This is the POTM for August, it is primegrids 4th challenge of their series for 2017
It is from August 20-23rd. 3 day challenge, if you want run an extra day or two to help with clean up and make it the full 5 day POTM. Up to you.
What every you want to do, any and all help is greatly appreciated.
Here is the PG challenge page  http://www.primegrid.com/forum_thread.php?id=7540
This PG Solar Eclipse Challenge this is a CPU LLR  Sub-project = Generalized Cullen/Woodall Prime Search LLR (GCW)

As with LLR tasks, watch CPU temps if you're overclocked, AVX and newer instructions are used so newer (Sandybridge +) CPUs will run even warmer.
So it is best to run with Hyper Thread off if running one task per thread.
These are long running tasks, website says up to +- 24 hours with one task per thread,
Would be nice is we could keep our 5th place spot we come in often, will see how it goes
It is Summer and the weather is warm, and the living is easy.
 
Going to run some tests single, and multi-threaded tasks and see what is the best way to go about this project
 

Thanks for the heads up - I personally prefer Santeria - But I am all in -
I hope yodap throws a rock at my head to remind me.

Taking aim!

CPU = Summertime or is it Summertime = CPU.
Any Hoot I am ready.
It is 70F in Lemoyne, NE and it should be in the Upper 90's Lower 100's and it is raining like Cats, No Dogs Yet!

Is the electric more expensive where you are now, or need for more A/C?
Why do you think the bill went up?

The power is more - i used to run up the ac but I now have water cooled cards and the 2 that are not are in an enclosed room attached to the house. Everything costs more here. Water, power - the rent now that I sold my house we are renting is insane. The ac in this house is much newer and runs far less.
And this is no castle - it's nice just the area in general. I am on an island.
The houses on the water have large boats, pools, solar panels. This is a cool place - no traffic, until you want to go to Tampa next door.

The single core units take forever if you run 100%. Thanks Bill I'll try 4 on my quad core. Do  you know yet if there is a points advantage for multi-t?

My first test was on 2500k, no ht. I've since started an 8 thread wu on the 2600k @ stock speed, 59% in 2 hours.

Hi Steve, I do not remember how many CPUs and core/thread you have. What do you have?
If you have 4 CPUs, I would run 4 - 10 core tasks. If it has 2 CPUs, run two tasks.
You want to run 1 task per CPU.
Reason being, you want the task to stay in the CPUs cashe and not have to use much if any system memory.
If running too many tasks, it will not fit in the cashe of the CPU, onboard cashe is faster and is right there in the CPU.
My CPUs have 12mb if I remember right, if you have 20mb or more, you maybe able to run two per CPU
My 2P e5-2670, I will run two 16 threaded tasks. 2 CPUs with 8 cores 16 threads ( I think) I have to test 8 vs 16
Depends on how well it scales. The 12 threads were better than 6 cores.
 
You can try different configurations and see if it is faster or slower.

Love it when you guys talk about your big guns

Ran some tests with bcavs setup, 6 core tasks.  Everything looks good, about 14 hrs on E5-2670's.
 
I didn't try 2 x 16 core since I wanted a little buffer for GPU stuff.

OP edited to show the time it starts, I guess that is an important thing to know.
I'll let you know what times it ends too since I am in a good mood.
 
The challenge will begin 20th August 2017 18:00 UTC. It will  end 23rd August 2017 18:00 UTC

24 hours to start.
Starts 2PM Eastern USA time, Sunday 8/20/2017

Just started my main rig on some task to see  how they do.  Thankfully all my OC cpu's are on custom water loops.  I'll bring some of the other system online tomorrow.  Looks like ~9 hours per task on my 6850k with HT off.

You may want to run these multithread, using the app_config posted up above. Try and see how it works for you.

I just hit some tasks up, says not finished for 5 days.....
 
Am using Bill's config file..... but will not finish any before end of challenge at this rate.. Not any Blame on Bill at all.... no flames...
 
Is this normal for these tasks? anyone else seeing the same??

How are you guys making out? Get it sorted Steve?
I am sure you should not be taking days to do tasks if you are using multithread 1 task per CPU.
Mine seem to be doing ok so far, just added one more 12 thread to the mix.
We'll see how it goes, going to get hot again here tomorrow, only real hot for one day.
