If you look around on Ebay, you can find old 16-core Opteron servers for
a few hundred dollars. It's not screaming performance, but 16 cores is
enough to get you started on scaling and parallelism in MPI. It's a
cheap cluster in a box.

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
