Hi everybody,

we've got some problems on our cluster with openmpi versions 1.2 and
upward.

The following setup does work:

openmpi-1.2b3: SLES 9 SP3 with gcc/g++ 4.1.1 and PGI f95 6.1-1

The following two setups give a SISEGV in mpiexec (stack see below)

openmpi-1.2: SLES 9 SP3 with gcc/g++ 4.1.1 and PGI f95 6.1-1
openmpi-1.2.1: SLES 9 SP3 with gcc/g++ 4.1.1 and PGI f95 6.1-1

All have been compiled with

export F77=pgf95
export FC=pgf95
 
./configure --prefix=/sw/sles9-x64/voltaire/openmpi-1.2b3-pgi \
            --enable-pretty-print-stacktrace \
            --with-libnuma=/usr \
            --with-mvapi=/usr \
            --with-mvapi-libdir=/usr/lib64

(with changing prefix, of course)

The stack trace:

In case access to our cluster could help, we would be happy to
provide an account.

Cheerio,
