Parallel Computing Toolbox Matlab

Hi everybody,

i have many matlab files and i wonder if i can use Parallel Computing Toolbox to execute them at the same time ? Is it possible ? How can i do this ?

Many thanks :)

That is going to depend on what they do. Sometimes it would work. For example, you could construct a cell array of function handles, open a pool, use the facility to add the source files to the pool, then enter an spmd block. The spmd bock content would look like

feval(HandlesCell{labindex})

Provided that your pool size was as large as the number of functions to execute.

You might also want to try parfeval for this use.

Thanks, but i'm a beginner in this subject... basically i have three files a.m, b.m and c.m. Is it possible to execute them at the same time ?

It depends on what they do.

parpool(3)
spmd
  switch labindex 
    case 1: a() ;
    case 2: b() ;
    case 3: c() ;
   end 
  end
