MPI_Ibcast
The CUDA person is now responding. I will try and reproduce. I looked through
the zip file but did not see the mpirun command. Can this be reproduced with
–np 4 running across fo
ort or not. " Can you provide more detail about what that
means?
Thanks

Hello,
We were using OpenMPI for some testing, everything works fine but randomly,
MPI_Ibcast()
takes long time to finish. We have a standalone program just to test it. The

is the profiling results of the simple test program on our cluster:
Ibcast 604 mb takes 103 ms
Ibcast 608 mb ta
