Re: [OMPI users] Segmentation fault when Send/Recv on heterogeneouscluster (32/64 bit machines)

can send big array with small "btl_tcp_eager_limit" from a 64bit machine to a 32bit one. Do I have to move this thread to devel mailing list ? Regards, TMHieu On Tue, Mar 2, 2010 at 2:54 PM, TRINH Minh Hieu wrote: > Hello, > > Yes, I compiled OpenMPI with --enable-heterogeneous. More preci

[OMPI users] Segmentation fault when Send/Recv on heterogeneous cluster (32/64 bit machines)

Hello, I have some problems running MPI on my heterogeneous cluster. More precisley i got segmentation fault when sending a large array (about 1) of double from a i686 machine to a x86_64 machine. It does not happen with small array. Here is the send/recv code source (complete source is in att
