Hi Ryan,
<div class=""><br class="">
</div>
<div class="">Here are my notes from the WG meeting today:</div>
<div class=""><br class="">
</div>
<div class=""><br class="">
Define channel - for all usages throughout the spec (existing and proposed).<br class="">
<br class="">
Example: use variables for tag, dest, etc parameters in the Psend_init call<br class="">
Example: use variables for tag, dest, etc parameters in the Precv_init call<br class="">
<br class="">
Example: typo for MPI_Pstart - should be MPI_Start and should not end with brace<br class="">
<br class="">
Example: typo for &xfer_type in the Psend_init call - use just xfer_type instead<br class="">
Example: typo for &xfer_type in the Precv_init call - use just xfer_type instead<br class="">
Example: typo for &request and &i in the Pready call - use just request and i instead<br class="">
Example: typo for &part in the Pwait call - use just part instead<br class="">
<br class="">
Question: can partitioned receive match with any other send than the partitioned send it matched with during initialisation? No.<br class="">
<br class="">
Question: how does datatype describe complex layouts?<br class="">
Answer: it does not - it is the same as I/O with eType == xfer_type and fileType == contig<br class="">
<br class="">
Suggestion: add an MPI_Info parameter to both MPI_Psend_init and MPI_Precv_init<br class="">
<br class="">
Example: typo for amp parallel for (the for is missing)<br class="">
<br class="">
Example: tasks need to use different values for i in Pready<br class="">
<br class="">
Suggestion: mandate exactly one call to Pready for each partition between start and wait<br class="">
<br class="">
Suggestion: partition parameters must be consistent - either int or MPI_Count</div>
<div class=""><br class="">
</div>
<div class="">Note: there is room for (and potential use-cases for) Psendv_init (Pavan’s case) and Psendw_init (Rich’s case)<br class="">
