World Space Week Kickoff Challenge Primegrids 7th challenge is October 3rd - the 4th, 24 hours.
Short challenge with short WUs
Start OCT 3rd 18:00 UTC  Ends Oct 4th at 18:00
SGS-LLR WUs, it is LLR so hyper thread should be turned to off.
Only WUs turned in between the start and finish will count towards the challenge.
 
Good chance of finding a prime number, most likely the best chance of finding a prime number of all the PG projects.
 
Set your system to keep no cashe of WUs, you want to finish a WU and DL a new WU.
You do not want WUs sitting on your drive waiting to be done. The first one to turn in a prime WU is the founder.
 
Good luck every one, hope you find a couple primes.

I will be ready !!!!! My New Server Will Be In Tomorrow !!!!!

Very good, right on time. Can't wait to see what that beastly thing can do.
 
I picked up a few PSUs so I should be ready to throw some more hardware it this challenge..
Got to love ebay. Antec Platinum 750W 32$ shipped(refurb like new)
Two unused server pulls Seasonic 650w 80+ for 65$ shipped
And a Antec 650W Truepower for 31 and change. All work great and not a speck of dust.
Seasonics have two 8pin CPU power plugs and are more than enough for my AMD 2P and 3P systems. Plus I bought a couple adapters for the others.
 
Lets give em heck on the 3rd!!

Short and sweet.   I'm in!

I ran a few yesterday with HT off using 3 of 4 threads (75%) and the run times were between 824 and 831 or a little under 14 min.
2600k @ 4000Mhz.

i7-4960X @4200 MHz HT 20 Minutes Running 10 Tasks
i7-4960X @4200 MHz HT Off 14 Minutes Running 10 Tasks
 
Looks like I will run this short run LLR with HT on with the i7-xxxx CPU
 
I will test the Intel Xeon E5-2680 v4 2.4GHz, Turbo,HT,14C/28T before Friday and report back.
 
Results as:
With Turbo On and HT On:
With Turbo On and HT Off:
 
With Turbo Off and HT On:
With Turbo Off and HT Off: 

So Far the Only CPU that I will run with HT is the i7-5960X time is around 15 minutes.
The i7-4960X now @ 4300MHz & HT Off takes about 11 minutes.
The i7-3930K Now with HT Off takes about 15 minutes.
Been having trouble with installing Windows Updates on a new Server 2012 R2.
Been working it all day today.

Bill, I believe an i7-4960x is a hex core CPU, how can you have 10 tasks running for 20 minutes?
 
An Intel i7-3930 hexcore Sandy-bridge @ 4.2ghz with 16gb quad channel 1866 9-10-9-25 memory
11.87 with HT off.  Six WUs crunching
25.25 with HT on   Twelve threads crunching.
 
Seems like HT off is the way to go.
Plus that extra 11-12 minutes doing the WU maybe the difference between being founder and double checker.
 

I have HT On so that give me 12 Threads. (6 Cores 12 Threads)

I plan on running a couple cores for this challenge since it is short and sweet.

This Which one is Better, any BOINC Users have an Idea?
 
   Programs                                                           OR      Background services

 
On know on Windows Server OS Background services is the Default and on Windows Desktop OS Programs is the Default.

Programs of course. Boinc is a program and so are the tasks. If you're primarily crunching, it makes sense to do program focus. Or are you actually using it as a server? Depending on the services you're running, programs is still the better choice as unless you are running lots of actual server components on that system.

That is what I was thinking BUT, the Client is the Program and the Task?
The running projects are what I was thinking are not really a program but thanks.

From some quick googling, it makes no practical difference. Also the tasks vary in whether they are service threads or regular processes. Boinc has a page that says as of version 6 it installs as a service, but looking at process Explorer some tasks are run as services under svchost while others run under explorer.exercise so wouldn't be able to start until there is a login.

TLDR: it probably makes no difference. I doubt there would be much contention for resources anyway given the use case.

I installed Sindows 10 on my T630 and it worked fine.
I want to test to see if a Non-Server OS Runs the same or Better than a Desktop OS.
With Performance Set to Programs.

I'm Ready

 
Some timings on Xeon E3-1245 V5 @3,5HGz
The two examples are both with HT/ ON, but the bottom pic is with 50% Cpu usage.
(Kinda HT/ Off simulation for lazy guy's like me )
Seems I can go with HT/ ON on those WU's.
 
Ahem, stuff got messy when uploading pictures.
Bottom line, with all cores running, the time was 17 mins avg.
 
 
 
 
 

Thought it is a 24hr challenge??
