Defining these parameters in my environment also did not resolve the
problem. Whenever I restart my program, the temporary files are getting
stored in the default /tmp directory instead of the directory I had
defined.

Define them in your environment prior to executing any of those commands.

When you say manually, do you mean setting these parameters in the
command line while calling mpirun, ompi-restart, and ompi-checkpoint? Or
is there another way to set these parameters?
Thanks

You shouldn't have to, but there may be a bug in the system. Try manually
setting both envars and see if it fixes the problem.

I have these parameters set in ~/.openmpi/mca-params.conf file
$ cat ~/.openmpi/mca-params.conf
orte_tmpdir_base = /home/ananda/ORTE
opal_cr_tmp_dir = /home/ananda/OPAL

Should I be setting OMPI_MCA_opal_cr_tmp_dir?
FYI, I am using openmpi 1.3.4 with blcr 0.8.2
Thanks

ompi-restart just does a fork/exec of the mpirun, so it should get the param if
it is in your environ. How are you setting it? Have you tried adding
OMPI_MCA_opal_cr_tmp_dir= to your environment?

Thanks Ralph.
Another question. Even though I am setting opal_cr_tmp_dir to a
directory other than /tmp while calling ompi-restart command, this
setting is not getting passed to the mpirun command that gets generated
by ompi-restart. How do I overcome this constraint?
Thanks

It's a different MCA param: orte_tmpdir_base

Hi,
I am working on parallelizing my sequential program using OpenMPI.
Although I got performance speedup using many threads, there was
slowdown on a small number of threads like 4 threads.
I found that it is because getc worked much slower than sequential
version. Does OpenMPI override or wrap ge
Absolutely. I'll get a package of stuff put together.

Just to be sure:
Is there a copy of the shared library on the other host (hpcnode1) ?

Hi all,
Me again (poor Shiqing, I know...). I've been trying to get the MUMPS
solver running on Windows with Open-MPI. I can only use the 1.5 branch
because that has Fortran support on Windows and 1.4.2 doesn't. There's
a couple of things going wrong:
First, calls to MPI_Initialized from
19 matches
