The above example requests two whole nodes for a total of 64 processes. This is certainly more processors than is needed for the silicon tutorial case. Please be aware that suitable selection of a process count is complicated, but it is your responsibility to choose an efficient number | The above example requests two whole nodes for a total of 64 single-threaded processes.
