Hey all. Im trying to sort out how to get MATLAB running as best as possible. I have a pretty decent new machine.
12GB RAM Core i7 3.2Ghz Cpu and lots of free space. and a strong graphics card.
However when I run the benchmark test of MATLAB (command bench) it lists the computer as being near the worst, around a Windows XP single core 1.7Ghz machine.
Any ideas why and how I can improve this??
Thanks very much
Firstly, I would recommend re-running the bench command a few times to make sure MATLAB has fully loaded all the libraries etc. it needs. Much of MATLAB is loaded on demand, so it's always best to time the second or third run.
MATLAB automatically takes advantage of multiple cores when executing certain operations which are multithreaded. For example lots of elementwise operations such as +, .* and so on as well as BLAS-backed operations (and probably others). This page lists those things which are multithreaded.
Parallel Computing Toolbox is useful when MATLAB's intrinsic multithreading can't help (if it can, then it's usually the fastest way to do things). This gives you explicit parallelism via PARFOR, SPMD and distributed arrays.
