Since Python has been mentioned in this context: Could not Python's threading model and implementation serve as a guideline?
>From a few simple benchmarks I've run, it seems as if the Python interpreter itself is thread-safe but not threadable. That is, when I run something "pure Python" like a recursive function that returns the nth Fibonacci number in parallel, there is no speed-up for 2 threads on a dual-processor machine. However, calling sleep in parallel does scale down with the number of threads, even on a single-processor ;) Real-life code does tend to speed up somewhat, though never as much as one would hope. Just an idea... René ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
