So how many are going to run the TDP in PG? Looking at my local weather I'm going to need the added heat from some GPUs!

Currently, the fastest opportunities to find Top 5000 primes is with the PPSE (LLR), and GFN-16 (65536) projects. Of course, should someone find a prime in the mega-prime searches, this would certainly give them a good shot at the green jersey. Not a guarantee, however, as in 2018 there were several mega primes found in the Tour de Primes. Overall, in 2018 we averaged close to two mega primes per week for the entire year, so you might need more than "merely" a mega prime to take home green. In 2018 there were 16 mega primes found during Tour de Primes.
GFN-16 is GPU, but PPSE is CPU:

<app_config>
<app>
<name>llrPPSE</name>
<fraction_done_exact/>
<report_results_immediately/>
</app> <app_version>
<app_name>llrPPSE</app_name>
<cmdline>-t 4</cmdline>
<avg_ncpus>4</avg_ncpus>
</app_version>
</app_config>

I suppose I should have said I am testing and tuning. Moved my machines downstairs and the GPU temps are amazing LOL . I even (my machines) found a prime (sadly before the challenge though) largest one they have gotten since running PG!!

I'll keep running PrimeGrid on a GPU or two to help our FB efforts while the cold weather permits.

Hehe, I have a rig in the garage that has amazing temps as well. I get a minimally-heated garage out of it as a nice side effect ;)

Way down here in 10essee, I've had to keep my window shut for nearly a week now. I am hoping that trend continues. :) Makes me feel better about running so much gear when it's still a touch chilly inside.

Even though I am testing and tuning it still frustrates the even living hell out of me with the crunchers that are running endless errors. <RANT> I have a machine that was throwing errors and I FIXED it so it stops the errors. I have a total of 4 errors (out of 6100 tasks) vs some clown that has 2 DAYS worth of continuous errors FFS and WTF!!!!!! Then you have the ones who have sat on them for days and decided to abort, along with others allowing them to time out. GYHOOYA, either play the game or shut your sh!t off!!!!! <END RANT>

I must have too many computers. I have to leave almost all the windows open, even just above freezing, just to stay below 75f inside ! And I have 3 turned off to help the electric bill.

Well I had everything tested and tuned, still working on the troubled machine though. I fired everything back up since it has gotten a little chilly here, honestly the first time I have used crunching to help my furnace keep the temp up in my basement. Current temp is -25F/ -32C, going lower tonight even, I'd have to research but I believe this is the coldest I've been through in my 5 decades of existence.

@emoga ummm you can have your Canadian weather back!!! My house is popping and creaking from the cold, kind of freaky to say the least.

Good Golly that's cold. It is a full 50F warmer just 2.5 states below you. My windsheild washer fluid is only good to -20F. :oops:

Prestone anti-freeze says: "Protection... from -37°C to 129°C." If it gets much colder tonight, you might have all sorts of repairs to make back at the shop for busted hoses, radiators, reservoirs, but hopefully not blocks.

Yeah but it will be good money hehehe.
Looking at the upcoming forecast:
tonight's low is -32F/-36C and the windchill is going to be killer again,
Monday: high of 42F/5C chance of rain LOL no one can say I do not live in an extreme weather area.

Probably be no work again tomorrow, service truck gelled and a check engine light for the DEF system. Brand new truck with 9k miles on it...............

Must be a Ford. :p

I don't imagine these temperatures happen often enough for your area to run 70/30 Glycol/water?

House popping/creaking would scare the, uhm, crap outta me.

Nope! it's a new Ram w/ a cummins!!!
Nope on the temps too, everyone still runs 50/50 around here. Last record was -27F in 1982, some of these youngsters here were still a twinkle in their parents eye. :laughing:
Popping and creaking, bah nothing to worry about. Just the house settling......... ah yeah that's it....settling.

Thanks, with my luck I won't get one all month...then maybe 1 hour after the event is over ;)
Same boat here, shot a prime on the 29th.........I hadn't seen one since last years TDP.

For anyone interested in the Tour de Prime Challenge:

Challenge Thread

Primes Found/ Stats

Double Check/ Hard Luck Stats

Both @emoga and I have unfortunately made the DC/ HLS stats board.(I am 2nd place there, so am I the 2nd 2nd loser?? LOL) We need to flip it around and get on the other stats list!! (or others on the TeAM who are "playing" need to find a Prime) On the DC my machine ran, It downloaded it 14 secs later and was beaten by 12 secs uploading. Although my machine finished it 75.5 secs faster it was too little too late!!

Basically slower machines on this are at a BIG disadvantage. One in one hundred come in as 1st. I'll be moving on to something else.

@emoga, I see you have a couple primes now in the TDP. Congrats! :)

I'm estimating I have an 80% chance of getting one myself.

Not sure if I should switch over to PPS-MEGA and GFN-17-Mega to go for a mega prime or not. All or nothing approach.

Is anyone else running mega's?

I was running megas for the entire month of January. Assuming I come up with a regular-sized prime this month, I plan to switch to megas again.

Congrats to emoga!

Congrats(?) to Mattozan for being the DC.

Teachable moment courtesy of <name removed to protect the could-have-been-prime-finder>: If your computer is failing on every GPU task, either fix it or turn it off. The first task in this workunit was his, but the task errored out like the 3000+ other GPU tasks on this computer.

It will be about 12 hours or so before the processing on this prime is completed. (Technically, it's still a PRP right now.)
Congrats, @emoga! Arrgh, and I haven't even found a smaller prime yet!
