A new AMD mpn_mod_1_2 used to run at 4.0c/l now runs at 3.5c/l which is optimal. Brian , for the windows conversions note that for all the different cpus , mod_1_1's and mod_1_2 etc are all minor re-arrangements of each other. I've adapted my search program to accept prologue and epilogue code to the loops, this helped find the code above , hopefully it will help the Intel chips as well as they suffer much more from this problem.
