Please fix the hcoll test (and code) to be correct.
Any configure test that adds /usr/lib and/or /usr/include to any compile
flags is broken.
And if hcoll include files are under $HCOLL_HOME/include/hcoll (and
hcoll/api) then the include directives in the source should be
#include
and

i do not know the context, so i should not jump to any conclusion ...
if xxx.h is in $HCOLL_HOME/include/hcoll in hcoll version Y, but in
$HCOLL_HOME/include/hcoll/api in hcoll version Z, then the relative path
to $HCOLL_HOME/include cannot be hard coded.
anyway, let's assume it is ok to hard

comments to it
Hi!
In my current application, MPI_Send/MPI_Recv hangs when using buffers in
GPU device memory of a Nvidia GPU. I realized this is due to the fact
that OpenMPI uses the synchronous cuMempcy rather than the asynchornous
cuMemcpyAsync (see stacktrace at the bottom). However, in my
application,

Because only the devel package includes the necessary pieces to set memory
affinity.

I think Dave's point is that numactl-devel (and numactl) is only needed for
*building* Open MPI. Users only need numactl to *run* Open MPI.
Specifically, numactl-devel contains the .h files we need to compile OMPI
against libnumactl:
$ rpm -ql numactl-devel
/usr/include/numa.h
/usr/include/num
Dear Users,
I have run into a problem with openmpi-1.8.7. It configures and
installs properly but when I tested it using examples it gave me numerous
errors with mpicc as shown in the output below. Have I made an error in the
process?
Amoss-MacBook-Pro:openmpi-1.8.7 amosleff$ cd examp
I talked with Jeremia off list and we figured out what was going on. There is
the ability to use the cuMemcpyAsync/cuStreamSynchronize rather than the
cuMemcpy but it was never made the default for Open MPI 1.8 series. So, to get
that behavior you need the following:
--mca mpi_common_cuda_cum
I have cloned Gilles' topic/hcoll_config branch and, after running
autogen.pl, have found that './configure --with-hcoll' does indeed work
now. I used Gilles' branch as I wasn't sure how best to get the pull
request changes in to my own clone of master. It looks like the proper
checks are happe
I can successfully run my OpenMPI 1.8.7 jobs outside of Son-of-Gridengine but
not via qrsh. We're
using CentOS 6.3 and a heterogeneous cluster of hyperthreaded and
non-hyperthreaded blades
and x3550 chassis. OpenMPI 1.8.7 has been built w/the debug switch as well.
Here's my latest errors:
