Is it possible to get a build of 3.0rc1 for Windows 32bit and 64bit? I would like to test my updates to mpi4py on these platforms. -- Lisandro Dalcin --------------- CIMEC (INTEC/CONICET-UNL) Predio CONICET-Santa Fe Colectora RN 168 Km 472, Paraje El Pozo 3000 Santa Fe, Argentina Tel: +54-342-4511594 (ext 1011) Tel/Fax: +54-342-4511169

Hi Lisandro, As always, thank you for your thorough testing and concrete test cases. I don't think anyone has time to look at this right away, but I've created a ticket for it so that we don't lose track: http://trac.mcs.anl.gov/projects/mpich2/ticket/1755 Best, -Dave On Nov 19, 2012, at 1:12 PM CST, Lisandro Dalcin wrote: > I understand external32 support is not fully implemented, but anyway I > want to raise your attention on this inconsistency.

MPI_Pack_external() with "long" and "double"
by Lisandro Dalcin 19 Nov '12

19 Nov '12

I understand external32 support is not fully implemented, but anyway I want to raise your attention on this inconsistency. See the attached file for code (BTW, I'm using 3.0rc1). Using "long", I get: $ ./a.out Conversion of types whose size is not the same as the size in external32 is not supported Aborting with internal error However, using "double", the call succeed, but a pack->unpack roundtrip gives bad results: $ ./a.out a.out: pack-ext32.c:42: main: Assertion `input==output' failed. Aborted (core dumped) Plese fire up a debugger for the latter case and check the value of "input" before and after the unpack call, I'm not sure what's going on. -- Lisandro Dalcin --------------- CIMEC (INTEC/CONICET-UNL) Predio CONICET-Santa Fe Colectora RN 168 Km 472, Paraje El Pozo 3000 Santa Fe, Argentina Tel: +54-342-4511594 (ext 1011) Tel/Fax: +54-342-4511169

I haven't confirmed this yet, but I'm not filing a bug because perhaps this instead should be the subject of an MPI-3 erratum discussion. For those who - like me - (didn't) don't know what "horks" mean, I recommend that you do not Google it. The definition from urbandictionary.com is quite foul.

Announcing the availability of MPICH 3.0rc1
by Pavan Balaji 13 Nov '12

13 Nov '12

The MPICH team is pleased to announce the availability of the first release candidate (rc1) in the new major release series (mpich-3.0). http://www.mpich.org/ MPICH-3.0rc1 is the first preview of a major feature release. The primary focus of this release is to provide full support for the MPI-3 standard. But other features including support for ARM v7 native atomics are also included. This is a feature-preview release. MPICH2 developers, testers and other advanced users are encouraged to try this release out and let us know if you encounter any problems. This release is not intended for production systems at this time; such systems should continue to use the latest release from the 1.5.x branch (currently 1.5). The major additions in the 3.0rc1 release are highlighted below. Regards, The MPICH Team =============================================================================== Changes in 3.0rc1 =============================================================================== # MPI-3: All MPI-3 features are now implemented and the MPI_VERSION bumped up to 3.0. # OVERALL: Added support for ARM-v7 native atomics # MPE: MPE is now separated out of MPICH and can be downloaded/used as a separate package. # Several other minor bug fixes, memory leak fixes, and code cleanup. A full list of changes is available using: svn log -r10344:HEAD https://svn.mcs.anl.gov/repos/mpi/mpich2/tags/release/mpich-3.0rc1 ... or at the following link: https://trac.mcs.anl.gov/projects/mpich2/log/mpich2/tags/release/mpich-3.0r… -- Pavan Balaji http://www.mcs.anl.gov/~balaji
