Changes to MPI Forum Trac
by Jeff Squyres 28 Oct '09

28 Oct '09

The Indiana U. admins have slightly changed how we login to the MPI Forum Trac / wiki. The next time you login to the Forum wiki pages, you will be prompted to verify your email address. You'll receive an email with a trivial click-through procedure. ***You will not be able to do anything on Trac/wiki until you verify your email address.*** You'll notice that the Trac login and "I forgot my password" screens are slightly different than they used to be. The reasons why this was done are technical and uninteresting. Please let me know if you have any questions or problems. -- Jeff Squyres jsquyres(a)cisco.com

I've made reservations for the hotel. I'm not sure if it came out of the MPI Forum room block though. I mentioned MPI Forum and asked for the government rate. Should I call the hotel back and make sure I get put on the MPI Forum list? -craig On Sep 28, 2009, at 7:48 AM, Graham, Richard L. wrote: > There is a room block that will be available Tuesday to Friday night > the week of the MPI Forum.

Since we are just proposing to deprecate MPI_Dims_create and not actually removing it, improvements to it might still be useful -- might not be from a user's standpoint, but from an MPI implementation's standpoint for applications/libraries that are already using it. > Could we just deprecate MPI_Dims_create and replace it > with a new function that serves the exact same purpose > but also has a communicator argument?

I'm not sure how the user can fine-tune the values returned by the Dims_create function without losing out on the "topology-awareness". If there is a need for it, we should certainly consider adding a new function. But I don't see a concrete advantage in doing so. > I gues the other changes to MPI_Cart_create would still > be needed but do not necessarily eliminate the need for > the manual process. Agreed. We don't disallow the user from manually providing the dimensions (similar to MPI-2.2). So, most applications using MPI-2.2 should almost automatically work correctly with this change. But at the same time, it might be easier to just get rid of the manual part if an application wants. Thanks, -- Pavan -- Pavan Balaji http://www.mcs.anl.gov/~balaji

Pavan: The basic goal -- improving the usability of Cartesian communicators -- is definitely worthwhile. The specific proposals seem reasonable; I might tweak the wordings... Are the two proposals mutually exclusive? One seeks to improve MPI_Dims_create while the other proposes to deprecate it. It seems like we should go one way or the other but not both. I suppose we could enact both if we omit part one (the deprecation) of the second. Could we just deprecate MPI_Dims_create and replace it with a new function that serves the exact same purpose but also has a communicator argument? I seem to recall that the idea was that sometimes the user either needs to do some data movement prior to the communicator creation or might want to fine-tune the results that MPI_Cart_create would otherwise provide... I gues the other changes to MPI_Cart_create would still be needed but do not necessarily eliminate the need for the manual process.
