Hello,

  I'm using the PERUSE API from OpenMPI in order to know when messages
arrive. I've executed some simple tests in three different machines
(FreeBSD/x86 1cpu, SGI Altix/IA64 128cpus, Linux/ppc 4cpus) always using
OpenMPI 1.2 and I see that sometimes I'm loosing such MSG_ARRIVED events.

  For example, from the 20 runs that I do, 5 at least, do not show that
every task but the root prints "total_msg_arrived = 1", instead they
print some "total_msg_arrived = 0".

  George Bosilca told me that this never should happen due to the code
implementation, but it's happening to me. So I'm wondering why is this
happening in all the machines. Any idea?

  I run the configure just with the --prefix option and with
- --enable-peruse. Shall I add any other option?

Regards,
