Getting others to do the work on exponents I like (was: Trial Factoring Progress)

There were no sensitive information written inside that email, only about the PRP tests and some M168M exponents which was what this thread has been about. I thought it'd be improper to share if the emails contained any personal stories or feelings that were not related to the Mersenne Prime projects.

DrKirkby quit Gimps because he wanted other people to do the higher trial factoring on some of the front-wave exponents that he scheduled to run the PRPs on, then had some issues about Cat 0 and 1 assignments. He had a lot of cores and memories, so P-1 were easier for him. Since I just got a new PC with a fast GPU, I could bring most of the M107M+ exponents up to 2^79 within the matters of several hours each now.

I don't think anyone would care if I TF M105211111 up to 2^79 or 2^80, it's already a past history. If I had this new PC back half a year ago, the whole scenario would play out very differently. At least I could trade my GPU powers with DrKirkby's CPU powers, thus he wouldn't have that https://www.mersenneforum.org/showth...t=27037&page=3

TF M168M exponents from 2^80 to 2^81 will take me around 7 hours and 30 minutes which is about the same duration as 2^79 to 2^80 for M105211111.

I checked a few links, but without the helps of other forum members, I didn't know how to contact DrKirkby again or does he not want to be contacted again?

I don't know whether you can summon DrKirkby back to the forum and the Gimps project. I always believe there's a second chance for anything which have gone wrong the first time but not fatally failed.

If not, then I may have to get a Threadripper Zen 4 Workstation with 32 CPU cores and Radeon 7900 XT in year 2024(The earliest month when my father will allow me to buy another new PC with the only exception: I land on a new Mersenne Prime) to make up for that.

I have reserved them and allocated 12GB.
For your stability concerns, I'll use 30.7B9.

Let me know the total time to complete the P-1 of each exponent on your end. Those are tough and lengthy tasks, not very many users like to go after those.

The recommended bounds are listed on the following pages -

https://www.mersenne.ca/exponent/168692323

B1=1,050,000, B2=40,000,000 will take only slightly longer than B1=1,050,000, B2=39,000,000

I used to run P-1 with the smaller B2 bound than the GPU72 recommendation for 1 exponent, then Ben Delo had to redo the entire P-1 when he got assigned the PRP.

At the risk of arrest for criminal belaboring of the obvious, I formally ask you: Did you at least try sending him a PM to ask permission?

It is not that hard to find him elsewhere on the internet. That is the difference between an immature person and a mature person. The immature looks in one spot and say "this is impossible". The mature looks all around, says "This may be difficult and then continues on and finishes the task.

[edit]I just searched and had an email address for him in less than 30 seconds.

So what would it take for DrKirby to return to GIMPS? Why did he leave?

DrKirkby left because he was unable to reserve the Cat 0 and 1 assignments of the PRP tests, but that 120 days due limit have already past.

I sent him forum private messages many times without him responding back after he became inactive. I assumed it would notify his other emails that he had the new messages here. That was why I wondered whether he wanted not to be contacted again?
