Installation Guide to mpich,a Portable Implementation of
MPIVersion 1.2.1
William Gropp and Ewing Lusk
This Guide corresponds to Version 1.2.1 of mpich. It was
processed by LaTeX on Tue Sep 5 14:51:06 2000.
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 [12], 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 [9].
Version 1.2.1 of mpich is primarily a bug fix and increased portability
release, particularly for LINUX-based clusters.
New in 1.2.1:
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.
-
Significant upgrades have been made to the MPD system of daemons that
provide fast startup of MPICH jobs, management of stdio, and a crude
parallel debugger based on gdb. See the README file in the
mpich/mpid/mpd directory and the mpich User's Guide for
information on how to use the MPD system with mpich.
-
The NT version of MPICH has been further enhanced and is available
separately; see the MPICH download page
http://www.mcs.anl/gov/mpi/mpich/download.html.
-
The MPE library for logging and program visualization has been much
improved. See the file mpe/README for more details.
-
A new version of ROMIO, 1.0.3, is included. See romio/README for
details.
-
A new version of the C++ interface from the University of Notre Dame is
also included.
-
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.
-
There is a paper on jumpshot available at
ftp://ftp.mcs.anl.gov/pub/mpi/jumpshot.ps.gz . A paper on MPD is available
at ftp://ftp.mcs.anl.gov/pub/mpd.ps.gz.
Features that were new
in 1.2.0 are:
-
Full MPI 1.2 compliance, including cancel of sends
-
IMPI (Interoperable MPI [3]) style flow control.
-
A Windows NT version is now available as open source. The
installation process for this version is different; this manual covers
only the Unix version of mpich.
-
Support for SMP-clusters in mpirun.
-
A Fortran 90 MPI module (actually two, see Section Fortran 90 Modules
).
-
Support for MPI_INIT_THREAD (but only for
MPI_THREAD_SINGLE)
-
Support for VPATH-style installations, along with a installation
process and choice of directory names that is closer to the
GNU-recommended approach
-
A new, scalable log file format, SLOG, for use with the MPE
logging tools. SLOG files can be read by a new version of Jumpshot
which is included with this release.
-
Updated ROMIO
-
A new device for networked clusters, similar to the p4 device but based
on daemons and thus supporting a number of new convenience features,
including fast startup. See the User's Guide for details.
Features that were new in 1.1.1 are:
-
The ROMIO subsystem implements a large part of the MPI-2 standard for
parallel I/O. For details on what types of file systems runs on and current
limitations, see the Romio documentation in romio/doc. ROMIO was
implemented by Rajeev Thakur at Argonne.
-
The MPI-2 standard C++ bindings are available for the MPI-1 functions.
These were implemented by Andrew Lumsdaine and Jeff Squyres of Notre Dame.
-
A new device, Globus2 device which replaces the previous Globus,
is available. It has been implemented by Nick
Karonis of Northern Illinois University and Brian Toonen of Argonne
National Laboratory.
-
A new program visualization program, called Jumpshot, is available
as an alternative to the upshot and nupshot programs. The
principal implementor is Omer Zaki of Argonne and Angelo State University.
