[goodell@mcs.anl.gov: [mpich2-announce] Announcing the availability of MPICH2 1.5b1]



Hi,

I've made the initial work towards a working package for mpich2 1.5
(pushed to git).

I think that this version should be targeted for Debian wheezy instead
of the current 1.4.1. However, for this to happen, we need a working
package uploaded to unstable by the end of this month.

Dave, do you have a release schedule for 1.5? Do you know when the
final release is expected ? Is the 1.5 branch in feature-freeze, or is
development still happening?

Torquil, Adam, will you have time to work on this? I have limited time
currently, unfortunately. (also, I'd like to step down from mpich2
maintenance not too far in the future, due to my limited time)

Dave, It seems that the mpeinstall script assumes that the following
directories exist:
$DESTDIR/usr/bin ; $DESTDIR/usr/sbin ; $DESTDIR/etc/mpich2 ; $DESTDIR/usr/share/man/man4
Could you check if there's something wrong there?

  Lucas

A new release of MPICH2 (1.5b1) is available from http://www.mcs.anl.gov/research/projects/mpich2/downloads/index.php?s=downloads

This is a feature-preview release. MPICH2 developers, testers and other
advanced users are encouraged to try this release out and let us know if
you encounter any problems. This release is not intended for production
systems at this time; such systems should continue to use the latest
release from the 1.4.x branch (currently 1.4.1p1).

The major additions in the 1.5b1 release since 1.4.1p1 are highlighted below.

(Windows binaries are not available at this time)

Regards,
The MPICH2 Team

===============================================================================
                               Changes in 1.5
===============================================================================

 # OVERALL: nemesis now supports an "--enable-yield=..." configure option for
   better performance/behavior when oversubscribing processes to cores.  Some
   form of this option is enabled by default on Linux, Darwin, and systems that
   support sched_yield().

 # MPI-3: the new MPI-3 nonblocking collectives functions are now available as
   "MPIX_" functions (e.g. "MPIX_Ibcast").

 # MPI-3: the new MPI-3 MPI_Comm_split_type function is now available
   as an "MPIX_" function.

 # MPI-3: the new MPI-3 tools interface is now available as "MPIX_T_"
   functions.  This is a beta implementation right now with several limitations,
   including no support for multithreading.  Several performance variables
   related to CH3's message matching are exposed through this interface.

 # MPI-3: the new MPI-3 matched probe functionality is supported via the new
   routines MPIX_Mprobe, MPIX_Improbe, MPIX_Mrecv, and MPIX_Imrecv.

 # MPI-3: the new MPI-3 nonblocking communicator duplication routine,
   MPIX_Comm_idup, is now supported.  It will only work for single-threaded
   programs at this time.

 # MPI-3: MPIX_Comm_reenable_anysource support

 # MPI-3: native MPIX_Comm_create_group support (updated version of the prior
   MPIX_Group_comm_create routine).

 # MPI-3: eliminated the possibility of interference between
   MPI_Intercomm_create and point-to-point messaging operations.

 # Build system: Completely revamped build system to rely fully on
   autotools.  Parallel builds ("make -j8" and similar) are now supported.

 # Build system: rename "./maint/updatefiles" --> "./autogen.sh" and
   "configure.in" --> "configure.ac"

 # PM/PMI: Upgrade hwloc to 1.4.1.

 # JUMPSHOT: Improvements to Jumpshot to handle thousands of
   timelines, including performance improvements to slog2 in such
   cases.

 # JUMPSHOT: Added navigation support to locate chosen drawable's ends
   when viewport has been scrolled far from the drawable.

 # PM/PMI: Upgraded to hwloc-1.4.1

 # Several other minor bug fixes, memory leak fixes, and code cleanup.
