I took these as LL-DC. Given that there are already two [non-matching] LL results, the probability that I also mismatch is likely less than the PRP-VDF overhead, right? I suppose it probably makes sense to continue the Triple Check list as LL.

PS: Thank you for splitting off the PRP-VDF and DC thread, although it seems to have devolved into a thread about patches. Anyway, it is a very exciting development!

I concur doctor.

 2020-07-25, 03:29 #598 Runtime Error   Sep 2017 USA 12810 Posts @UNCwilly Hey, I just realized this one 87829211 is a PRP TC instead of LL. I restarted my worker as PRP-VDF, only 10M iterations wasted. Is there an easy way to query the list for those that are PRP and not LL, in case there are more? Thanks in advance.

Shouldn't different PRP residue types produce different residues?

 2020-07-31, 20:13 #602 kruoli     "Oliver" Sep 2017 Porta Westfalica, DE 23×31 Posts Some residue types will result in the same residue when there is no factor. But in general, you are correct. But nonetheless, we need a matching DC as long as we do not have a VDF on a run.

I am not sure. The worktodo lines (and I fixed the missing ",") I made followed ATH's info. Each of the exponents have a base 3, type 1 test.
The exponents were part of ATH's list that was posted in the TC list. I went through the list to remove them from the LL's.

As far as I understand the server is ready to receive the VDFs. I have been running PRP-CF's with VDFs and not seeing evil messages from the server.

Citation from undoc.txt of Prime95:
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.
Based on this, only the types 1 and 5 should yield the same results.
