Yes, that runs (almost) all parts of the code in parallel.

We (currently) support only a single GPU for LB: If you do mpirun -np 8 ./Espresso file.tcl, the code will execute with 8 cpu's that communicate over MPI and a single GPU, that is installed in the node of thread index 0. Multiple GPUs require quite dramatic changes, and thus is not really planned for the close future.
