Bill, Thank you for the introduction. I am very excited to be on this project and look forward to working with you all. Regards, Kalyana Chadalavada On Feb 6, 2011, at 5:16 PM, Rajeev Thakur wrote:

Excellent! Welcome to all of you. I already know several of you.

Let us make sure the two groups remain in regular touch, perhaps even with regular biweekly phone calls. We are interested in some of these topics ourselves, such as the MPI-3 RMA work.

I'd like to make some introductions between the Illinois/NCSA group working on MPICH2 on POWER7 and the ANL group.

Kitrick Sheets - Is working on shared memory performance in Nemesis for Power7

Gopalakrishnan Santhanaraman - Is working on RMA enhancements, particularly the hybrid lazy/eager approach for passive target

Kalyana Chadalavada - Is working on MPI-3 updates, particularly the RMA chapter

(We are also collecting baseline performance data, on both the GA product and the upcoming system that is what will go into Blue Waters.)

Tarun Prabhu and Esteban Rojas have already been introduced; they continue to work on the LAPI (and eventually PAMI) port and will be looking at Datatype enhancements as well, as Torsten has found an application where datatypes provide a significant benefit.

Please welcome Kitrick, Gopal, and Kalyana and keep them in mind when looking at related parts of the code. Thanks!

Sure, but they'll need mcs accounts. If they have accounts, just send me their usernames, otherwise, have them fill out the form here: https://accounts.mcs.anl.gov/request.php You can list me as the sponsor/contact. If they're not US citizens, this may take a while, so it's better to do this sooner rather than later. -d On Feb 9, 2011, at 9:30 AM, Esteban Meneses-Rojas wrote:

Hi MPICH group. Kalyana, Tarun and I are working closely to debug, test and improve the LAPI port for MPICH2. Would it be possible to give Kalyana and Tarun read/write access to the LAPI branch? https://svn.mcs.anl.gov/repos/mpi/mpich2/branches/dev/lapi That would help us in having the right tool for continuing developing this MPICH2 port. Thanks.
