I thought I torture my laptop with Nvidia K2100M for a while. This GK104, 576 shaders @ 666 MHz, submitted its first WU after 5.5 hours, from which I extrapolate a performance of 160 k PPD. I figure 365 of such laptops should beat Tony's Collatz production.

Day two of the sprint finds us still securely in second, but creeping up on first place. Will we have enough wind in our fans to get by and take first?

Mean while in the Marathon we have picked up TWO places and FOUR points.:eek::D

Way to go peoples :cool:

Today I had some trouble with two separate machines with two different types of GPUs suddenly deciding to generate nothing but computation errors. Updating the driver on the HD 7950 seemed to fix the first, the second, which includes a GTX 1060 from a different errant machine, seemed to respond to a slight downclocking. Perhaps the 500w PSU is not quite up to twin 1060s and an i3, but that seems implausible.

Sorry to hear of the troubles, crashtech. These cards are proven/tested or new additions to the fleet?

********************

@4thKor

Thanks for sitting this one out, 4thKor. You have likely made this a victory for TeAm AnandTech! :D :p

Beercan though...."No.15" worries me with his super low output during this race...where is the other 49M points per day going I wonder?

All tried and true! Either Collatz is a bit more finicky than some of the other projects, the heat is exposing weaknesses in my systems, or both, or ??? They seem to have settled down after the remedies described. Also I decided to temporarily suspend CPU tasks on the machines in question. So one of my attempted cures had the desired effect, but the problem with Sprints is that there's little time to be methodical enough to tell what the problem was. That and I fail to take good notes! :p

A few hours ago, the LHC@home admins reverted the SixTrack validator and moved all WUs with status "validation inconclusive" to "validation pending", and the validator is getting busy now reevaluating all those WUs.
This may take a while. Today = 5 days later I have 6000 SixTrack tasks in "validation pending", and 300 "inconclusive" once again (but 0 invalid).

Thanks yodap. I'm am glad to see the forgotten optimizations being implemented on a few EVGA machines, plus Howdy2u2 joining the party late, have helped EVGA regain 3rd place. I've been fond of your team ever since some friendly banter that occurred a Pentathlon or two ago, when were were neck and neck on POGS I believe it was, and I have had some of your members give invaluable assistance in some project-specific forums as well.

Holy Conjecture!!!!!!!
From 10M down to a win by 110M+.
WHAT A FINISH:)
What a great TeAm we have. Maybe we will get a few converts after a race like that :)

I'm at a loss for words, just :cool: :cool:

Well done all! :D

Having OCN quit on us was like re-living the Siege of Masada. We all run up the hill, swords raised, only to find the gate left open and all the inhabitants having ended themselves already. At least after a brief search, we found some Gold! :)

As a history and philosophy buff, I think your analogy is well placed. Very cool! Rock On..

Anyone familiar with Grid Computing Center?
I am almost to Milestone 100K.

It is a NCI project. It sips unused CPU cycles.
You can run four WUs at a time per BOINC instance. Each WU is worth 10 points and takes ~1 hour. Max of 2880 ppd per BOINC instance. I did like StefanR5R and made an extra instance on my three computers for Collatz Sprint. I am leaving open with GCC running so I can get a max of 5760 ppd. I think the top teams have people running 100s of instances per computer :rolleyes: o_O :confused_old:

Low ram usage (1,004K per WU) and no CPU use shown :)

Edit: mispeeling

FINALLY, all systems are finished and clear of any climateprediction.net tasks. I'll not be doing those again anytime soon. ;) That last batch was sent on June 14th, and finished just a few hours ago.

AFAIU, validation may not necessarily be instantly. The server may still perform some kind of validation by means of some more or less extensive checks. If I recall correctly, Numberfields for example has quorum-1 WUs and performs server-side checks during validation, but it did so quite quickly.

Edit:
Yep, VGTU perform server-side checks. Or did so a while ago, at least.

I have found bug in validator – it was crashing in some cases and automatically restarting until next crash. I've not seen it in my own small tests. Sorry for that, our validator is not trivial, because we want to avoid replication.
