The individual programs aren't really parallelizable. (In CS jargon, they're conjectured to be P-complete, outside NC.) They're doing many sequential operations to a single piece of data. That's why I want to run them individually.

So instead I write a program to find the most efficient solution for each piece, calculate its likely runtime, solve an approximate bin-packing problem, and schedule each across a user-tunable number of processors.
