Folks, If an application has multiple sessions and does a PVAR_START on all sessions, is the intention that the MPI implementation will keep track of each pvar on each of the sessions? Since when the pvar_start is called for each session is different, the values of these variables can be different. So is the MPI implementation expected to replicate these variables per session? Is this true for the read-only ones as well, since the start time can be different for each session? -- Pavan -- Pavan Balaji http://www.mcs.anl.gov/~balaji
