You need the Parallel Computing Toolbox. Once you have that, you can use any of:
  • spmd
  • parfor
  • parfeval
  • batch
Notes:
  • when you use parallel processes, only one at a time can access any particular GPU
  • Unless you specifically configure otherwise, the workers only get a single core to execute in. This can affect the results compared to the automatic parallel processing that MATLAB does for some operations. In particular, any kind of "reduction" such as sum() can come out slightly different for floating point numbers.
