Has anyone in the list ever tested openMPI in infiniband network
in which openSM is running with LASH routing algorithm enabled?
I haven't tested the above case but i could foresee a problem
because LASH routing algorithm in openSM uses virtual
lanes (VL) which are directly mapped with service lev
Hello Guys,
When is the version 1.3 scheduled to be released? As it would contain
checkpointing, library for non-blocking communication, ConnectX for QP's, it
would be great to have it ASAP. Since i am evaluating MVAPICH against OpenMPI,
i found that MVAPICH still has upper hand in terms of

This is to be expected. OMPI's support for THREAD_MULTIPLE is
incomplete and most likely doesn't work.

Well, that's odd.
What happens if you try to mpirun "hostname" (i.e., a non-MPI
application)? Does it run, or does it hang?

There is work starting literally right about now to allow Open MPI to
use the RDMA CM and/or the IBCM for creating OpenFabrics connections

Roland thought that the default value of 10 might be a bit too low and
that tuning it to be higher, particularly in apps that pound on a
single port, would probably be acceptable.
Tuning up to 20 is probably a bit overkill.

What value do you suggest then? I know I've seen the problem persist at
values of 14 and 16, and would rather be certain that this isn't going
to kill the job that just sat in the queue for a week.

thank you for your answer...

Ok,
v1.3's schedule is being developed right now -- it was a little hard
to hear on the teleconference yesterday, but I think I heard Brad
Benton from IBM (one of the two Release Managers for the v1.3 series)
say that he'd have a plan for review by the group next week.
So far, I've been [wildly
For what it's worth Andrew, the RETRY_EXCEEDED_ERRORS can be caused by
flaky hardware as well. The timeout value is probably best tuned
relative to the size of your IB fabric. But if reliability is the
biggest criteria, crank up the timemout value to 20. That's the best
you can do. If it contin
If your F77 compiler do not support array of LOGICAL variables (which
seems to be the case if you look in the config.log file), then you're
left with only one option. Remove the F77 support from the
compilation. This means adding the --disable-mpi-f77 option to the ./
configure.
Thanks,

I am new to openmpi and have a problem that I cannot seem to solve.
I am trying to run the hello_c example and I can't get it to work.
I compiled openmpi with:

Hi everybody out there.
This is my first post to the mail list.
I have installed openmp 1.2.4 over a x_64 AMD double processor with SuSE
linux.
In principal, the instalation was succefull, with ifort 10.X.
But when i run any code ( mpirun -np 2 a.out), instead of share the

That's what's supposed to happen, it's how MPI works. Process 0 is the
head or boss process, and the others are slaves, and execute partially
different code even though they're in the same executable. MPI is
multi-process, not multi-thread.

Henry,
Apologies ahead of time for any unintended insults, but...
Your "a.out" sounds like it is not truly a parallel code. If you
submit a hello_world program using OpenMPI's mpirun, you will simply
get two copies of "Hello World" printed to the screen.
