Re: [Mpi-21] Implementation of MPI-2.1

Hi everybody, I'm going to miss this meeting, so let me use this reply as a chance to express my opinion ahead of the vote: - We need to produce official versions of the MPI-1.3 and MPI-2.1 documents with change mark-up, either in change bars or in color coding. At the moment, as far as I understand, only the official documents are going to be published, and they won't have clear indication, apart from the MPI-2.1 change log, of what was actually changed in the text. Many standard bodies I know routinely publish marked-up versions of their new documents to facilitate smooth transition. If we don't follow this practice, we risk implementors overlooking some small but important changes, and then claiming MPI-1.3 and MPI-2.1 compliance by mistake. - The desire to have only Forum members edit the standards is a good one, but it may not be practical. In the particular case of the language binding Annex, we'd not be able to complete the massive chances on time without delegating this to someone else. This would make the standard process slip, which was considered a bigger risk at the time. What is necessary here is rather more careful supervision and review of the results, which I think we should take into account going forward. - If there are any material changes needed to Intel MPI implementation to make it MPI-1.3 and MPI-2.1 compliant, we'll target 2009. If we can claim MPI-1.3 and MPI-2.1 compliance in the current code without noticeable changes, either to the code or to the current draft during the pending voting, we may decide to go for this year's fall release. Best regards.

Re: [Mpi-21] running MPI only in a single function
by unknown＠example.com 03 Jun '08

Greetings Vishal. This list is not really for user-level questions about MPI; it is for the standards committee itself to discuss issues related to the upcoming MPI-2.1 standard. You might want to google around for various MPI tutorials and/or textbooks. Many of them address exactly this kind of topic. Good luck!

running MPI only in a single function
by unknown＠example.com 03 Jun '08

03 Jun '08

Dear All I am trying to parallelize my code using MPI. My problem is i want to run several processes only in one of the functions of my C++ code (not in main). Basically my code is divided into several functions. And in one of the functions i want to parallelize. How can I do that using MPI............. -- Regards *********************************************** Vishal Agarwal Research Scholar *********************************************** *
