Robert,
Did you mean to install openmpi-1.2.6 in /usr. That is where the
apple supplied openmpi-1.2.3 in is installed. That doesn't appear to
be the problem causing your make install error. Were there any
warnings or errors when you ran make.

Hi all,
We're using a pingpong in order to measure the bandwidth and latency
available with open MPI.
In our first experiments done with the 1.1.4 version, we were using the
btl_tcp_eager_limit parameter to modify the eager limit. We've upgraded
to the 1.2.6 version and the limit parameter we
Actually, there is an unofficial processor affinity API on Mac OS X,
but it is supplied only with the CHUD framework. I suppose as a
further barrier to using this API in code outside of Apple, the header
files for this API are only available with the standalone CHUD
installer. See:

Just curious -- in regards to utilBindThreadToCPU(x), why does the

I don't think I have ever seen this one before. :(
So you are trying to checkpoint the MPI process by hand or a non-MPI
process? Can you confirm that you can successfully checkpoint/restart
a non-MPI process on these machines? What version of the Open MPI
trunk are you using? Have you made
Jeff,
The utilBindThreadToCPU(x) function is part of a private framework,
CHUD.framework, that is installed in
/System/Library/PrivateFrameworks. Apple provides but does not
support this framework. Any part of it could be changed or removed in
future releases of CHUD without any notice or deprec
