Only manual via admin.
The admin distributed the tasks.
17000 digits are alluring. 2nd place in the TOP-20 page.

Justin (enderak) has recently run a double check on the sequence for 2^1191375+8543, verifying that it is the smallest prp of its sequence. I have just finished checking that all the residues match the residues I found with pfgw a couple of years ago. It took me awhile to find the residues from the range 1.00-1.05M, or I would have posted this a few days ago! Some of the residues were matched to 62-bit residues from an older version of pfgw.

I also have a similar double check running on the sequence 2⁹⁸³⁶²⁰+60451 on a slow computer. After this one, only the five sequences of Five or Bust will remain to be double checked.

Awesome, down to 20 probable primes left, and one undiscovered prp! I don't know what we'll do for excitement around here once Engracio finishes his Primo run. Hopefully, we'll find that last prp soon, as this is the longest period we have gone without a new prp discovery.

Thanks, Norman, for a significant contribution to a nice sub-project, as well as an important extension of Primo's capabilities.

Thank you Norman. I am now running Phase 2 on the first 500 test and did what you instructed and sf= and pm= are not there anymore.

w00t

The test runs are finally picking now. Hope to be done soon.

I would like to thank Norman for all his help and finding out where I messed up on my prime hunting. Without him I feel I would have wasted months of continues work. Thank you again Norman.

I have certified 2^31544+19081 as a prime and in the process of checking and signing the certificate by Primo. The process will probably take all weekend. Unless I ran into problem and not followed/verified Norman's process.

Here is hoping I can post again with success.
