Hi,
I was just wondering what does "progress: no" signify when I check the level
of thread support using ompi_info for the OpenMPI installation I have.
Also, I guess "mpi: no" for thread support signify that multiple threads in
my MPI program will not work as expected if they have MPI communicati

Hi there!
In my code I use MPI_Comm_accept in a server-client communication. I noticed
that the server remains on busy wait whereas waiting for clients
connections, using 100% of CPU if there are no other processes running.
I wonder if there is any way to prevent this from happening.
Thanks in a
All,
I'm using OpenMPI 1.4.3 and have been running a particular case on 120, 240,
480 and 960 processes. My time-per-work metric reports 60, 30, 15, 15. If I
do the same run with MVAPICH 1.2, I get 60, 30, 15, 8. There is something
running very slowly with OpenMPI 1.4.3 as the process count g
Okay so I finally have a matching set of debug openmpi installs. Here is
