Optimize Matlab code for multicore

jzamoras · May 12th, 2008, 3:10 pm

Hi All, I just bought a quad core computer (Q6600 Intel Quad) and I noticed that it's just twice fast as my 2 GHz centrino. I suppose that something can be done to achieve better performance. Is there a tutorial about this issue?Best,Jaime

Jaime,This one is old dated (an year ago) but seems to explain your issue: I have a PC that runs on a multi-core processor, and I would like one session of MATLAB to take advantage of the multiple processors. Regards,Piter Dias

From what I've read, Maybe you could try JOCaml etc, havent used it myself very much though.But there is a school of thought that functional languages could make parallel programming easier.

Jamie,MatLab R2008a (R2007a i believe as well) is already optimized for multi-core. If you need to make sure goto;file (toolbar) preferences General Multi threading a button and check box will enable/disable and will give you the option to select the amount of threads (I have 8 but I still choose automatic)let me know if this is the answer you were looking for.
