Strategic double and triple checks (PRP's and P-1's too)

Uncwilly · 2019-03-06, 21:10

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):

Grab the lines of the exponents that you will do.
Stop Prime95.
Edit your worktodo.txt, inserting the new lines, save it, and close the editor.
Restart Prime95
Go to the menu Advanced-> Manual Communication
Make sure "Contact PrimeNet server now" and "Send new expected completion dates to server" are checked. Hit OK
After Prime95 is done communicating, look and see if any of the new exponents don't have an Assignment ID (because they were already assigned.) If they don't, stop Prime95, reopen the worktodo.txt, remove those lines, save, then restart Prime95

Instructions for mprime:

Grab the lines of the exponents that you will do.
Stop mprime.
Edit your worktodo.txt, inserting the new lines, save it, and close the editor.
Delete the line starting with `LastEndDatesSent=` in `local.txt`.
Run `mprime -c` for force communication, and watch for errors: exponents that didn't get assignments should be removed from `worktodo.txt`.
Restart mprime.

~~This is the location for the DC list:~~

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 the newer version of owlGPU that produces VDF (aka Certs). The extra effort for the cert vs the need for TC tips the balance in favour of the PRP (with the better error checking code.

PRP=EDDC25414116177C4F046D79BE11A463,1,2,96365519,-1,76,0,3,1

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 2⁷⁶
0: Not sure about this one. (Maybe if P-1 has been done or not? or how many PRP tests has already been done on the exponent?) [EWM comment: Per the assignment-format examples on my Mlucas readme page, a 1 following the TF bit depth means this expo has had some p-1 testing done but could use a deeper round of p-1; thus a 0 presumably means no deeper p-1 is warranted.]
3: PRP base 3. This is always 3 as standard for normal GIMPS candidates.
1: PRP type 1. This can vary between 1-5, 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 PRP-CF 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 PRP-CF 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 = 64-bit residue of a^(N-1), a traditional Fermat PRP test used by most other programs
2 = 64-bit residue of a^((N-1)/2)
3 = 64-bit residue of a^(N+1), only available if b=2
4 = 64-bit residue of a^((N+1)/2), only available if b=2
5 = 64-bit residue of a^(N*known_factors-1), 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.

[edit]
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

DC's on suspect single LL's should no longer be done.

Any single suspect LL should be redone with v30 as PRP-VDF. 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.

TC-LLs still make sense to clean up as LL (the required quad rate is low enough).

There are at least 3,375 residues for exponents <45M spelling BAD correctly:

Yes, I know. That was supposed to be a joke.
