Dear all

I think I already read some comments on this issue, but I'd like to know of latest versions of OpenMPI have managed to solve it. I am now running 1.2.5

If I run a MPI program with synchronization routines (e.g. MPI_barrier, MPI_bcast...), all threads waiting for data are still burning CPU. On the other hand when using non-blocking receives all threads waiting for data are not consuming any CPU.

Would there be a possibility to use MPI_Bcast without  burning CPU power ?

Thanks in advance

Vincent
