49.7 to 51.0 to 63-bit

James Heinrich · 2006-06-30, 12:40

I'll take 49.7-50.0 (currently done to 61-bit) and 50.0-51.0 (currently done to 62-bit) and bump them up to 63-bit. Rough ETA for entire range: end of August.

Hmm, this may take longer than first expected... it may be closer to November by the time I'm done this set (unless I can find more CPU power somewhere)

James Heinrich · 2006-07-24, 23:43

Update:
47.7-50.0 should be done ~Aug 02
50.0-51.0 should be done ~Aug 30
(TF now running in 64-bit mode under Vista... and it's waaaay faster than the 32-bit version)

47.0-50.0 completed to 63-bit. 7398 exponents checked, 223 factors.

I just "upgraded" from an Opteron165 to a Sempron2800+...
Actaully the Sempron and Opteron have identical TF performance at equal clock speeds; however because I'm down to a single core at a lower clock speed (1@2.0GHz vs 2@2.6GHz) this set now has an ETA of mid-November.

currently done 20737 exponents, 5403 remaining, 449 factors found so far

Have you emailed the results to George?

James,

It would seem that George did not get some of your work. There are about 5500 exponents in that range still listed at 62 bits. Could you try resending them?
