Tamer,
This should now be fixed in r18241.
Though I was able to replicate this bug, it only occurred
sporadically for me. It seemed to be caused by some socket descriptor
caching that was not properly cleaned up by the restart procedure.
My testing appears to conclude that this bug is now

The paper you cited, while presenting a particular implementation
doesn't bring present any new ideas. The compression of the data was
studied for long time, and [unfortunately] it always came back to the
same result. In the general case, not worth the effort !
Now of course, if one limit i
Hi list,
I had a similar problem last year with IMB when the the job would just
hang on a PowerPC cluster, for which Jeff Sqyres gave me many pointers
to change paramaters to fix the problem. Now with another cluster that I
am building the IMB job hangs in the same place and also the machines

Tamer,
Just wanted to update you on my progress. I am able to reproduce
something similar to this problem. I am currently working on a
solution to it. I'll let you know when it is available, probably in
the next day or two.
Thank you for the bug report.
Cheers,
Josh

Is this true and how it can be used?
Does anyone have any experiences about using it?

I am sure. I have separate VMware-instances installed in order to
avoid any interdependencies.
FWIW, you might not want to comment out this line, but rather move up
any OMPI setup to *before* this line (so that it is processed both
during interactive and non-interactive logins).
The check for a non/interactive login may well be there for a reason;
there may well be things past that

Make sure you're using the "right" mpirun. If you have both MPICH and
Open MPI installed, you need to install them into the different
directories.
As for not finding the "orted" on the remote nodes, it simply means
that your PATH / LD_LIBRARY_PATH is not set properly on the remote
nodes.
Glad that worked, my comment was that your gcc.error output looked
similar to the issues described in the faq not that the faq would solve
the issue using the gcc compiler. Sorry I wasn't clearer.
Note, I think most of these issues are resolved in 1.3 (the current
trunk) though I believe tick

A couple things to try
Put -np 2 after -hostfile /home/stephan/mpd.hosts
put the command you want to run after -np 2
