Re: [OMPI devel] "The MPI_Init() function was called before MPI_INIT was invoked."

Thanks for the bug report. We should probably cleanup the reporting of this type of error. I think someone was looking into the "*** The MPI_Init() function was called before MPI_INIT was invoked." issue since it came up in a different bug report. But I'll file a ticket on this so when we get back

Re: [OMPI devel] Using BLCR tools to checkpoint Open MPI applications

Eric, Thanks for the great work on this integration. I filed a ticket for the problem areas that you highlighted with the Open MPI side of the integration so we do not lose track of them. https://svn.open-mpi.org/trac/ompi/ticket/2842 Hopefully we will get some cycles to address these issues i

Re: [OMPI devel] RFC: CUDA register sm and openib host memory

Rolf, Can we have some more details on how this will improve performance of sending GPU device memory? I fail to see how registering the backend shared memory file with CUDA is supposed to do anything at all, as this memory is internal to Open MPI and not supposed to be visible at any other lev

Re: [OMPI devel] RFC: CUDA register sm and openib host memory

Hi George: In the current implementation, to send CUDA device memory, we move it through internal host buffers. In other words, we force the usage of the send protocols. If the host buffers are CUDA registered, then when we call cuMemcpy to move the data into those host buffers, the cuMemcpy p

[OMPI devel] [patch] add explicit IT instructions in ARM assembly

In the Linaro 11.05 Linux metadistribution, and hence most likely in Ubuntu 11.04, the GNU assembler no longer defaults to -mimplicit-it=thumb, causing the build to fail when compiling on this platform. The attached trivial patch adds explicit IT instructions where required, permitting a succ
