P-1 on OBD candidates - Page 4

Hi Ken, if necessary I can post my server specs again to get it qualification completed, or at least note that it is also an ECC system and all current P-1 assignments are using ECC RAM.

Qualifying as I laid it out involves being able to reproduce known factors, and to show run time scaling consistent with completion of good bounds OBD P-1 within 1-2 years solo. By now you have lots of iterations at OBD stage 1 to establish ~192M fft length iteration times. Some small ones (run to mersenne.ca lookup gpu72 row bounds) from https://www.mersenneforum.org/showpo...8&postcount=31 would be quick to run. Stage 2 would need ~64 GiB at OBD. ECC is one element of reliability but an errant CPU could make it miss a known factor.
