There's nothing wrong with that fix, other than it shouldn't be necessary. The nonblocking routines in MPI are present to avoid the need for large buffering requirements and to avoid unnecessary buffer copying; an implementation should exploit this. I suspect that there is some simple oversight in the BG/L code that can be adjusted for such large receive buffers.As I said a week or so ago on this issue, when I had a similar (I think it was rather similar) problem, I was told to use MPI_SSEND which completely fixed the problem. Is there something wrong with that fix here?
