[OMPI users] MPI symbols invoked from PMPI calls?

2015-11-06 Thread Harald Servat
Dear all, we develop an instrumentation package based on PMPI and we've observed that PMPI_Ibarrier and PMPI_Ibcast invoke regular MPI_Comm_size and MPI_Comm_rank instead to the PMPI symbols (i.e. PMPI_Comm_size and PMPI_Comm_rank) in OpenMPI 1.10.0. I have attached simple example that d

Cristian, you might observe super-speedup heres because in 8 nodes you have 8 times the cache you have in only 1 node. You can also validate that by checking for cache miss activity using the tools that I mentioned in my other email. Best regards. On 22/07/15 09:42, Crisitan RUIZ wrote:

Dear Cristian, as you probably know C class is one of the large classes for the NAS benchmarks. That is likely to mean that the application is taking much more time to do the actual computation rather than communication. This could explain why you see this little difference between the two
