The short version: other MPI's allow it (LAM/MPI, CT6, MPICH2)
|
|
probably mainly because the Intel MPI test suite expects it to
|
|
happen and there's now several years worth of expected behavior
|
|
to allow this behavior. Rather than have to explain every time
|
|
why OMPI is the only one who completely adheres to the standard
|
|
/ fails the intel tests, it seemed easier to just let this one
|
|
slide. It's not really that important, after all! */
