The weird thing is, a lot of his results have the *same* 64bit checksum value even though the message itself is different (diff # of curves or bounds). Some are the same message (same curves/bounds/checksum) which, again, isn't unusual for ECM since people can and do run the same # of curves and bounds on parallel threads. But then, how do we know he really ran 17 x 91 curves, or just did that one time and submitted 17 times? Also, the app ID indicated in the result says it came from: "Windows64 Prime95 v26" 250,000 curves with those bounds would have taken quite a bit of time, and for all I know he really did it: I have no opinion.

Does anyone know if and where I might find the mersenne.ca equivalent of http://www.mersenne.info/exponent_st...ine_graph/1/0/ ?

It seems odd that mersenne.ca contents list doesn't include such (not quite so) new facilities, such that a person can encounter them without learning a link from mersenneforum.org.

Hmm, seems this thread is about mersenne.ca but I wasn't subscribed to it so I didn't know there was stuff going on. Thanks snme2pm1 for bringing my attention to it.

Nice! Thanks!
BTW I think you should start to collect clLucas results in that table of cudaLucas fire power. By the same logic as the sistertable of mfaktX results contains both AMD and Nvidia boulders, now after msft's last additions, clLucas became quite competitive, at least (or "not only"?) for some ranges where power of 2 fft's are adequate (I would argue about "not only", thinking about the prices for new amd cards, but that is a different discussion). The idea is that the table of xxLucas could contain AMD results too. What do you think? Last fiddled with by LaurV on 20160212 at 02:27

It occurred to me that the prices in the tables have to be updated too. Especially for a K80, you could buy it now for $3800 (one used at $3900 and 13 new at $4100 on Amazon, just for example, the first popup when search by google). Therefore lowering the price from $5k on the table will really improve their "james' value ratio" (don't laugh, that is a very good indicator! ), making it highly comparable with the Titans, especially as we switch to higher and higher exponents, more memory (and especially ECC memory!) for larger FFTs becomes a must (and it should also count toward the score, but that is a different story). One can not anymore use the cheaper version of the gtx580 (the one with 1.5GB memory only) to run the higher FFTs required for a LMH exponent, at least 23GB is a must, therefore that will soon be only the niche of Titans and Teslas (or the elite versions of gtx 5/6/780 or 90 with 3GB of RAM) [edit, or other newer thingies yet to come, not forgetting AMD cards as clLucas got faster now] Last fiddled with by LaurV on 20160212 at 05:45
