Re: [OMPI users] Randomly long (100ms vs 7000+ms) fulfillment of MPI_Ibcast

2014-11-06 Thread Rolf vandeVaart
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 four nodes? Also, in your original message you wrote "Likewise, it doesn't matter if I enable CUDA support or not.

I was hoping our CUDA person would respond, but in the interim - I would suggest trying the nightly 1.8.4 tarball as we are getting ready to release it, and I know there were some CUDA-related patches since 1.8.1 http://www.open-mpi.org/nightly/v1.8/ >

Dear Mr. Squyres, Thank you for your clear answer on the state of the interfaces in the mpi modules of OPENMPI. A good state! And I have coded sufficiently bugs myself, so I do not become too angry about the bugs of others. If I should stumble upon missing Ftn-bindings in the future, I will

Dear Mr. Squyres, I agree fully with omitting the explicit interfaces from mpif.h . It is an important resort for legacy codes. But, in the mpi and mpi_f08 module explicit interfaces are required for all(!) MPI-routines. So far, this is not fulfilled in MPI-versions I know. I want to

Andrew, Thanks. We're using the RHEL version because it was less complicated for our environment in the past, but sounds like we might want to reconsider that decision. Do you know why we don't see the message with lower node count allocations? It only seems to happen when the node count gets

Dear Mr. Squyres, a) When looking in your mpi_sizeof_mpifh.f90 test program I found a little thing: You may (but need not) change the name of the integer variable size to e.g. isize , because size is just an intrinsic function in Fortran (you may see it already, if you have an
