entries in the hostfile are 'localhost'. However if I
add a host that isn't local I get a segmentation fault from the orted
process.
In any case, I distilled my example down as small as I could. I've
attached the C code of the master and the hostfile I'm using. He
al use I'm launching
something that calls MPI_Init.

Setting these environment variables did indeed change the way mpirun maps
things, and I didn't have to specify a hostfile. However, setting these
for my MPI_Comm_spawn code still resulted in the same segmentation fault.

I am unable to use PVFS2 with OpenMPI in a simple test program. My
configuration is given below. I'm running on RHEL5 with GigE (probably not
important).
OpenMPI 1.4 (had same issue with 1.3.3) is configured with
./configure --prefix=/work/rd/evan/archives/openmpi/openmpi/1.4/enable
Build pvfs2 correctly (I get conflicting info on whether the
"--with-mpi=..." is needed but FWIW, this is how I built it and it installs
into /usr/local which is it's default location...
cd
setenv CFLAGS -fPIC
./configure --with-mpi=/work/rd/evan/archives/openmpi/openmpi/1.4/ena
a trivial problem
but I'm hoping someone can give me an openmpi equivalent usage example.
Thanks in advance,
Evan
