Hi all, We had a formal reading at this week's MPI forum in Chicago. We did get a lot of feedback and, while many comments were focusing on grammar and language, we also had a few more technical issues which were considered not ticket 0: - The naming issue came up. The single "T" wasn't received well, but people could live with it, if alternatives (like MPI_Tools) are too long (I'll see what fits). If you have ant good ideas what could be there instead of Tools please let me know. - Either way, to conform with MPI naming conversion, we need to change the first upper case letter to lower case, i.e.: MPI_T_Cvar_get_info we need MPI_T_cvar_get_info - One comment was that the things measured by the Pvar interface are almost entirely (all?) unsigned values and hence we should switch to unsigned data types (or at least include them). Also, we should include MPI_LONG. - Some people (especially for platforms with lean OSes) didn't like the signal safety text - I will create a rewrite and send that around for discussion - It was suggested to add a "non-atomic" flag to Pvar_get_info to identify variables that are cannot be passed to Pvar_readreset. I will update the text to reflect these comments (in the next 1-2 weeks) and will send that around. After that we will arrange a phone call to go over any open issues. If there are any comments on the issues raised before that, please let me know. Thanks, Martin
