Hi all

 

I am about to purchase a laptop and I intend to use it in program development (initially FORTRAN and C++). I will also be creating my own programs with MPI (parallel processing). I wondered if anyone knows if the all compute cores in some APUs can be used in parallel processing. For example, if I had the A10-7300 can I use all 10 compute cores in my program? In other words, can this terminal command  be used

 

     mpiexec -n 10 my_mpi_prog

 

Thanks for your help!
