Thanks Ralph. It's 1.8.1. I'll try this.

What version? If it’s 1.10 or I think even 1.8, you should have the “--bind-to
hwthread" option

Harald,
could you be more specific ?
btw, do you check the www.open-mpi.org main site or a mirror ?
the man pages looks good to me, and the issue you described was fixed
one month ago.
Cheers,

Why not start with the FAQ?

Hi,
I couldn't find any option in OpenMPI to bind a process to a hardware
thread. I am assuming this is not yet supported through binding options.
Could specifying a rank file be used as a workaround for this?
Thank you,
Saliya

Dear Ralph,
I am using Open MPI 1.10. I will recompile with "—enable-debug" and do as you
suggested. I get back in touch with more information soon.

Hello, everyone
I am struggling a bit with IB performance when sending data from a POSIX
shared memory region (/dev/shm). The memory is shared among many MPI
processes within the same compute node. Essentially, I see a bit hectic
performance, but it seems that my code it is roughly twice slowe
Is this a debug build of OMPI? In other words, was it configured with
—enable-debug? If so, you can get some further output to see what is causing
the problem by adding the following to your cmd line:
—leave-session-attached —mca plm_base_verbose 5 —mca state_base_verbose 5
BTW: what version o
Hello,
I am trying to run OpenMPI on a cluster where I am only allow to use RSH to
spawn processes across compute nodes. I modified my mpirun command in this way:
mpirun -np 48 --hostfile ./hostfile --mca plm_rsh_agent "rsh"
/central_storage/osu_barrier
the file "hostfile" contain the machine
