In my network i have some 32 bit machines and some 64 bit machines.
With --host i successfully call my application:

Called this way

The majority of processes get stuck in MPI_Barrier.
My Test application looks like this:

int iResult = 0;

This worked for me although I am not sure how extensive our 32/64
interoperability support is. I tested on Solaris using the TCP
interconnect and a 1.2.5 version of Open MPI. Also, we configure with
the --enable-heterogeneous flag which may make a difference here. Also
this did not work fo
Rolf,
I was able to run hostname on the two noes that way,
and also a simplified version of my testprogram (without a barrier)
works. Only MPI_Barrier shows bad behaviour.
Do you know what this message means?

On a CentOS Linux box, I see the following:

#define EHOSTUNREACH113 /* No route to host */
I have also seen folks do this to figure out the errno.

No route to host at -e line 1.

Hi,
I found an archive email with the same basic error I am running into for
mpi 1.2.6, unfortunately other then the question and request for the
output, there was not an email response on how it was solved.

Hi,
If I configure openmpi with "-enable-mpi-profile" option:
1) Once build is complete, how do I specify profile name and
location in the "mpirun" command? Do I have to set any flags with the
"mpirun" command to view profile?
2) If vampire trace by default is built with openmp

was nothing to do.
I think you're expect something that the MPI profiling interface is
not supposed to provide you. There is no tool to dump or print any
profile information by default (and it is not mandated by the
standard). What this option does, is compile the profiling interface

Well, as a quick hack, you can try adding --disable-dlopen to the
configure line. It will disable the building of individual components
(instead linking them into the main shared libraries). It means that you
have to be slightly more careful about which components you build, but in
practice u
But if openmpi is installed, I can automatically instrument my
application with Vampir (ie I don't have to install vtf separately -
right?)
And I can view with Vampir Trace the results of my app's parallel run?

Thanks Rueti. It works now. I just disabled firewall on all machines
since Open-MPI uses random port each time.
Thanks again!

Hi all,
I have a Cluster with Torque and PVFS. I'm trying to test my
environment with MPI-IO Test but some segfault are occurring.
Does anyone know what is happening ? The error output is below:

Thanks to those who answered my post in the past. I have to admit that you lost

I was able to get 2 of my systems cranked up and was about to put a third
system online when I remembered it was running x64 version of OS.

Open MPI can manage heterogeneous system. Though you prefer to avoid
this because it has a performance penalty. I suggest you compile on
the 32bit machine and use the same version everywhere.

Thanks for the information. I'll try it out.
