however maybe not all people on gmp-devel are interested by the detail of all patches and the corresponding discussions? Personnally I subscribed to gmp-devel to be informed about new ideas or new algorithms being implemented in GMP. I expected a low rate of about one message per day, which was the case in 2012. So far in March we have over 100 messages in less than 6 days! I'm sorry I cannot follow so many messages thus if this continues I will have to unsubscribe. Finally to increase the technical content on this list Alexander Kruppa told me about the following preprint of Ernst Mayer: arxiv.org/abs/1303.0328. On a Core 2, he claims a mpn_mod_1 running at 6 cycles per limb, and a mpn_divrem_1 at 12.5 cycles per limb. On my computer GMP 5.1.1 runs at about 12 and 24 cycles per limb respectively: tarte% ./speed -s 1000,2000,5000,10000 -c mpn_mod_1.16031552068505892269 mpn_divrem_1.16031552068505892269 overhead 6.13 cycles, precision 10000 units of 5.00e-10 secs, CPU freq 2000.00 MHz mpn_mod_1.16031552068505892269 mpn_divrem_1.16031552068505892269 1000 #12682.00 24064.00 2000 #25024.00 48187.00 5000 #62084.00 119298.00 10000 #123786.00 238280.00 tarte% cat /proc/cpuinfo | grep "model name" | head -1 model name : Intel(R) Core(TM)2 Quad CPU Q9550 @ 2.83GHz Paul _______________________________________________ gmp-devel mailing list gmp-devel@gmplib.org http://gmplib.org/mailman/listinfo/gmp-devel
