by the new prst app. There are some issues with similar CPUs and Riesel Bases (-1), Sierpinski Base is fine:

GenuineIntel Intel(R) Celeron(R) J4125 CPU @ 2.00GHz [Family 6 Model 122 Stepping 8]
GenuineIntel Intel(R) Celeron(R) CPU N3150 @ 1.60GHz [Family 6 Model 76 Stepping 3]
GenuineIntel Intel(R) Pentium(R) Silver J5005 CPU @ 1.50GHz [Family 6 Model 122 Stepping 1]


The gwnum must have a bug, already reported to the dev.

If you have such errors with these CPUs, disable work for -1 bases until this is fixed.

With the server upgrade accomplished, we were able to convert SGS to fast double checking. This, by itself, essentially doubles the speed of SGS, and when combined with increased participation this has SGS on a pace to exhaust its sieve file (i.e., the nominal end of the project) before the planned shutdown date of December 15^th. The new plan is therefore to let SGS run to the end of the sieve file, regardless of when that occurs. The forum discussion thread about the SGS shutdown is here.

We're upgrading to new servers sometime within the next week. With minimal warning, all PrimeGrid servers will be down for several hours. Discord, of course, will remain available. Discussion and more information will be available on Discord as well as on the the forums. The forums will be offline during the upgrade, however, so Discord is where we can be reached during the upgrade.
