[OMPI users] error building openmpi-dev-685-g881b1dc on Soalris 10

Hi, today I tried to build openmpi-dev-685-g881b1dc on my machines (Solaris 10 Sparc, Solaris 10 x86_64, and openSUSE Linux 12.1 x86_64) with gcc-4.9.2 and the new Solaris Studio 12.4 compilers. I succedded on Linux but failed on both Solaris systems for both compilers with the same error. ...

Re: [OMPI users] Segmentation fault when using CUDA Aware feature

That is strange, not sure why that is happening. I will try to reproduce with your program on my system. Also, perhaps you could rerun with –mca mpi_common_cuda_verbose 100 and send me that output. Thanks From: users [mailto:users-boun...@open-mpi.org] On Behalf Of Xun Gong Sent: Sunday,

Re: [OMPI users] Segmentation fault when using CUDA Aware feature

I think I found a bug in your program with how you were allocating the GPU buffers. I will send you a version offlist with the fix. Also, there is no need to rerun with the flags I had mentioned below. Rolf From: Rolf vandeVaart Sent: Monday, January 12, 2015 9:38 AM To: us...@open-mpi.org

Re: [OMPI users] MPI_Type_Create_Struct + MPI_TYPE_CREATE_RESIZED

Jeff, thanks for all the good catches. MPI_Type_create_resized is not required in this example because send/recv are called with count=1. Generally speaking, if count > 1, MPI_Type_create_resized is required because the compiler might add some padding at the end of the type. Cheers, Gilles
