Best performance per dollar for CPU systems is usually one generation past mid core count single socket system, such as Intel Haswell or Broadwell Core i7. Might get lucky and find eg 12-core Xeon processors cheap now. If you want lots of MPI ranks per dollar, look at Intel Knights Corner Xeon

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. Damien On 5/20/2016 12:40 PM, MM wrote: Hello, Say I

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
