I'm using the UseParallel option in fminunc on a system with 64 cores (128 logical cores). What is the best way to set the number of parallel workers in the parallel pool? Is it best to set it to the number of physical (64) or logical (128) cores?

64, though you can try more. You might find a 10-20% improvement as you add more workers (most likely not 2x as you get to 128)
