GPU to 72 status...

Sorry. I'm currently under attack from all fronts. I actually find it somewhat amusing.

To share, I was once ~85 feet underwater when my regulator failed. I followed the training and breathed out through the regulator, and only got water back.

I remember very clearly thinking "Oh, so this is how I'm going to die".

And, then, the additional training kicked in: You have an "octopus". You have a secondary air supply immediately available. I used that and survived.

My "buddy" still to this day says "I would have noticed".

At the end of the day, we all stand alone. Be comfortable with, and manage, that.

I rely on, and greatly appreciate what you do and the results thereof.
Many thanks. That doesn't pay the bills, but it is the currency I have immediately at hand.

Ack. And all primes are odd. Give or take 1. (What happens when I get 4 hours sleep.)

Thanks guys. And sorry -- yesterday was a /very/ stressful day...

I finally got off my butt, and implemented a parallel spider which looks at PRP in addition to LL state. Previously GPU72 was not aware of candidates which had a PRP done instead of an LL.

This means the Current Levels report is once again sane, and I won't accidentally bring in candidates to TF which are really a DC.

[kladner]

Can I assume that 1st time LL TF is still the most helpful at the moment?

Also, I ended up sticking another 16GB of RAM in the new machine, 32 total. It's doing pretty well now at DC, but is there a current need for P-1?

Yes, please. LLTF; ideally WMS to at least 74 or LG72D.

And, no. We're _good_ for P-1'ing (at least for Cat 0 through to 2 (currently); Cat 3 and 4 are pointless to chase with P-1'ing).

[kladner]

Thanks Chris. While I thought of P-1 when I upped the RAM, that was not the reason. I was following Mackerel's suggestion that filling the other two slots carries the same benefits as dual rank RAM. This turns out to be the case. LL performance went up about 30% as Mack predicted. CPU still outruns the RAM in the 4GHz+ range.

AT 4GHz a single worker with 6 cores is getting about 2.47ms/it. Faster CPU makes exactly No difference. Same is true at lower speeds, but I am compromising for the sake of other tasks which will be added later. I suppose I could save some electricity for now by running at 3200 MHz, which seemed to be about optimal, with the same throughput as all higher frequencies.


EDIT: Wrong! Running at 3200MHz is slower. I guess it was in other configurations that I encountered the same performance at different CPU speeds.

Just so everyone knows, srow7 pointed out to me that the GHzDays Saved graphs weren't showing the factors found for work done in the 10xM ranges. This has now been fixed.

Just in case anyone stopped doing work because of this...

[chalsall]

Just a heads up...

My DNS provider, OpenSRS, is having some issues with their servers at the moment; this is intermittent. They're working the issue now, but if you see any "can't resolve" messages, this is the reason.

Noticed a weird issue(which may be my fault) - I run P95, running P-1 through the gpu72 proxy... I've noticed that the assignments that P95 is running are reserved - almost all of them(haven't checked) seem to be reserved by primenet by someone else... I've stopped all my computers that are running P-1 through gpu72 for the time being.

EDIT: example: https://www.mersenne.org/report_expo...2310481&full=1
EDIT2: I noticed a lot of them are reserved by "alelele" - is that a gpu72 spider?

Strategic clearing out of abandoned assignments.

These are going to be recycled in mid-February, so your machines which work though the proxy (and have a reliable and predictable production rate) and mine have been clearing out as many as we can before then. Actually, next week I was going to stop giving your machines work to ensure all the assignments were completed before being recycled.
