Re: [OMPI users] [Fwd: mpi alltoall memory requirement]

You may try to use XRC, it should decrease openib btl memory footprint, especially on multi-core system, like you have. The follow command will switch default OMPI config to XRC: " --mca btl_openib_receive_queues X,128,256,192,128:X,2048,256,128,32:X,12288,256,128,32:X,65536,256,128,32" Regard
