Strategic double and triple checks (PRP's, P1's, and special Certs too)
New sticky to house the lists. Post requests for DC and TC's and claim of exponents. The mods will keep the lists maintained in the top posts. Post with requests for rechecks and exponents claimed will be removed when the lists are updated.
Always register your claims right away. Those that are claimed but not registered will remain on the lists. If they are listed as being assigned to Anonymous (or others not known to be finishers) and show no progress, they will be moved to the watch list section. The lists are kept fairly up to date. The easy way to get some assignments (with Prime95):

Strategic LL Double Checks
Any exponent that has had a single First Time LL should no longer have an LL DC. It should get a PRP on a machine running Prime95 v30+ or GpuOWL v 6.11318+ that produces VDF (proof files). The extra effort to run the certification from the proof files vs the need for TC tips the balance in favour of the PRP (with the better error checking code.) Code:

Added the 2 extra arguments that can be in the assignment: ",3,1" 1,2,96365519,1: Number to test: 1 * 2^{96365519}  1 76: Trial factored to 2^{76} 0: Not sure about this one. (Maybe if P1 has been done or not? or how many PRP tests has already been done on the exponent?) [EWM comment: Per the assignmentformat examples on my Mlucas readme page, a 1 following the TF bit depth means this expo has had some p1 testing done but could use a deeper round of p1; thus a 0 presumably means no deeper p1 is warranted.] 3: PRP base 3. This is always 3 as standard for normal GIMPS candidates. 1: PRP type 1. This can vary between 15, but mostly 1 or 4 for older gpuowl tests. Prime95 and newer gpuowl versions and Mlucas? default to type 1 (and Prime95 uses type 5 for PRPCF tests on exponents with known factor(s)). Both PRP base and PRP type has to be the same for the PRPDC test as the original PRP test. PRP type from undoc.txt, the "(default is 5)" is only for PRPCF tests, the type number is 1 on normal PRP tests. Code:
PRP supports 5 types of residues for compatibility with other PRP programs. If a is the PRP base and N is the number being tested, then the residue types are: 1 = 64bit residue of a^(N1), a traditional Fermat PRP test used by most other programs 2 = 64bit residue of a^((N1)/2) 3 = 64bit residue of a^(N+1), only available if b=2 4 = 64bit residue of a^((N+1)/2), only available if b=2 5 = 64bit residue of a^(N*known_factors1), same as type 1 if there are no known factors To control which residue type is generated, use this setting in prime.txt: PRPResidueType=n (default is 5) The residue type can also be set for PRP tests in worktodo.txt entries making this option somewhat obsolete. And also for base >3, some versions of gpuowl, PRP res type 0. Gpuowl supported PRP res type was 1 for some versions, 4 for others, 1 currently. Worktodo formats for all common applications are described in https://www.mersenneforum.org/showpo...8&postcount=22 Last fiddled with by ewmayer on 20200712 at 23:37 Reason: Added clarification re. the "more p1 needed?" field in PRPDC assignments

DC's on suspect single LL's should no longer be done.
Any single suspect LL should be redone with v30 as PRPVDF. The balance between the DC and higher than usual TC rate vs running a fresh a PRP & cert lean toward the PRP path to require fewer cycles long term. The error checking is better on PRP. TCLLs still make sense to clean up as LL (the required quad rate is low enough).

A large exponent, normal proof power. I've changed the server to treat CERTS that require more than the equivalent of 1 million squarings of a 200 million bit number in this special way.

Two weeks ago, when the test was at 95%, there was no electrical power for a minute during a storm. After restarting the test, there was a warning that at least 15 Gerbicz errors occurred and also ROUNDOFF > 0.4. The test went into a seemingly endless loop while reading from BU2. I stopped the test, exited from the app, and installed the latest (at that time) prime95 version 30.7b4 (the previous one was 30.3b6). The test then tried to read from BU3 and after some time continued and finally reached 100%. The server shows error code 00F00100 for this test.
