1) Message boards : Prime Sierpinski Problem : Weird Sieve WU (Message 22383)

I noticed that too, its the oldest unfinished WU. It looks like something has gone terribly wrong with that host.

The latest version of Ubuntu is v.9.10

http://www.ubuntu.com/

Thanks, updated.

Is anyone able to confirm that the "power save feature that throttles the CPU frequency down to save power" section in the first post is still valid or should it be removed now??? Thanks in advance!


I can confirm that Ubuntu 9.10 automatically steps to full throttle when running BOINC. However, 8.04 is still the current LTS (long term support) version, so many will continue using that version until the 10.04 LTS release (just around the corner), or support expires in April 2011.

That said, most people running the older release already know about the powernowd glitch and those switching are almost certain to get the newest release. I would suggest removing that section for the next challenge, when the older versions will be nearing obsoletion. Its still valid now at least.

It should be noted that in the newest Ubuntu release, 9.04, the powernowd bug is fixed, and the CPU runs at full speed automatically for active programs at any nice level. Also, BM gets updated to a newer (not newest, but at least no more red message when it starts) version. About time!
4) Message boards : Number crunching : Intel Atom? (Message 14819)

Has anyone tried running a Intel Atom setup here at Primegrid?

Intel used to be "king-of-the-hill" on pure number crunching - and if Atom has adopted that - I migth actually be worth it to run one here.

Have being sniffing through alot of users to see if I could spot one....But no luck so far...

Best regards,

I tried a few PPS llr's a few months back on an Intel Atom. They took well over an hour. And that was when they were averaging 6-10 minutes on most machines. It's just not worth it.

But I think 9 challenges in 1 year is quite much for a single project.

Still theres fewer days of challenge planned for this year. 48 Days worth last year, only 29 days this year.

Wow, I just noticed the turnout for this challenge is terrible. Only 411 on the leaderboard, down from over 2000 on last challenge, (forget the flawed PPS challenge), and over 1000 on the woodall challenge. Is that all because of that charity challenge running concurrently or is something else going on?

From those 411 you cannot say they are really participating in the challenge.
I think many of them ticked all PG-subprojects and got also one or two 321 LLR WU's.
137 of them returned only 1 WU and 61 returned 2 WU's until now in 3 days and 4 hours.

So thats maybe 200-250 in this challenge "on purpose". There seemed to be a lot more "accidental" participants in previous challenges, but also a REAL lot more on purpose.

True, participation is down about 1/3 from previous LLR Challenges of similar length. However, output is up!!!

At least that makes me feel better:)

Everybody CHILL!

Although I do find it a little amusing when every long LLR challenge turns into a street brawl. Seems 3 minute wu's are the only thing that can keep people happy.

The sieves and AP26 all have 64 bit applications. Therefore, the optimized code earns more credit.

Finally, while Challenge points are awarded for each WU, BOINC cobblestones must wait until a quorum of 2 is achieved. Therefore, RAC will go down and pending will go up until quorum is met for each WU.


Never said I was unhappy with the challenge points. I actually expected to be much further down the list than I am:)

Has anybody noticed how lean the points are for this contest
What points?
*sigh*

I have a feeling my RAC is about to take a hit over these next 5 days. And it was just starting to get good with AP26 giving me 3 times what I ask for. At least BoincStats has the lead thusfar :)
