Hi, I've been working with mvapich2 from the OFED-1.2.5 release (I used http://www.openfabrics.org/downloads/OFED/ofed-1.2.5/OFED-1.2.5.tgz).
I've found a couple bugs in that version of mvapich2, which seem to also be present in the upstream SVN at https://mvapich.cse.ohio-state.edu/svn/mpi/mvapich2/branches/0.9.8 as of revision 1480. The first is an install tool bug: DESTDIR gets prepended twice in some cases, once when calling FixInstallFile and once inside it. The second is a memory-scribbling bug: in the call-chain rdma_cm_get_hostnames()->PMI_KVS_Get()->PMIU_getval() PMIU_getval() overwrites byte PMI_vallen_max - 1 (in my test case, PMI_vallen_max had value 2048) for a character array that has length 16. I'm not sure these are the right fixes, but with these patches applied, mvapich2 from ofed-1.2.5 installs correctly and runs tests it wouldn't run without them. -- Jim -- Jim Schutt <[EMAIL PROTECTED]> Sandia National Laboratories, Albuquerque, New Mexico USA diff -urN mvapich2-0.9.8.orig/src/mpe2/sbin/mpeinstall.in mvapich2-0.9.8/src/mpe2/sbin/mpeinstall.in --- mvapich2-0.9.8.orig/src/mpe2/sbin/mpeinstall.in 2006-04-09 11:57:00.000000000 -0600 +++ mvapich2-0.9.8/src/mpe2/sbin/mpeinstall.in 2007-08-31 10:02:10.000000000 -0600 @@ -442,10 +442,10 @@ echo "Copying MPE utility programs to $DESTDIR$bindir" CopyDirRecurP $binbuild_dir $bindir $XMODE if [ -s $binbuild_dir/mpecc -a -x $binbuild_dir/mpecc ] ; then - FixInstallFile $binbuild_dir/mpecc $DESTDIR$bindir/mpecc $XMODE + FixInstallFile $binbuild_dir/mpecc $bindir/mpecc $XMODE fi if [ -s $binbuild_dir/mpefc -a -x $binbuild_dir/mpefc ] ; then - FixInstallFile $binbuild_dir/mpefc $DESTDIR$bindir/mpefc $XMODE + FixInstallFile $binbuild_dir/mpefc $bindir/mpefc $XMODE fi fi fi @@ -457,7 +457,7 @@ CopyDirRecurP $etcbuild_dir $sysconfdir $MODE cd $etcbuild_dir && \ for file in *.conf ; do \ - FixInstallFile $file $DESTDIR$sysconfdir/$file ; \ + FixInstallFile $file $sysconfdir/$file ; \ done fi fi diff -urN mvapich2-0.9.8.orig/src/pmi/simple/simple_pmi.c mvapich2-0.9.8/src/pmi/simple/simple_pmi.c --- mvapich2-0.9.8.orig/src/pmi/simple/simple_pmi.c 2006-04-09 11:57:00.000000000 -0600 +++ mvapich2-0.9.8/src/pmi/simple/simple_pmi.c 2007-08-31 10:02:26.000000000 -0600 @@ -566,7 +566,7 @@ PMIU_getval( "rc", buf, PMIU_MAXLINE ); rc = atoi( buf ); if ( rc == 0 ) { - PMIU_getval( "value", value, PMI_vallen_max ); + PMIU_getval( "value", value, length ); return( 0 ); } else { _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
