IMB 4.0 bug report with RMA side

Mingzhe_L_ — Wed, 27 Nov 2013 00:07:00 GMT

Hi Sir/Madam,

When I was running the latest IMB 4.0 which supports MPI-3 RMA, I found an issue with the benchmark. The benchmark didn't call MPI_Win_free to free the window when the benchmark exits. The following code is where MPI_Win_free is called inside IMB 4.0. It is called only for IMB-EXT, not for IMB-RMA. It seems to be a bug in the benchmark. Could you give me some feedbacks about this?

#ifdef EXT

if( c_info->WIN != MPI_WIN_NULL )
MPI_Win_free(&c_info->WIN);

#endif /*EXT*/
