Re: [OMPI users] Restore MPI Communicator
There is no way to do such things, not in the MPI standard and not in any MPI implementation (except FT-MPI). There are discussions in the MPI Forum about adding such capabilities to the MPI standard. Anyway, you will have to wait for a while before having access to such features, the next MPI standard is not expected before 2010, and implementations of the standard will need at least one year to adapt. george.

Re: [OMPI users] Open MPI programs with autoconf/automake?
Hi,
see if this macro solves your problem:
http://autoconf-archive.cryp.to/acx_mpi.html
it requires some improvement, but might be a start. Since I only have
OpenMPI
I use it in the following way(it's not pretty):
configure.ac:
(...)
dnl Check for MPI
dnl This check will set the MPICC and MPICXX variables to the MPI compiler
ones
dnl if the library is found, or to the regular compilers if not.
AC_ARG_WITH(mpi, [AC_HELP_STRING([--with-mpi],
[enable MPI support [default=yes]])],
[case "${withval}" in
yes|no) with_mpi=$withval;;
*)
AC_MSG_ERROR(bad value ${withval} for --with-mpi);;
esac],
[with_mpi=yes])
if test "x$with_mpi" = "xyes"; then
ACX_MPI([], [AC_MSG_ERROR(could not find mpi library for --with-mpi)])
AC_DEFINE(HAVE_MPI)
MPI_CXXLIBS=`mpicxx --showme:link`
MPI_CXXFLAGS=`mpicxx --showme:compile`
AC_SUBST(MPI_CXXLIBS)
AC_SUBST(MPI_CXXFLAGS)
else
MPICC="$CC"
MPICXX="$CXX"
AC_SUBST(MPICC)
AC_SUBST(MPICXX)
fi
AM_CONDITIONAL([WE_HAVE_MPI],[test "x$with_mpi" = "xyes"])
(...)
Makefile.am:
(...)
# MPI headers/libraries:
INCLUDES+=$(MPI_CXXFLAGS)
OTHERLIBS+=$(MPI_CXXLIBS)
etc
I would start by improving the mentioned macro with specific support for each
MPI implementation...

[OMPI users] Restore MPI Communicator
Hi, If a process MPI stops irregularly (the process dies), can I restore the communicator processor survivors? Thanks.
Re: [OMPI users] stdout issues on nightly build
This is not a known issue. Can you provide more details?

Re: [OMPI users] Compiling on different servers
On Nov 6, 2008, at 10:33 PM, Robert Kubrick wrote: Moving one step foreword, server 1, my compile server, has a number of commercial C++ compilers (Pathscale and Intel). I'd like to compile different version of the binary with each compiler and then run these binaries on the Server 2 g++-compiled OMPI environments. The FAQ says "not really, you can't do that": http://www.open-mpi.org/faq/?category=sysadmin#multiple-installs , but I thought it might be time for an update with some hands-on experience? You probably still can't do this. C++ compilers have different symbol mangling schemes and generally do not create executables that are link compatible with g++. *Some* C++ compilers may be link compatible with g++ (I seem to recall someone mentioning this before); check your vendors' docs and/or try a simple non-MPI C++ app to see if it works. Good luck. -- Jeff Squyres Cisco Systems
