Why don't you check the FAQ first:

It answers may questions and also provides instruction to install

And, yes, Open-MPI works with gcc.

Yuo must close the File using

By the way i think you shouldn't do

I once got different results when running on a 64-Bit platform instead of

platform only 64bit floats.

When you spawn processes with MPI_Comm_spawn(), one of the arguments

You can use this intercommunicator as the communicator argument

Hi Gabriele
In OpenMPI 1.3 it doesn't matter:
[jody@aim-plankton ~]$ mpirun -np 4 mpi_test5
aim-plankton.uzh.ch: rank 0 : MPI_Test # 0 ok. [3...3]
aim-plankton.uzh.ch: rank 1 : MPI_Test # 0 ok. [0...0]
aim-plankton.uzh.ch: rank 2 : MPI_Test # 0 ok. [1...1]
aim-plankton.uzh.ch: ra
a previous mail:
- call 'xhost +' for all nodes in my hostfile
- export DISPLAY=:0.0
- call
mpirun -np 8 -x DISPLAY --hostfile testhosts --xterm
--ranks=2,3,4,5! ./MPITest
combining --xterm with --output-filename also worked.
Thanks again!

Hi
In my application i use MPI_PROC_NULL
as an argument in MPI_Sendrecv to simplify the
program (i.e. no special cases for borders)
With 1.3 it works, but under 1.3.1a0r20520
i get the following error:
[jody@localhost 3D]$ mpirun -np 2 ./sr
[localhost.localdomain:29253] *** An error occurred in
Yes, it was doing no sensible work -
It was only intended to show the error message.
I now downloaded the latest nightly tarball and installed it,
and used your version of the test programm. It works -
*if* is use the entire path to mpirun:
[jody@localhost 3D]$ /opt/openmpi-1.3.1a0r20534/bin
Forgot to add.
i have /opt/openmpi/bin in my $PATH
I tried around some more and found that it
also works without errors if use
/opt/openmpi/bin/mpirun -np 2 ./sr
I don't understand this, because 'mpirun' alone should be the same thing:
[jody@localhost 3D]$ which mpirun
/opt/ope
Well all i do seems to verify that only one version is running:
[jody@localhost 3D]$ ls -ld /opt/openmp*
lrwxrwxrwx 1 root root 26 2009-02-13 14:09 /opt/openmpi ->
/opt/openmpi-1.3.1a0r20534
drwxr-xr-x 7 root root 4096 2009-02-12 22:19 /opt/openmpi-1.3.1a0r20432
drwxr-xr-x 7 root root 4096 2
parently i hadn't properly removed an old openmpi version which
had been put there by fedora...
Thanks!

I got this ssh message when my workstation wasn't allowed access because of the
settings in the files /etc/hosts.allow and /etc/hosts.deny on your ssh server.

A tu etabli que $PATH et $LD_LIBRARY_PATH contiennent les values correctes
quand tu fais une connexion ssh sans login?

bufcount is 0.

perhaps you could use the Open-MPI environment variables
OMPI_COMM_WORLD_RANK
OMPI_COMM_WORLD_LOCAL_RANK
to construct your own environment variables?
(for versions >= 1.3)

Hi
I don't understand why it is a problem to copy a single script to your nodes -
wouldn't the following shell-script work?
#!/bin/sh
for num in `seq 128`
do
scp new_script username@host_$num:path/to/workdir/
done

d i think you should add a "-n 4" (for 4 processors)
Furthermore, if you want to specify a host, you have to add "-host hostname1"
if you want to specify several hosts you have to add "-host
hostname1,hostname2,hostname3" (no spaces around the commas)

Hi
I don't understand the error messages, but it seems to me that your
open-MPI version (1.2.5) is rather old.
This might also explain the discrepancies you found in the documentation.
If you can do so, i would suggest you update your Open-MPI.

r all nodes.
Does anybody have experience in profiling parallel applications?
Is there a way to have profile data for each node separately?
If not, is there another profiling tool which can?
Thank You
Jody
ng subject would be worthy for a FAQ entry...
Thanks
Jody
