Yes, I was going to aggregate some of the conversations that I have had
(four of them, thank you much for the responses). The consensus was
that neither hwloc nor OpenMPI were appropriate for my project.
The use of shared memory was proposed by Jeff Squyres and one other
person. From there is
To follow up for the web thread: I talked with Tim about this off-list.
Not only will Open MPI likely not work in Tim's environment, MPI itself is
probably too much for what he's trying to do.

My apologies for the duplicate posts. This was originally sent from my
university email account. However, there was a configuration error at
the mailing list host site that prevented email exchange between the
host and my university, including confirmation that I had subscribed.

I don’t see how Open MPI can operate without pthreads

Hello Everyone,
I'm inquiring to find someone that can answer some multi-part questions
about hwloc, OpenMPI and an alternative OS and toolchain. I have a
project as part of my PhD work, and it's not a simple, one-part
question. For brevity, I am omitting details about the OS and
toolchain, othe

Hi Brice,
Thank you for your response. Yes, possibly hardwiring everything would
be easier. I was thinking I could use OpenMPI for the signaling between
the cores on an OS that doesn't support multi-processing, using the
shmem approach. The executable is the same for each CPU image, but the
Hello
I am available for off-line discussion for the hwloc side of things. But
things look complicated here from your summary below. I guess there's no
need for binding on such a system. And topology is quite simple, so it
might be easier to hardwire everything.
