Hi

i have a few questions about speeding up processes.

1) do i have to parallelize my program to be able to accelerate it, or can i use it as is?

2) is it really faster? how much speed improvement are we talking about (for a reasonable price)

3) do i have to compile my program into an .exe using Matlab Compiler to be able to accelerate the program?

4) my program outputs jpg files. Where will they be outputed ? on my computer or elsewhere?

thanks

Jeff

I would advise contacting us on this one. The specialists who can help you here have more experience and resources to help. As for the specifics:

Yes, use parfor, spmd etc, to distribute work across the workers.
Your mileage will vary. If the computation is expensive and data transfer minimal, then you'll see a nice big speed up. If the computation is very fast but has to communicate large images back and forth, then probably not.
No. Your best bet is to follow (2).
I believe elsewhere, you'll have to retrieve them. If I get some time I could maybe test this for you.
