Parallel FX and the number of cores

[Jon Harrop]

I'd like to measure performance results as a function of the number of cores
by restricting parallel FX to using only a subset of my cores. Is this
possible and, if so, how?

Certainly with PLINQ - the call to AsParallel optionally takes the
number of threads to use.

For things like Parallel.For you can specify a TaskManager and
TaskCreationOpt ions to use. I don't have time to look them up now, but
I strongly suspect they will have options for how many threads to use.
