Formula-BOINC Sprint #13 31st Aug-3rd Sept 2017

Postby UBT - Timbo » Wed Aug 16, 2017 11:39 pm

Hi all

And a week after the 12th Sprint is the 13th Sprint... ;-)

So, keep your caches low, as on Weds 30th Aug around 11pm BST, we'll find out the chosen project for this Sprint.

regards
Tim

Hi all,

So the 13th Sprint Project is: "SkyNet POGS - the PS1 Optical Galaxy Survey"

which is basically a CPU-only project.

Plenty of WU's available so grab a stash - set cache to maybe 3 or 4 days - then set your Boinc Manager to "suspend network access" - and then re-enable it tomorrow night after 11pm.

All the POGS work you then crunch between tonight and tomorrow night will then be uploaded and will hopefully count towards our teams Sprint total on Sunday night.

regards
Tim

Hi Mark

Glad you got a few... :-)

The actual POGS tasks seem to be of variable length - I have some expected to take abt 30 mins, others between 50 mins and 1 hr 10m and quite a few more that should take 2hr 20m or so.

I'm not sure if the credit system they use is proportional to the expected time to completion, but I would hope it is ;-)

If I can, by tomorrow evening, I'll hope to have the 32 core PC running :-)

regards
Tim

Cache loaded and running.

I notice that 3D Now have a RAC of 260K compared to our 70K. Seems like a fair fight :-)

Hi Tim,

Managed to snag 4,165 of them in the end :D

Judging by the results reported by others, it seems to be pretty linear. Also the predictions won't be too accurate until you've crunched a few.

The more the merrier, the top hosts are all Xeons running at 2.6 - 3GHz so you should fit in quite nicely. It appears number of cores counts for more than pure speed.

Hi Chris,

Sounds like a challenge to me :D Besides, just think of the room for improvement we have!

Hi - I won't be able to take part in this one - you can blame Timbo! If it's any consolation it's pouring down here!

Hi Mike,
That's a shame, still, I'm sure it's better being on holiday even if it is raining! :auto-camptrailer:

Have fun,

Huh?

"Why's everybody always picking on me?"

I guess that TeamViewer didn't/couldn't work then ?

regards and hope you enjoy the rain - I had put in a word with "him upstairs" to make sure you felt "at home", on holiday !!

Hi Mark

32 core Xeon now unboxed and re-commissioned :-)

115 POGS tasks now being crunched, but that was simply down to me setting a low-ish cache setting...as I didn't want to download lots of tasks and find they were corrupted or had issues.

Will let the Xeon PC stay offline for now, and once the first few are uploaded after 11pm tonight, I'll increase the cache, grab some more and then (probably) go offline until Sunday afternoon and upload all the results then ;-)

regards
Tim

Hi Tim,

Good news :handgestures-thumbup:

I thought about staying off line but thought that since there's a quorum of two on each task, they need to be validated once they're returned. Fine if you're the second person returning the task but not so good if you're the first person and then waiting. Best to give them the maximum time to validate so stay online.

Then I had a second thought that if you're the second person then it doesn't matter when you return them and if you're the first person and your wingman doesn't return them in time then you've lost out either way. So go offline.

Then a third thought, what if they're re-sends and the original wingman returns them before you're back online? Stay online.

It got a bit confusing after that, the late night and alcohol didn't help.

Eventually I decided that since I'm away until Monday night then I wouldn't be here to bring them back online on Sunday so what was I trying to figure it out for?! Only one choice, stay online :)

Hi All,

Twelve hours gone and not a bad position to be in.

Code: Select all

Pos  Team                  Points      Score      Recent RAC   Overall RAC
 1   Gridcoin              25         1,756,826   146,593      146,402
 2   SETI.USA              18         1,137,463    66,987       94,789
 3   Czech National Team   15           378,300    17,688       31,525
 4   BOINC@AUSTRALIA       12           287,599    16,124       23,967
 5   UK BOINC Team         10           181,096    10,359       15,091
 6   Dutch Power Cows       8           146,761    14,130       12,230
 7   Planet 3DNow!          6           119,502     6,363        9,959
 8   SETI.Germany           4           113,626     8,659        9,469
 9   USA                    1           107,261    12,304        8,938
10   Rechenkraft.net        2           106,344    10,071        8,862


As can be seen from the drop from overall RAC to recent RAC, quite a few teams were stockpiling work :)

As can also be seen by the opposite change, some teams weren't and are now trying to catch up.

Gridcoin and S.USA are way out of our reach but the Czechs and the Aussies might just be catchable. Need to keep an eye on the Dutch Power Cows coming up behind us.

USA should go up a couple of places but at the moment, it looks like the only direction for 3DNow! is down. It would have been good if neither of them scored any points but so long as we score more than both, it's better for our placing in the overall table if 3DNow! get the lesser amount of points.

I'm away for the weekend so last status report from me until it's all over.

Code: Select all

Pos  Team                  Points      Score      Recent RAC
 1   Gridcoin              25         2,457,709   150,668
 2   SETI.USA              18         1,548,323    75,450
 3   Czech National Team   15           562,380    41,318
 4   BOINC@AUSTRALIA       12           348,937    12,461
 5   UK BOINC Team         10           232,616    10,992
 6   Dutch Power Cows       8           199,422     9,620
 7   Planet 3DNow!          6           164,315     7,376
 8   Rechenkraft.net        4           159,140     9,821
 9   SETI.Germany           2           158,975    11,669
10   L'Alliance Francophone 1           158,804     8,517


Completely wrong earlier, 3DNow! have held onto their position while USA have fallen.

A bit of a charge earlier from the French and a slightly smaller one from Rechenkraft recently has moved USA out of the points completely but only just. Eighth to eleventh places are only separated by 3,283 points.

Definitely not going to catch the Czechs and the Aussies look unlikely as well. A bit of consolidation then.

We're just about holding the Dutch Power Cows off, almost identical hourly rates but we're usually very slightly higher. It appears we both might be edging away from the lower table fighting leaving a straight race to the finish line.

Time will tell though, we've been caught within sight of the finish line before so no letting up!

We are now (Sat 1:50) 74K clear of the Power Cows so I'm quite optimistic. We do seem to be slowly extending our lead. However, the Power Cows do have some very heavy bats if they should choose to join the fracas.

Our lead is down to 43K and shrinking fast. Rechenkraft are mounting a substantial challenge. Anyone got any spare horses?
