Parallel algorithms can offer improvement. Your 16 cores might amount to a 10x speed up if used well for this kind of thing. The double-threading probably can't be exploited in CPython. However I think that many of the things that SymPy is slow for have *really* bad asymptotic performance: think O(N!) rather than O(N^2). Many orders of magnitude improvements can be made by spotting these where more efficient methods are possible. It's not hard in a CAS to accidentally generate enormous expressions and end up simplifying them down again. This leads to many situations where it would be vastly more efficient to somehow take a more direct route. -- You received this message because you are subscribed to the Google Groups "sympy" group.
