Hi,
I have a slightly odd problem, that you might not think is important
at all. Anyways, here it goes:
I'm using a single eight-core machine. I want to oversubscribe four of
the cores and leave the other four idle. My approach is to make a
hostfile:
localhost slot=4 # shouldn't this li

You are absolutely right; sorry about that. I have fixed the bug in
the OMPI development trunk which means that it will be incorporated in
the upcoming v1.3 series (see https://svn.open-mpi.org/trac/ompi/changeset/17395)
. I also filed a change request for the v1.2 branch; if we e
The whole question of how to invoke xterms for gdb via mpirun keeps
coming up, so when this thread is done, I'll add a pile of this
information to the FAQ.
More below.

Still, all eight cores are being used. I can see why you would want to
use all cores, and I can see that oversubscribing a sub-set of the
cores might seem silly. My question is, is it possible to do what I
want to do without hacking the open mpi code?
Could

Hi Stefan,
I was able to verify the problem. Turns out this is a problem with other
onesided operations as well. Attached is a simple test case I made in c
using MPI_Put that also fails.
The problem is that the target count and displacements are both sent as
signed 32 bit integers. Then, the
Hi Brock,
As far as I know there is no way to do this with Open MPI and torque. I
believe people usually use hostfiles to do this sort of thing, but
hostfiles do not work with torque.
You may want to look into the launcher commands to see if torque will do
it for you. Slurm has an option '--
Kenneth,
Have you tried the 1.2.5 version? There were some fixes to the
vector collectives that could have resolved your problem.

The fix I previously sent to the list has been committed in r17400.
Thanks,

What I missed in this whole conversation is that the pieces of text
that Ron and Dick are citing are *on the same page* in the MPI spec;
they're not disparate parts of the spec that accidentally overlap in
discussion scope.
Specifically, it says:
