There are 2 things addressed in this patch, one optimization and one correctness. 1. *correctness* the incorrect use of the rdtype on the step 3. A simpler fix would have...
I have another optimization that basically remove the need for the displ array. Instead of using MPI level functions to create the intermediary datatypes, it used OMPI capabilities to create...
There is one point that needs to be clarified: why we need to register our output files with PMIX.
Not for HAN. With the new accelerator framework I am not sure if this is still relevant.
Not perfect, but definitively better than before. Good to go from my perspective.
It was not clear from the comments what you were trying to achieve. Now that I understand better, it seems possible, but extremely unlikely to hit the scenario you describe....
Yes, you need to manipulate the filename string a little, because it might contain separators and/or might be too long. But is can give you a nice base for uniqueness....
The BTLs are an easy target for discussion because they are obviously not necessary when not running an MPI job, but the issue remains true for many other shared libraries...
