PrimeGrid World Maths Day Challenge March 1

[Ken g6]

Well, I still don't know the whole PrimeGrid Challenge schedule. :| What I do know is that there's a race coming up in less than a week!

What you need:

• One or more fast x86 processors. (Even slow ones will do!)
• Windows, Linux, or MacOS 10.4+.
• BOINC, attached to PrimeGrid (http://www.primegrid.com/).
• Your PrimeGrid Preferences with only "The Riesel Problem (Sieve)" selected in the Projects section.

What would help, but isn't absolutely necessary:

• A 64-bit OS on a 64-bit processor will run 70% faster than a 32-bit OS. So, Peter, that means you have less than six days to get a 64-bit OS installed on all your machines.
• Downloading a few WUs early. This project has a large (35MB) one-time sieve file to download.
• Reading [post=30943822]Ken's WU Juggling Guide[/post] and applying it once you figure out how long each WU will take.

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

• A large amount of RAM.
• Any video cards.

If you're running a 32-bit OS on a 64-bit processor, there are three ways you can run a 64-bit OS for this challenge.

1. Install a 64-bit OS as your primary OS.
2. Install a 64-bit OS as a secondary OS. Wubi is the easiest way to install 64-bit Ubuntu Linux alongside 32-bit Windows.
3. Install a 64-bit OS on a virtual machine in VMWare. This may not work, depending on your processor, and even if it does work it may be slower than the other two methods. However, it's less intrusive than the other two methods.

This challenge starts on 1 March 2011 at 18:00 UTC and runs for only one day. Only work downloaded and uploaded during the challenge will be counted. Should you not be able to be in front of one or more computers at the start time, either set their queue level to zero (0) days or try one of the scheduled start method from the strategy thread. Network connection time options may also be useful - though they depend on your computer's clock being correct, so set the start time a few minutes late.

P.S. If any of you know some kids interested in math, you might point them to the other World Maths Day site. (Flash-heavy site!)

Welcome and good luck to all! :thumbsup:

Bring it on.

...A 64-bit OS on a 64-bit processor will run 70% faster than a 32-bit OS. So, Peter, that means you have less than six days to get a 64-bit OS installed on all your machines.

Or tortoises like me will pass you by!

 

[petrusbroder]

That is OK ... I'll see what I can do! I think I may have some comps ready with Ubuntu 10.10 ...

 

[biodoc]

Ready with 64-bit Ubuntu 10.04 LTS (long-term support)

 

[rabrittain]

This is a damn good idea!!

 

[rabrittain]

ok -- I'm ready.

 

[petrusbroder]

I'll se how much I can contribute ... to much to do for changing OSes.

 

[filibusterman]

this should be tricky with the start occurring during work. On my work computer looks like 4 hour wu. Maybe Ill give the ole network usage allowed clock a trick.

 

[ZipSpeed]

I am prepping to get at least one mahine into this race.

 

[petrusbroder]

15 computers are ready ... 5 of them sporting a 64-bit OS ...
All of them 2 - 8 threads, which gives a total of 80 WUs crunched at the same time.
It should add ... some of cores crunch a WU in 7.5 hours, others crunch them in 3.5 hours ... we will see how much this will add.

Start in 3 minutes!

 

[filibusterman]

set the network connection time here at work and it started when scheduled so hoping the rigs at home will be downloading shortly!

 

[petrusbroder]

All comps got WUs!

 

[ZipSpeed]

Got my WUs too. :biggrin:

 

[rabrittain]

. . . , up and running -- the race is on!

Not bad. But see, Peter, someone's beating you!

Edit: I should look before I post. That was some jump!

 

[biodoc]

I don't have a chance vs. Petrusbroder!! :biggrin:

kimmyl just blew by me! :thumbsup:

Thanks for the stats guys!

 

[ZipSpeed]

I just added my Q9550 into the race. Would have done it earlier but just got home now.

[petrusbroder]

Some of you will probably get past me ... I only have 16 cores with 64-bit OS ... I got to change them all ...

I only have 2 boxes with x64 and they get a mega advantage!! I for one wont be passing you up

 

[filibusterman]

and thanks petrus for the stats!!

 

[biodoc]

kimmyl and I are in a tight race!

EDIT: filibusterman is coming on strong! 3-way race!

great crunching everyone! :thumbsup:
