Hi Siegmar, We cannot reproduce this error on our test machines (Solaris i386, Ubuntu x86_64) by using your programs. And unfortunately we do not have Solaris Sparc machine thus could not verify it. Sometime, it can happen that you need to add "./" in front of the program path, could you try it ?

Hi Wahi, Do you mean you want to change number of hosts during one MPI execution? If so, we think that is not possible.

The MPICH team is pleased to announce the availability of a new preview release (mpich-3.2rc1). This is a release candidate of the upcoming MPICH 3.2. This preview release addresses a number of bugs that were present in previous releases. Unless other critical bugs are found, this release would be identical to the final 3.2 GA release (apart from the version number change). http://www.mpich.org <http://www.mpich.org/> A list of changes in this release is included at the end of this email. Regards, The MPICH Team =============================================================================== Changes in 3.2 =============================================================================== # Added support for MPI-3.1 features including nonblocking collective I/O, address manipulation routines, thread-safety for MPI initialization, pre-init functionality, and new MPI_T routines to look up variables by name. # Fortran 2008 bindings are enabled by default and fully supported. # Added support for the Mellanox MXM InfiniBand interface. (thanks to Mellanox for the code contribution). # Added support for the Mellanox HCOLL interface for collectives. (thanks to Mellanox for the code contribution). # Significant stability improvements to the MPICH/portals4 implementation. # Completely revamped RMA infrastructure including several scalability improvements, performance improvements, and bug fixes. # Added experimental support for Open Fabrics Interfaces (OFI) version 1.0.0. https://github.com/ofiwg/libfabric (thanks to Intel for code contribution) # The Myrinet MX network module, which had a life cyle from 1.1 till 3.1.2, has now been deleted. # Several other minor bug fixes, memory leak fixes, and code cleanup.

Re: [mpich-discuss] Possible integer overflows at scale in gather.c
by Ignacio Laguna 02 Oct '15

02 Oct '15

Rob, I applied the patch and the analysis doesn't report any scale-dependent overflow now. Thanks! This fixes it. If you are interested, I could try the analysis on other parts of mpich that perhaps are not frequently used -- I only tested these functions: broadcast, scatter, gather, reduce, alltoall, gatherv, isend, irecv, and wait. I didn't try I/O functions for example. We could coordinate this in this forum or in a separate email. Just let me know. Unfortunately, until we release it, it can only be tested on my side. Thanks for your help!
