Just to speak to this particular charge...

I sincerely don't ever mean to come across as arrogant, nor cause offense. I have been told this can be the preception to those who don't know me well.

I subscribe to the Scientific Method. I /presume/ everyone else does as well. The Method involves constantly challenging (and being challenged).

To share, I have been measured somewhat far on some of the ASRS vectors.

Everyone has his/her own personalities and the unique ways of using the words, thus unless you've met the person face to face, it's difficult to make a hardline judgement that another person is very arrogant.

Someone else can think drkirkby the same way if he/she hasn't been familiar with drkirkby long enough such as must run PRPs after TFs and P-1 finished by others. If I want something badly enough, I do everything myself. Of course, someone can think me the same way too because I do certain things other people don't agree with. Unless something is unlawful, it's probably not that big of a deal.

I don't refuse to do P-1 or trial factoring. But it is pointless doing trial-factoring on my CPUs, as GPUs are far more sensible for trial-factoring. I've done a little trial-factoring on my GPU, but it is not very good at trial factoring either, although its more suitable for trial factoring than PRP tests. My main workstation was more suited for PRP tests as it has a lot of cores, or P-1 as it has a lot of cores and RAM.

I've done P-1 tests multiple times - the subject of this thread should make that obvious.

When I was getting category 0 and 1 exponents, it was never necessary to do trial-factoring, and rarely necessary to do P-1 factoring either. However, contrary to what you stated in some other thread, category 0 and 1 exponents do not always have the P-1 done. Take a look for example at M104813497, which Ben Delo is doing a PRP test on. Ben did the P-1 too, using B1=890000, B2=18245000, E=12. However, I would estimate around 90% of the wavefront exponents don't need P-1 done by the person doing the PRP test, since someone else has already done the P-1 factoring.

Agreed, although if doing GIMPS work, I would like to get involved somewhat in the project, rather than just pay the electric bill on a computer that runs 24/7 for GIMPS work, but only needed to run 7 hours per day for actual work.

I appreciate that, but I'm a member of several groups with thousands of members, and I'm yet to find a group with such an aggressive tone as this one. I was particulary annoyed when I see chalsall make a nasty comment towards me, and Prime95 comment on the very same subject (issues building mprime as no makefile for assembly code), yet say nothing about chalsall's. If the leader of the project does not pull up chalsall, then the project is not for me.

I appreciate that, although I could work out a way round it myself. I'm still not sure why it actually happened, as it could be one of three things that triggered this.

Yes, I'm aware of that. I'd already added chalsall to that list, but he was not the only one, although the most abusive of any.

Yes, I accept that. A similar, but certainly not identical, point was made to me by retina in some post.

I have concluded that chalsall is just plain arrogant. Someone else contacted by PM to say "Just ignore chalsall, he's an arrogant asshole that likes to insult people. I guess he is immune to criticism because he runs the "GPU to 72" thing " What I find disturbing is that George is aware of chalsall's behaviour, and just ignores it. If running this "GPU to 72" project allows chalsall to get away with such abuse, then the project is not for me.

I was going to terminate all mprime instances on all computers. However, on a couple of machines where I pay the same amount each month, irrespective of the CPU usage, I will keep mprime running. However, whereas I used to submit an average of a little over 1 PRP test per day, it will now be one about per month, so a 30x reduction in throughput.

I always run PRP or P-1 on my CPU and TF on my GPU at the same time. It slows my CPU down only around 1~2%.

What a pity!

Your computers, especially your huge memory, help the project a lot.

Anyway, you can still get Cat 1 assignments, if you have at least one computer that gets them. As long as you have the AIDs in your hands, you can exchange your assignments between workers and computers.

But it depends upon the size of your USB disk. For LLDC, it's very easy (the save files are only 7MB each). For PRP with proof, the interim residue files are sometimes too huge to transfer in USB disks. You may have to use a smaller proof power, such as 6 or 7.

He is not immune. Just because you don't see in public him getting a stern talking to, doesn't mean it isn't happening. There are things that go on behind the scenes that you don't see or know about. Always feel free to PM in of the mods in red about issues.

And I have concluded that you are a snowflake. Unique, but not particularly special. And quick to melt.

I find it very interesting how words appear to have hurt you so much.

Grow a pair, mate.

My apologies to all forum readers.

The moderators have done a dismal job maintaining a friendly tone in this and other recent threads. We will try to do a better job in the future.

I ask all members to please return to less antagonistic postings. As my parents used to say, "if you don't have anything nice to say, don't say anything at all."

I'm closing this thread. Let it stand as an horrid example of how threads can quickly devolve when we treat fellow members in a less than respectful manner.
