Could you point to that post, or tell us what to try excatly, given
we're running IMB? Thanks

Answer to my own question.
It was simply a noob problem - not using mpiexec to run my
'application'. Once I did this, everything is running as expected. My
bad for not reading more before jumping in.

I've seen the same thing when I build openmpi 1.4.3 with Intel 12, but only
when I have -O2 or -O3 in CFLAGS. If I drop it down to -O1 then the collectives
hangs go away. I don't know what, if anything, the higher optimization buys you
when compiling openmpi, so I'm not sure if that's an accepta
That would be a problem, I fear. We need to push those envars into the
environment.
Is there some particular problem causing what you see? We have no other reports
of this issue, and orterun has had that code forever.

Hi , I am working on mpi
I've have installed openmpi 1.4.3 with blcr included.
I ran a simple mpi application using a hostfile:
pc1 slots=2 max-slots=2
pc2 slots=2 max-slots=2
And, i ran command to run it with checkpoint supported
#mpirun --hostfile myhost -np 4 --am ft-enable-cr ./mpi_app

Did you copy OMPI to the same directory tree that you built it?
OMPI hard-codes some directory names when it builds, an

the "load" will be zero until the broadcast actually fires. But I'm concerned
about the pending resource usage (i.e., how many internal network and

After setting OPAL_PKGDATADIR, "mpirun" gives proper help message.
But when executing simple test program which calls MPI_ALLREDUCE() it
gives following errors onto the console...
c:\ompi_tests\win64>mpirun mar_f_i_op.exe
[nbld-w08:04820] [[30632,0],0] ORTE_ERROR_LOG: Error in file
..\..\..\openm
It's my mistake it should be OPAL_PKGDATADIR env var instead of OPAL_DATADIR.
With this it is working fine.
Thank you.
