I understand. But then I think your UDP comparison is wrong - whatever... :)

Hello Mudassar,
I think you want an "asynchronous communication".
Therefore you could use these functions:

Best regard
Hello Ralph and thanks for your answer!

It was installed in the default path which is chosen by OFED.
And yes, I've edited the right openmpi-default-hostfi
Hello together!
I've built v1.4.3 (which was in OFED-1.5.3.2) and v1.4.4 (from you website).
But in both versions I've the following problem:
If I write some hosts into
'/usr/mpi/gcc/openmpi-1.4.4/etc/openmpi-default-hostfile':
cluster1
cluster2
cluster3
cluster4
and execute 'mpirun -np 4 " then
