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 P1 assignments are using ECC RAM.

Current TF & P1 status is shown at https://www.mersenne.ca/obd. Current indicated Level is 24.05.
3321928171 TF completed to 92 bits, 20220205 by mersenne.ca user johnny_jack, reserved for P1, stage 2 5% complete 3321928307 TF completed to 92 bits, 20220223 by kriesel; reserved for P1, stage 2 ~14% complete on an ECC ram system 3321928319 TF completed to 92 bits, 20220226 by kriesel; reserved for P1, stage 2 ~16% complete on an ECC ram system 3321928373 TF completed to 92 bits, 20230223 by kriesel; right to reserve P1 by kriesel extends to 20230323, and has NOT been ceded. (reserved anyway on the https://www.mersenne.ca/obd page by Rafael R for P1 ~20230302) 29 other exponents have been completed to 90 bits, and are available for reservation to a higher TF level. These are in the exponent range up to 3321929987, as part of an effort to go to ~30 exponents eventually remaining with no known factors after TF and P1 factoring completion to recommended levels and bounds, for eventual PRP/GEC/proof & CERT when hardware and software development advance sufficiently. Anyone with a sufficiently fast GPU, or fast CPU with at least 64 GiB ram, is welcome to help with TF or P1 respectively. (But please follow the rules!) At the moment: OBD TF completed to 92 bits, reserved for P1 and in progress in P1 stage 2: 3 OBD TF completed to 92 bits, by Kriesel 20230223, so restricted for reservation to kriesel until 20230323: 1 OBD TF completed to 92 bits, ready for reservation by anyone with qualified hardware for P1: 0 OBD TF completed to 91 bits: 0 OBD TF completed to 90 bits, reserved to 91 bits: 0 Systems with qualification(s) completed & posted for OBD P1: 3 (1 is unconditionally) Exponents completed thru stage 1 P1: 3 Exponents completed thru stage 2 P1: 0 kriesel is the only user that has yet posted system qualification results. (This status summary is specific to OBD Mersennes. See also Ernst Mayer's F33 P1 effort, mentioned in the Xeon Phi hardware thread.) Last fiddled with by kriesel on 20230302 at 19:44

OBD P1 coordination proposal revised
OBD P1 is now feasible. For now, Mlucas v20.x is the only known software capable of OBD Mersenne P1 factoring, with sufficiently large fft lengths and several months of QA testing and revision (patching) accomplished. The latest version is recommended, which is V20.1.1 patch 20220706. See http://www.mersenneforum.org/mayer/README.html and https://mersenneforum.org/showthread.php?t=27295
I propose the following:

Since the mersenne.ca pages have been changed, this is now called the target row.
Quote:
A proper P1 on it requires ~21663. GHD, which would have been comparable effort to 3/4 of the total mersenne.org P1 GHD credits for him in the preceding year. (Which I think were produced mostly by the more efficient new stage 2 code of mprime, while OBD P1 requires Mlucas for sufficiently large fft length.) OBD work produces no GHD credits on mersenne.org, whether performing TF or P1. Exponent status update attached below. Last fiddled with by kriesel on 20230305 at 18:00
