<p><font size="2" face="sans-serif">Last time we discussed these, I thought there were going to be some minor changes made. Unfortunately, these revised texts seem to have significant changes, and are farther from what I was comfortable with. We don't seem to be converging on a target. Here's what I've been thinking:</font><br>
<br>
<font size="2" face="sans-serif">* One MPI_INIT (or MPI_INIT_THREAD) and one MPI_FINALIZE per OS process. After MPI_INIT*, all MPI Processes are initialized.</font><br>
<br>
<font size="2" face="sans-serif">* Every thread is associated with one MPI Process by default. Which MPI Process is implementation defined. A call to MPI_COMM_RANK on MPI_COMM_WORLD will tell which. (sub-communicators might return MPI_PROC_NULL)</font><br>
<br>
<font size="2" face="sans-serif">* changing associated is permitted with MPI_THREAD_ATTACH (not sure I'm comfortable with the abstract "index" version of this, I like (MPI_COMM, rank) more)</font><br>
<br>
<font size="2" face="sans-serif">* No new thread levels. Specify that thread level is relative to the MPI Process. I'm OK with requiring that multiple MPI processes requires thread level > MPI_THREAD_SINGLE, although I'm not sure it is necessary.</font><br>
<br>
<font size="2" face="sans-serif">MPI_COMM_SPLIT_TYPE is fine as-is, I think.</font><br>
<br>
