Which is a quite short test. :P

But i agree, we should sort and look out if there are proven prp´s with an certificate; before testing them.

I also think its needed to import the TOP PRP page´s prps into FactorDB. This would add some decent amount of prps <20000 dd; plus "many" on "U" numbers.
Which brings me back to searching for prp´s in the u list; via allowing to upload PFGW´s results. (only for loged in users). I dont think there many PRP´s, but maybe a few hundrets if we are lucky enough.

Just my two cents in here.

I might be able to get back into PRP related stuff soon. Would go up to 15K dd alone, and open for cooperations for larger numbers. ^-^

7220 digits is not much. I don't have my notes right now, but I believe I can do that in less than a day.

There are several dozen 6K-8K dd numbers that are prp cofactors of M(n) -- including composite n mostly -- that I work on myself without much ado. Maybe I'll finally make a post about it one day. Although, paused right now for the summer. The weather is just too hot.

I have one linux server running, temps are not a problem. ^^

Hit me up if you need some help, the server is curriently busy with other stuff which can be safely paused for a while. ^^

Well, if you complete this (probable) prime, you can run (91^4421-1)/90 (8659 digits) and 60^4663-59^4663 (8292 digits).

This number is still "PRP" in factordb, did you run it?

What I'd like to do is have Primo running all the time, but have it take a back seat when CADO-NFS is running. Would it be better to give the CADO-NFS a high priority and Primo a normal priority, or to give CADO-NFS a normal priority and Primo a low one?

It seems the former would be better, because Primo would have a lower priority than all the other processes that are running, but I'm not sure what I would need to do to raise the CADO-NFS priority. Does the priority of child processes retain the nice level of the parent?

On my 48 core Primo does not always use all cores, especially at times in phase 1. I sometimes run lower priority jobs to soak up spare cycles.

Setting the priority of Primo will filter down to child processes as they spawn.

Thanks! I was thinking more about raising the priority of CADO-NFS, but now I'm on an even different path. I think I'll send an Abort signal to Primo, eventually followed by signals to load the .tmp file and continue. I'm manually doing this now - I think I can automate it.

I do still need to study "nice" a bit further still. . .

Looks like we'll eventually be able to run Primo in Windows again, starting sometime next year: https://devblogs.microsoft.com/comma...-with-windows/

Hopefully it'll work. I'm tired of loading up a Linux VM every time I want to do an ECPP test.

There is already a way to run Primo on the Linux sub-system in Windows. We have instructions somewhere on MersenneForum but I can not find them.

Found it! https://www.mersenneforum.org/showpo...&postcount=439

Thanks.

P.S.: Any chance you could tell me what the password is to download the newest Xming release? I don't want to use the 2007 version.
