Hi all,
I want to get the elapsed time from start to end of my parallel program
(OPENMPI based). It should give same time for the same problem always;
irrespective of whether the nodes are running some or programs or they are
running only that program. How to do this?
Regards.

The problem has to do with how plugins (aka dynamic shared objects,
DSO's) are loaded. When a DSO is loaded into a Linux p
Hi
I'm not sure if i completely understand your requirements,
but have you tried MPI_WTime?

Hi!
The following code shows a bad behaviour when running over openib.
Openmpi: 1.3.3
With openib it dies with "error polling HP CQ with status WORK REQUEST
FLUSHED ERROR status number 5 ", with tcp or shmem it works as expected.
#include

#include "mpi.h"

Aha - this might also explain what I faced some time ago. I tried to
compile an application called Molpro with GlobalArrays which I
compiled with Open MPI. I faced simil
Hi, how exactly do you run this to get this error? I tried and it
worked for me.

Cisco is no longer an IB vendor, but I seem to recall that these kinds
of errors typically indicated a fabric problem. Have you run layer 0
and 1 diagnostics to ensure that the fabric is clean?

Hi Everyone,
I wrote a small program with a function to trigger the
checkpointing mechanism as follows:
#include

void trigger_checkpoint();
int main(int argc, char **argv)
{
int rank,size;

Oops. Red Face big time.
I happened to run the IB test between two systems that don't have IB
connectivity.
Goes and hide in a dark corner...

Hi Everyone,
I noticed that it hangs just before displaying the following

I've built openmpi version 1.3.3 on a MacPro with OS X 10.5.8 and the Intel 10.1.006 Fortran compiler and gcc 4.0. As far as I can tell, the configure and make commands completed fine. There are some warnings, but it's not clear to me that they are critical - or the explanation for what's not work
Hi Ralph,
Thank you for you help. This is exactly what I wanted!

Hmmm...well, here is one way to do it:
mpirun -n 1 -host n0 ./master_worker : -n N-1 -host +e ./master_worker
What this will do is put rank 0 on the first node in your allocation,
and then

Andreas,
Have you checked that ifort is creating 64 bit objects. If I remember
correctly with 10.1 the default was to create 32 bit objects.
