Very nice! :^) This problem isn't exclusive to Python, however. Other multi-threaded applications can produce jumbled output like this, even when the threads (processes?) are running on independent CPU's. I use a very well-regarded application for molecular dynamics simulation: GROMACS, which I believe is written mostly in C (but there's even a little Fortran in it? And supposedly, this is critical to performance?). The GROMACS core program, mdrun, will grab as many CPUs as you allow it to use. The output of mdrun looks exactly like your little quip as each CPU reports back that it has started its piece of mdrun. -- http://mail.python.org/mailman/listinfo/python-list
