Hello,
Say I don't have access to a actual cluster, yet I'm considering cloud
compute solutions for my MPI program ultimately, but such a cost may be
highly prohibitive at the moment.
In terms of middle ground, if I am interesting in compute only, no
storage, what are possible hardware solutions out there to deploy my MPI
program?
By no storage, I mean that my control linux box running the frontend of
the program, but is also part of the mpi communicator always gathers all
results and stores them locally.
At the moment, I have a second box over ethernet.
I am looking at something like Intel Compute Stick (is it possible at
all to buy a few, is linux running on them, the arch seems to be the
same x86-64, is there a possible setup with tcp for those and have
openmpi over tcp)?
Is it more cost-effective to look at extra regular linux commodity boxes?
If a no hard drive box is possible, can the executables of my MPI
program sendable over the wire before running them?
If we exclude GPU or other nonMPI solutions, and cost being a primary
factor, what is progression path from 2boxes to a cloud based solution
(amazon and the like...)

MM

1. You can run MPI programs in a single computer (multi-core
multi-processor). So, in principle, you don't need a cluster, not even
two machines. If you want a proof of concept across Ethernet, two old
desktops/laptops connected back to back (or through a cheap SOHO switch)
will do.
2. Not trying to dismiss your question, although its scope goes beyond
MPI (and OpenMPI), and is more about HPC and clusters.
However, if you ask this question in the Beowulf mailing list,
you will get lots, tons, of advice, as the focus there is precisely
on HPC and clusters (of all sizes and for all budgets).
