New release of MPICHArgonne 24 August 2001 The MPICH group at Argonne MPICH is an open-source, portable implementation of the Message-Passing Interface Standard. It contains a complete implementation of version 1.2 of the MPI Standard and also significant parts of MPI-2, particularly in the area of parallel I/O.released version 1.2.2 of MPICH, the portable MPI implementation.
Version 1.2.2 is primarily a bug-fix and improved-portability release,
particularly in the area of Linux support.
There are a number of improvements to the ch_p4 device that improve both
performance and reliability, particularly on Linux platforms.
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.
Argonne continues to enhance MPICH with a goal of full MPI-2 capability. In
addition, the group explores ways to improve the performance of MPICH. In
the queue are improved datatype handling and a new sockets implementation. In
the longer term, a new ADI with better support for multithreaded applications
and new network approaches will be introduced. One area where Argonne would like
contributions is better implementations of the collective routines. Please
contact Bob Gropp if you wouldlike to contribute (send mail to gropp@mcs.anl.gov).
