We had a short discussion on the call today but decided to reschedule to
next week, April 1, 9am US Central Time. The connection info will be the
same as today, found in the wiki links below.
Topics we would like to discuss:
* How can application specify devices in MPI?
* Introduction of a query mechanism for device IDs through MPI_INFO_ENV.
* ABI issues when supporting device-side MPI function calls.
* Portability issues at compile-time and runtime between different
implementations supporting device bindings.
* Memory space specification for allocation functions (see
