Nested parallel evaluations (seeNo Nested parfor Loops). Only the outermostparforloop runs in parallel, the others run serially.

Reproducible results when using random numbers (seeReproducibility in Parallel Statistical Computations). How can you get exactly the same results when repeatedly running a parallel computation that uses random numbers?

worker— An independent MATLAB^®session that runs code distributed by theclient.

client— The MATLAB session with which you interact, and that distributes jobs to workers.

parfor— A Parallel Computing Toolbox™ function that distributes independent code segments to workers (seeWorking with parfor).

random stream— A pseudorandom number generator, and the sequence of values it generates. MATLAB implements random streams with theRandStreamclass.

reproducible computation— A computation that can be exactly replicated, even in the presence of random numbers (seeReproducibility in Parallel Statistical Computations).
