Hi All,
We have bundled Open MPI with our product and shipped it to the
customer. According to http://www.open-mpi.org/faq/?category=building#installdirs
,
Below is the command we used to launch MPI program:
env OPAL_PREFIX=/path/to/openmpi \
/path/to/openmpi/bin//orterun --prefix /path/to/openmpi -x PATH -x
LD_LIBRARY_PATH -x OPAL_PREFIX -np 2 --host host1,host2 ring_c
The interesting fact is that it always works on csh/tcsh. But quite a
few users told us that they runs into below errors:
[compute-28-1.local:11174] [NO-NAME] ORTE_ERROR_LOG: Not found in file
runtime/orte_init_stage1.c at line 182

Sorry! You were supposed to get help about:
orte_init:startup:internal-failure
from the file:
help-orte-runtime
But I couldn't find any file matching that name. Sorry!

Jeff did mention in http://www.open-mpi.org/community/lists/users/2008/09/6582.php
that OPAL_PREFIX was propagated for him automatically. I bet Jeff
uses csh/tcsh.
Anyway, it can be traced back to how the daemon is launched.
sh/bash:
[xxxxx:25369] pls:rsh: executing: (//usr/bin/ssh) /usr/bin/ssh xxxxx
OPAL_PREFIX=/opt/openmpi-1.2.4 ;
PATH=/opt/openmpi-1.2.4/bin:$PATH
; export PATH ;
LD_LIBRARY_PATH=/opt/openmpi-1.2.4/lib:$LD_LIBRARY_PATH ; export
LD_LIBRARY_PATH ;
csh/tcsh:
[xxxxx:09886] pls:rsh: executing: (//usr/bin/ssh) /usr/bin/ssh xxxxx
setenv OPAL_PREFIX /opt/openmpi-1.2.4 ;
It seems to work after I patched pls_rsh_module.c

Another workaround is to add
export OPAL_PREFIX
into $HOME/.bashrc.
Jeff, is this a bug in the code? Or there is a reason that
OPAL_PREFIX is not exported for sh/bash?
