PrimeGrid Leonids Challenge Nov 17

[Ken g6]

Welcome to the PrimeGrid Leonids Challenge. Like a Leonid meteor, this challenge will appear suddenly, burn brightly, and be gone before you know it. So don't miss it!

What you need:

• One or more fast x86 processors. (Even slow ones will do!)
• Windows, Linux, or MacOS 10.4+. (Linux or MacOS 10.5+ may be up to 20% faster, this time only.)
• BOINC, attached to PrimeGrid (http://www.primegrid.com/).
• Your PrimeGrid Preferences with only "Sophie Germain Prime Search (LLR)" selected in the Projects section.

What won't help (but won't hurt either):

• A 64-bit OS.
• A large amount of RAM.
• Any video cards.

This challenge starts November 17 at 18:00 UTC, and runs for only 24 hours. Work not downloaded and uploaded within the challenge will not be counted. Should you not be able to be in front of one or more computers at that time, just set their queue level very low (0.01 days). This also makes it more likely that you will be a prime finder rather than a double-checker.

Welcome and good luck to all!

I'll be in!

 

[petrusbroder]

I`ll be in too!

 

[zzuupp]

[Philippart]

I'm in!

I already found a Sophie Germain prime, let's hope a one day crunch will give me another

Technically, you found a Riesel prime in the Sophie Germain search range. If you had found a Sophie Germain prime, they'd be looking for a new range to work on!

 

[SlangNRox]

Count me in. Recruited my friends core i7 to help out for the race

 

[RobertE]

If I setup my events in Windows task manager correctly, both my boxes should switch from Einstein to Primegrid 1 minute after the start of the challenge.

Fingers crossed.

You all may find this useful to avoid that last minute flush of WUs. On linux, I put this file in the BOINC folder which is in my home directory.

file name: cc_config.xml

contents:


<cc_config>
<options>
<report_results_immediately>1</report_results_immediately>
</options>
</cc_config>

PrimeGrid website is down?

I'm getting this on Chrome/linux:

Fingers crossed.

[petrusbroder]

Got sufficient number of WUs for all 16 comps taking part ...

And we're at a good ranking, too. Let's stay there, or better yet, go higher!

 

[petrusbroder]

Yeah, looks good.
Sorry, I got a late start!

 

[djdave404]

well petrus, ya passed me up,

Biodoc is running 24 cores, i'm running 18 cores and 24 threads.

it will be intresting to see if the virtual cores will keep up with the real cores.

where the last race was core dependant, I'm intrested to see if speed plays a bigger part than the number of cores/threads per task.

i must be a geek, i think it's fun........LOL

Go TeAm AnandTech!

 

[filibusterman]

Just saw this Ill be switching over asap

 

[djdave404]

Just saw this Ill be switching over asap

Thanks, The more we have on it, the better our standing will be.

If someone else is reading this and has not joined yet, it's not to late.

We are very close to being in the top 10! you can help us get there.

Go TeAm AnandTech!

 

[RobertE]

Looks like everything switched over as planned. :awe: Using task manager makes things much easier, if of course, you remember to turn the tasks on.

 

[djdave404]

Well i have been doing some tweeking.

I have both i7's at 4.0 now.

the 920 took removing the side cover and useing a house fan to blow air at it, but it's keeping the temps at an acceptable range.

Took it from 3.4 to 4.0, and wu's went from 17:45 to 15.05 to complete 8 WU's.

or every two hours or less i will gain 8 extra WU's completed by doing this.

The 980X @ 4.0 is taking 15:20 to 15:30 complete 12 WU's

i have not checked the AMD 940 @ 3.0 or the Q9450 @ 3.0 yet for times, but i can't do any more with them anyway. it is what it is for them...

(Edit: The Q9450 is turning WU's over @ 11:30 Per.)

I thought some may like to compair notes on what can be done for the race....

And yes, i'm having a good time....

Go TeAm AnandTech!

Unfortunately, I only have 18 cores, 3 ageing quads and a new AMDx6.

Go TeAm!!!:thumbsup:

 

[RobertE]

i5-750 ~9.5 minutes per wu
C2D-6320 ~14.5 minutes per wu

Ah, well your AMD X6 is listed twice.
My mistake.

I wish you had two tho....
