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, other than that neither are supported. If forced to choose
between OpenMPI and the OS/toolchain, I am likely to choose the
OS/toolchain and pursue other avenues for parallelization. That's part
of what I am trying to determine with my inquiry.
To summarize some of the question areas:
1) The OS I am working with does not support MP
2) nor does it support pthreads
3) the hardware is quad-core SoC with an integrated memory controller
4) I'd like to see if it possible to utilize hwloc and shmem to build an
asymmetric multi-processing system where only one core has I/O but the
other three can run the executable
This is a fairly dedicated system to be used for analyzing ODEs (disease
models). The hardware is cheap ($200) and uses very little power (can
run off a 12v battery), and the toolchain and OS are all BSD-licensed
(and everything will be published under that license).
If someone is available for off-line discussion (to minimize unnecessary
traffic to the list), I'd be more than willing to summarize the
conversation and contribute it to the online documentation.
Thank you,
tim
