3) Message boards : Number crunching : Wrong date and task for found prime (DC), prime found twice (Message 124035)

On 27th of December I got a prime in the SGS project as Doublechecker:



In my list of found primes I got the folowing:



The "task" links to:



So, the prime is found twice? Same task sent two times? Strange!

Any Ideas?

Hi Ian,

thanks for the new builds. I'm testing on windows using PRPNET.

AFAIS everything works as expected. The checkpoint file issue is gone!

8) Message boards : Number crunching : fpga's the new way? (Message 60255)
Posted 3335 days ago by Rainer EmrichProject donor
No, you're wrong. These are ASICs.

http://www.butterflylabs.com/products/

And as stated in the forum:
https://forums.butterflylabs.com/showwiki.php?title=FAQ:Hardware+Questions

Can your products be used for things like BOINC, SHA1 or some other type of computing?

Our FPGA products may be able to be reprogrammed for other computing uses, although we do not currently have any bitstreams for other projects, other than bitcoin.
Our ASIC devices are designed to only do a double SHA256 calculation, and therefore can not be used for anything else.
