Which source checkout did you use? Note that the pls structures have
likely changed between the OMPI SVN trunk and the v1.2 branch.
Hmm -- are you saying that you tried compiling the Apple copy of the
rsh pls and/or the OMPI SVN v1.2.3 rsh pls and neither of them worked?
Yes, I tried both of those and they gave the same bus error. If I'm
reading the stack dump right:
[Rotarran-X-5:04475] Failing at address: 0x0
[ 1] [0xbffff828, 0x00000000] (-P-)
[ 2] (orterun + 0x457) [0xbffff8b8, 0x00001d07]
it's orterun() calling a null pointer.
I don't rightly know why that wouldn't work -- is there a way to know
with what compiler flags Apple built Open MPI?
I'm not sure, but I think these are the configure flags they use:
--disable-mpi-f77 --without-cs-fs -enable-mca-no-build=ras-slurm,pls-
slurm,gpr-null,sds-pipe,sds-slurm,pml-cm --mandir=/usr/share/man --
sysconfdir=/usr/share NM="nm -p"
Can you step through
mpirun with a debugger to see where it dies? I suspect it may not
have any debugging symbols, so you might not, but at least you might
be able to see which pls rsh functions are invoked...? (and more
importantly, if something is invoked "wrong" in the pls rsh)
Adding some printf's into the pls rsh shows the _init and _open
routines are successfully executing and exiting. I'll see if I can
figure out what part of orterun() is "orterun + 0x457". I have not
attempted to replace orterun/mpirun/etc., only the pls pieces.
Thank you,
Dean
