
MPIVersion 1.2.2
William Gropp and Ewing Lusk
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,
a
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 [11], 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 [8].
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/mpich/r1_2_2changes.html for a complete
list of changes.
Features that were new in 1.2.1 included:
-
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/mpich/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.
