Re: [OMPI users] Stream interactions in CUDA

Hi Justin from looking at your code it seems you are receiving more bytes from the processors then you send (I assume MAX_RECV_SIZE_PER_PE > send_sizes[p]). I don't think this is valid. Your transfers should have matched sizes on the sending and receiving side. To achieve this, either

Re: [OMPI users] Stream interactions in CUDA

Hi Justin, Quick grepping reveals several cuMemcpy calls in OpenMPI. Some of them are even synchronous, meaning stream0. I think the best way of exploring this sort of behavior is to execute OpenMPI runtime (thanks to its open-source nature!) under debugger. Rebuild OpenMPI with -g -O0, add some

[OMPI users] Open MPI videos

Hi all For those of you who are interested in how Open MPI works, Greenplum/EMC recorded a set of talks last week covering several relevant topics. These talks are intended to help new developers become familiar with the more common parts of the code base. Greenplum is happy to make these

Can you send the config.log for the platform where it failed? I'd like to see the specific compiler error that occurred. On Dec 12, 2012, at 10:33 AM, Siegmar Gross wrote: > Hi, > > I tried to build openmpi-1.6.4a1r27643 on several platforms > (Solaris Sparc, Solaris x86_64, and Linux x86_64)

thank you for your reply and I apologize for my English and for my mistake, in every way I have had configured OPMI with this /usr/local/ prefix. 2012/12/12 > Send users mailing list submissions to > us...@open-mpi.org > > To subscribe or unsubscribe via

ompi-migrate is not in the 1.6 release. It is only available in the Open MPI trunk. On Tue, Dec 11, 2012 at 8:04 PM, Ifeanyi wrote: > Hi Josh, > > I can checkpoint but cannot migrate. > > when I type ~openmpi-1.6# ompi-migrate ... I got this problem > bash:

[OMPI users] problem configuring openmpi-1.6.4a1r27643 on Linux

Hi, I tried to build openmpi-1.6.4a1r27643 on several platforms (Solaris Sparc, Solaris x86_64, and Linux x86_64) with Solaris Studio C (Sun C 5.12) in 32 and 64 bit mode. "configure" broke on Linux (openSuSE Linux 12.1) for the 32 bit version with the following error: ... checking if Fortran 77

Re: [OMPI users] openmpi-1.7rc5 cannot install when build with ./configure --with-ft=cr

The checkpoint/restart code in the 1.7 branch is almost certainly broken as the developer/maintainer of that code graduated and left for a colder climate. We do not yet have someone to take their place, so the future of that capability is somewhat in doubt. Afraid you'll have to stick with the

Well, this > LD_LIBRARY_PATH = /usr/local/bin certainly isn't right - it needs to be /usr/local/lib, based on the output below. What prefix did you provide to configure OMPI? On Dec 12, 2012, at 4:11 AM, Extreme Programming wrote: > Hi, I have just installed openmpi 1.7

Re: [OMPI users] OpenMPI-1.6.3 MinGW64 buildup on Windows 7

I know 1.6.3 is broken for Win builds with VS2012 and Intel. I'm not a MinGW expert by any means, I've hardly ever used it. I'll try and look at this on the weekend. If you can post on Friday to job my memory that would help. :-) Damien On 12/12/2012 3:31 AM, Ilias Miroslav wrote: Ad:
