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 communicat
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
Hello,
I'm working on an application using OpenMPI with CUDA and GPUDirect. I would
like to get the MPI transfers to overlap with computation on the CUDA device.
To do this I need to ensure that all memory transfers do not go to stream 0.
In this application I have one step that performs an
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 avail
Can you send the config.log for the platform where it failed?
I'd like to see the specific compiler error that occurred.

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.

ompi-migrate is not in the 1.6 release. It is only available in the Open
MPI trunk.

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
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?

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. :-)

Installation works fine, compilation too but when i executed the "mpirun -n

Thanks for your efforts, Damien;
however, in between I realized that this standalone Windows OpenMPI is built
from ifort.exe + cl.exe, and I have only MinGW suite in disposal...
For that reason I tried to build-up OpenMPI on Wi
