WorkPreference Help

[LOBES]

Hello, I am trying to find the WorkPreference setting to put into my prime.txt so that I only get "PRP cofactor test double-check", or PRP-CF-D.

I thought it was 151, but ended up getting "PRP double-check" which would take way too long.

You know what would be a wonderful addition to one of the Help pages? If the following page:

https://www.mersenne.org/worktypes/

Had one extra column on it that would tell you the WorkPreference number corresponding to that type of work.

Thanks in advance!

Thanks in advance!

https://www.mersenneforum.org/showthread.php?t=23992 has a quoted section from a prime95 source code file, with all except CERT worktype that was very recently introduced. As I recall that's 200.

Thank you ... looks like I'm wanting 161.

I still think that would be a great addition to the Work Types info page.

You're welcome, and agreed. The Primenet API documentation could use an update too.
The problem is, there's only one George Woltman in GIMPS.
PRP proof and certificate verification was correctly given priority over almost everything else.
