Here are some items that are perhaps suitable for MPI-2.2 * MPI_Reduce_scatter_block * (possibly) built-in segmented Scan operations (new binary operators) * Correction/clarification to semantics of one-sided synchronization when switching between modes (NOTE: the proposal I posted some months back is deficient, as Rolf pointed out to me, and will have to be modified) I will try to make final proposals before the next meeting Jesper On Mon, May 05, 2008 at 03:36:01PM -0500, Rajeev Thakur wrote: > Now that MPI 2.1 is close to completion, it is time to look at issues for > MPI 2.2.

I'd like to add a proposal for globalization (not localization). That is, adding to the standard text that defines all strings are UTF-8. (I'll put a proposal together for next meeting) A second proposal is to expose a Unicode (wchar_t) variation of all API's taking strings. However, that might be more suitable for 3.0.

Hi, May be we add a couple of calls to pass data back and forth between the client and MPI? Either assertions proposed by Dick Treumann, or more extensible (MPI_Info based?) approach proposed by Jeff Squyres? That's admittedly connected to subsets, but this is only an addition, no backward incompatible change. MPI 2.2? Best regards.

* Rajeev Thakur <thakur(a)mcs.anl.gov> [2008-05-05 15:36:01]: > * MPI_CHAR, MPI::CHAR should be signed char or char? In C and C++, char, signed char and unsigned char are all distinct types. (And in C++, wchar_t is yet another type; In C it is a typedef and thus not a new type but an alias) Char can either be signed or unsigned and this is platform/compiler dependent. So MPI_CHAR and MPI::CHAR should be whatever the compiler/platform thinks and cannot be fixed in the standard to be signed or unsigned. Dries

I have posted all the slides that people have sent to me, including some older slides from the January and March meetings, but I know that I'm still missing some from April. Please send them to me as soon as you can; thanks. On Apr 30, 2008, at 4:41 PM, Jeff Squyres wrote: > All -- > > Please send me your slides from the April Chicago meeting.
