REDUCE_SCATTER to more thoroughly check the datatype/op combination to see if it's valid or not. If it's not, print a meaningful error message rather than "Invalid MPI_Op" indicating what specifically was wrong (therefore hopefully helping users track down where in the code the problem is, and/or telling us that there's a reduction operation combo that we don't support that we should) - The check for whether a datatype is intrinsic needed to be updated -- it's not sufficient to check that dtype->id < DT_MAX_PREDEFINED; you really need to check the PREDEFINED flag on the datatype. Thanks to George for this fix (only intrinsics have a meaningful value in dtype->id). This commit was SVN r7923. |
