They compare against "GMP" and "GMP Optimised". Note that "GMP" here is some undefined precompiled variant, perhaps 32-bit and surely not the corrrect compile for their processor. "GMP Optimised" presumably is just a proper compile, not a variant improved by the authors. Here 2048-bit mod 64-bit runs quite similarly to their new code, although their diagram is not zero based making an apparent great difference. I am not sure one can draw any conclusions about the relative performance of the current GMP code and their suggested new method considering how they present the performance results. Niels and I have published improved algorithms for GMP's mpn_divrem_1 operation, but we have yet to finish implementing them. -- Torbjörn Please encrypt, key id 0xC8601622 _______________________________________________ gmp-devel mailing list gmp-devel@gmplib.org https://gmplib.org/mailman/listinfo/gmp-devel
