Hi, I have a desktop machine with 4 cores available. 1) I wonder whether, calling a pool of 4 workers with the PCT, there will be 4 workers working in parallel, or just 3 since 1 is the client. 2) Working with a cluster workstation (with MDCS), when I connect to the master node (client), I run my code in parallel calling "n" workers, and I want to compare the simulation time of the parallel computation with that of the sequential one (I want to see the speedup). For the sequential computation, should I call in the master node matlabpool open 1 (calling 1 slave node from the master node) or should I work directly with the master node, than I don't need to call a matlabpool? Thank you in advance.
