I guess you're talking about shootout.alioth.debian.org tests? > Beating Intel Fortran with a dynamic scripting > language... How is that even possible? It's possible that in the cases where Lua wins, the Lua code is not completely equivalent to the Fortran code, or uses stuff such as strings for which Lua's default implementation may be efficient. At least in the mandelbrot example some things differ. I wonder if Lua there takes advantage of SIMD instructions because the author of the code has manually changed the inmost loop to process two elements at once? -- Pauli Virtanen _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
