[mpiwg-persistence] Summary of Semantics for Partitioned Communication Operations

Hi All, I was planning to bring this topic at today's meeting. Since we did not meet, I would like all of you to review the attached spreadsheet and complete the corresponding columns for stages, completion, blocking/nonblocking, type of operation, and resources blocked/comment. I have copied the persistent point-to-point section of the table and used it as a starting point. Please review and let me know what you all think. For the operation column, I have entered ?-op. Do we need to define "pp-op" to denote partitioned communication operation? I have added a footnote that indicates the difference between persistent initialization functions and partitioned initialization functions. Thanks, Puri
