Tim, thanks for trying this out ...
Now you should be able to let part of the same OpenMPI application run on
the host multi-core side and the other part on the MIC. IntelMPI can do
this using an MPMD command line where the Xeon binaries run on the host,
whereas the MIC ones on MIC card(s).

Hi Tim
Quick question: can the procs on the MIC communicate with procs on (a) the
local host, (b) other hosts, and (c) MICs on other hosts?
The last two would depend on having direct
Hi Tim

The last two would depend on having direct access to one or more network
transports.

Hi Tim,
Well, in general and not on MIC I usually build the MPI stacks using the Intel
compiler set. Have you ran into s/w that requires GCC instead of Intel
compilers (beside Nvidia Cuda)? Did you try to use Intel compiler to produce
MIC native code (the OpenMPI stack for that matter)?

Out of the box, there is no gcc on the Phi card. You can use the cross
compiler on the host, but you don't get gcc on the Phi by default.

Thanks Tom, that sounds good. I will give it a try as soon as our Phi host here

I assume that all the prerequisite libs and bins on the Phi side are available
when we download the Phi s/w stack from Intel's site, right ?

Do you guys have any plan to support Intel Phi in the future? That is, running
MPI code on the Phi cards or across the multicore and Phi, as Intel MPI does?

Hi Michael,
Because a Xeon Phi card acts a lot like a Linux host with an x86 architecture,
you can build your own Open MPI libraries t

Rolf will have to answer the question on level of support. The CUDA code is not
in the 1.6 series as it was developed after that series went "stable". It is in
the 1.7 series, although the level of support will likely be incrementally
increasing as that "feature" series continues to evolve.

Hello OpenMPI,
I am wondering what level of support is there for CUDA and GPUdirect on
OpenMPI 1.6.5 and 1.7.2.
I saw the ./configure --with-cuda=CUDA_DIR option in the FAQ. However, it
seems that with configure v1.6.5 it was ignored.
Can you identify GPU memory and send messages from it directl
