MPI One-Sided Communication
by Simone Atzeni 23 Apr '09

23 Apr '09

Hi, I'm an italian student and I'm doing a thesis about Formal Verification. Now, I'm looking for information about mpi one-sided communication to see who uses one-sided and for what (user applications or implementing library). My target would be to implement a software to do model checking on mpi one-sided communication programs. But before begin my work, I'd like to know if this can be useful in the scientific world or if mpi one-sided communications is an obsolete standard doesn't use anymore, so it could be a work not much useful. I'd like to hear your idea about this topic. Sorry for my bad english, I hope that you understand me. Thanks for your attention. Simone

Most of the resources are now in place to support the newly formed Active Messages working group. Darius Buntinas from Argonne National Laboratory is leading the effort. There appears to a problem with the mailing list it is working but can¹t sign up for it but this should be fixed in the near term. Rich

Will be starting telecons for MPI3 Hybrid Programming Models
by Pavan Balaji 09 Apr '09

09 Apr '09

Hi all, We will be starting telecons to discuss tickets related to MPI 3 Hybrid programming (MPI + threads, MPI + UPC, etc). If you are interested in this, please subscribe to the mpi3-hybridpm(a)lists.mpi-forum.org mailing list here: http://lists.mpi-forum.org/mailman/listinfo.cgi/mpi3-hybridpm I'll be sending out a poll on that list for potential bi-weekly telecon times sometime next week. Thanks, -- Pavan -- Pavan Balaji http://www.mcs.anl.gov/~balaji

Re: [Mpi-forum] MPI prototype license

I think the Forum should make it clear that a reference implementation may not carry a GPL license. Any GPL like license would greatly restrict the number of people who could evaluate the implementation Dick Treumann - MPI Team IBM Systems & Technology Group Dept X2ZA / MS P963 -- 2455 South Road -- Poughkeepsie, NY 12601 Tele (845) 433-7846 Fax (845) 433-8363 mpi-forum-bounces(a)lists.mpi-forum.org wrote on 04/03/2009 03:17:58 PM: > [image removed] > > Re: [Mpi-forum] MPI prototype license > > Jeff Squyres > > to: > > Main MPI Forum mailing list > > 04/03/2009 03:21 PM > > Sent by: > > mpi-forum-bounces(a)lists.mpi-forum.org > > Please respond to Main MPI Forum mailing list > > On Apr 3, 2009, at 3:04 PM, Supalov, Alexander wrote: > > > Many prototypes are being developed currently for MPI-2.2 and MPI-3. > > Under what license will they be made available to the community? > > Certain types of licenses, like GPL, may not be suitable for > > commercial adoption of the prototype code.

I second Alexander's request. For me GPL is a no-no and my legal department would prevent me from looking at any GPL source code; thus preventing me from reviewing any such code for the MPI forum. The legal department would grant me permission to look at BSD licensed code after consulting with them. This is regardless of integration to any Microsoft product.

I guess that raises the meta question -- what is the intent? Is it a requirement that the proof-of-concept open source implementations must be licensed such that, in practice (not theory) they can be slurped into commercial/closed source MPI implementations? Or is it enough that some people implemented it, some [other] people reviewed it, and the union of those people have said "yes, this shows what we want it to show"? (and potentially a 3rd set of people who didn't look at the proof-of-concept implementation go re-implement it in their MPI implementation) I thought the intent was to show that the concept was possible and to help unearth any "gotchas" in terms of implementation that might not be thought of during the design phase. But to be clear: OMPI, where I have done all my implementation work for MPI 2.2 tickets, is BSD (IANAL, and none of this is legal advice -- go read our license yourself) so I don't really care too much. -- Jeff Squyres Cisco Systems _______________________________________________ mpi-forum mailing list mpi-forum(a)lists.mpi-forum.org http://lists.mpi-forum.org/mailman/listinfo.cgi/mpi-forum

I would support such a discussion and also propose a BSD-like license. Another interesting question: what license is MPI-2.1 under?

MPI prototype license
by Supalov, Alexander 03 Apr '09

03 Apr '09

Hi everybody, Many prototypes are being developed currently for MPI-2.2 and MPI-3. Under what license will they be made available to the community? Certain types of licenses, like GPL, may not be suitable for commercial adoption of the prototype code. BSD-like licenses are normally acceptable. I think we should discuss this matter at the Forum this time. You comments and suggestions are welcome. Best regards.
