Also, within the compute clusters, you have essentially 3 different types
- massively parallel clusters, shared-memory clusters, and pipeline
clusters, each of which are better for different workloads.

Massively parallel clusters - The computation is easily dividable among
any number of nodes, and very little data is needed to be shared among
nodes.

Pipeline clusters - There are X independent jobs, so you can split up the
process by at most X nodes.

Shared memory clusters - same as either above, but a lot of memory sharing
needs to take place.  This usually requires specialized equipment.
