Hello,
I'm looking over some MPI code and saw something that concerned me.
Being a bit new to MPI I don't know if this is a bug or "normal'.
A call to MPI_Isend was made and followed by an MPI_Reqest_free on the
exact same request handle used in the Isend call. I saw the same thing
for ISsend.
Hello,
I would really appreciate any advice on troubleshooting/tuning Open MPI over
ConnectX. More details about our setup can be found here

process per node (ppn=1) seems to be fine (the results for IMB can be found

Hello Tim and list
Having been listening and participating on this interesting thread from
the very beginning,
I would like to add another two cents.
I don't oppose moving the specific discussion of OpenMPI memcpy
implementation to the developers' list.
I am not a developer (or qualified to
A number of distributors provide pre-compiled Open-MPI packages, so one
doesn't need to go to the trouble of compiling it. For example, on
Debian GNU/Linux, Dirk Eddelbuettel has led a packaging effort such that
"apt-get install libopenmpi-dev openmpi-bin" (or the equivalent from
aptitude or synap
Hi,
Can you give more info about the compilation steps, I just recompiled it
(using the internal stuff except for fftw) and was able to run an
example (output below). Did I miss something ?
I recompiled / ran on a Platform OCS 5 cluster (based on RHEL 5), with
IB support (OFED)

Yes, I run it on my dual core apple notebook.

Hi Anugraha, Jody, Mohd, and list
Anugraha: You should follow Jody's recommendation.
Read the OpenMPI FAQ, particularly the ones on how to install OpenMPI
compile, and run programs.

All,
I had a similar problem as James described in an earlier message:
http://www.open-mpi.org/community/lists/users/2008/07/6204.php
While he was able to recompile openmpi to solve the problem, I had no luck
with my RedHat Enterprise 5 system.
Here are two other threads with similar issues regard

I have a HP Compaq Notebook with dual core processor.Can i use MPI in
this?For learning purpose?
Hi Terry (and others),
I have previously explored this some on Linux/X86-64 and concluded that
Open MPI needs to supply it's own memcpy routine to get good sm performance,
since the memcpy supplied by glibc is not even close to optimal.
We have an unused MCA framework already set up to supply an op

Hi Anughra

It answers may questions and also provides instruction to install
Open-MPI and build MPI applications.
And, yes, Open-MPI works with gcc.
