[OMPI users] parallel I/O on 64-bit indexed arays

Hello! The problem I face is not open-mpi specific, but I hope still the MPI wizards on the list can help me nonetheless. I am running and developing a large-scale scientific code written in Fortran90. One type of objects are global 1-D vectors, which contains data for particles in the

Re: [OMPI users] Program hangs when using OpenMPI and CUDA

Hi Fengguang: That is odd that you see the problem even when running with the openib flags set as Brice indicated. Just to be extra sure there are no typo errors in your flag settings, maybe you can verify with the ompi_info command like this? ompi_info -mca btl_openib_flags 304 -param btl

Hi Rolf, I double checked the flag just now. It was set correctly, but the hanging problem is still there. But I found another way to solve the hanging problem. Just setting environment CUDA_NIC_INTEROP 1 could solve the issue. Thanks, Fengguang On Jun 6, 2011, at 10:44 AM, Rolf vandeVaart

Yes -- check out the README; there's a section on MTLs vs. BTLs. If that's not clear, post back here and we can explain further (and update the README :-) ). On Jun 4, 2011, at 10:15 AM, amjad ali wrote: > Hello all, > > the FAQ page about using myrinet >

If I understand your question correctly, this is *exactly* one of the reasons that the MPI Forum has been arguing about the use of a new type, "MPI_Count", for certain parameters that can get very, very large. - Sidenote: I believe that a workaround for you is to create some new MPI
