- broadcasts list contiguous content as a two-step process: 1. broadcast the size, and resize for receiver list 2. broadcast contiguous contents (if non-empty) This avoids serialization/de-serialization memory overhead but at the expense of an additional broadcast call. The trade-off of the extra broadcast of the size will be less important than avoiding a memory peak for large contiguous mesh data. REVERT: unstable MPI_Mprobe/MPI_Mrecv on intelmpi + PMI-2 (#2796) - partial revert of commit c6f52858, for NBX implementation. Not yet flagged as causing errors here, but eliminated for consistency.
