Hi All,

Below is the rationale and advice to users that we discussed today.

 ~Jim.

Rationale

MPI libraries may have implementation specific mechanisms (e.g.,
environment variables) that control the supported memory allocation kinds.
The implementation-defined behavior of “default” provides compatibility
with such mechanisms.

Advice to Users

Applications are encouraged not to rely on the implementation-defined
behavior of the “default” memory allocation kind.
