My experience with similar kinds of comparisons is that gnu fortran compilers are not very good, especially on 2-d problems. Try using a different fortran compiler to see if speeds improve. -Travis O. _______________________________________________ Numpy-discussion mailing list [email protected] http://projects.scipy.org/mailman/listinfo/numpy-discussion
