+ - TIT (Time Independent Traces): We finally support tags. Unfortunately,
+ this means that traces now need to be updated or re-obtained; both Irecv
+ and Isend lines in your traces have now in total 5 mandatory fields:
+ <rankid> <command> <to/from rankid> <tag> <size>
+ To update your traces, it suffices to add a 0 for the tag here.
+ - TIT now also supports waiting for a distinct request via MPI_Wait.
+ Wait/Test now wait for a specific request, not just the last one that was
+ issued. This unfortunately means another update, because we need to
+ identify which request you want to wait for. We do this via the
+ triplet (sender, receiver, tag), which needs to be added:
+ <rankid> <command> <sender> <receiver> <tag>
+
+MSG
+ - The deprecation of MSG is ongoing (but this should not impact you).
+ Many MSG functions are now simple wrappers on the C API of S4U. If
+ you wish to convert your code to S4U, find the S4U counterparts of
+ your MSG calls in src/msg/msg_legacy.cpp.
+ - MSG can still be used, but won't evolve anymore.
