C or C++ would work. He may want to check the assembly code that's generated too. > You might find "cython" helpful to easily combine Python parts > and "C" parts. In this case I doubt that involving Python will be helpful at all ... There won't be a lot for it to do: all the interesting stuff will happen at the level close to the hardware. There's tweaking the parameters for the benchmark, but that could be just command-line options. He may also want to instrument his programs using valgrind, time(1), oprofile and perf(1), and I guess the Python interpreter would introduce some noise there. /Jorgen -- // Jorgen Grahn <grahn@ Oo o. . . \X/ snipabacken.se> O o . -- https://mail.python.org/mailman/listinfo/python-list
