Finally the CPU market regained some sanity --- but RAM prices plainly hurt, flash memory remains expensive too, and the red part of the GPU market is pure weirdness right now...

All I can say is that is was a long day yesterday, and even on a good day, I'm rather easily confused.

Right, GCW-LLR is the one. Check this one as the only CPU project at www.primegrid.comYour accountPrimeGrid preferencesEdit PrimeGrid preferences:

Then don't forget → Update preferences at the bottom of the page...

Here is a C:\ProgramData\BOINC\projects\www.primegrid.com\app_config.xml example to enable multiple processor threads per task:
Code:
<app_config>
    <app>
        <name>llrGCW</name>
        <fraction_done_exact/>
    </app>
    <app_version>
        <app_name>llrGCW</app_name>
        <cmdline>-t 4</cmdline>
        <avg_ncpus>4</avg_ncpus>
    </app_version>
</app_config>
I tested 1-, 2-, 4-, 7-, and 14-threaded tasks on 2x14 core Broadwell-EP with reg-ecc 2x4-channel RAM. 2 or 4 threads per task look to be the optimum for throughput, judging from average task durations. I am still waiting for more tasks to get validated in order to check throughput in credits/day. Processor time per task and credits per task are somewhat variable.

I guess the amount of processor cache, maybe in relation to RAM speed, play a role for the optimum thread count of the LLR applications.

Timing seems to vary. I've got one running on what's in my sig, and it's aiming at 2:10 running one WU on all HT cores (8 threads). My laptop is running one that's aiming to take over 12 hours!

Tomorrow at this time the picture will look much different, when all the contestants who run without "-t" parameter have begun submitting results.

Delayed a little because I was watching the eclipse. Stefan's down to 3rd, and the TeAm to 5th, but we're more than double the next team. :)

Still a good lead on EVGA, largely thanks to Stefan, who's done more than all of EVGA combined! :)

Thanks Ken, 17 hours to go on PG, so I've suspended getting new tasks. I hope it's not premature.

Formula BOINC gets announced in about 24 hours!!!! :D Hope it's not GPU (due to SETI). :/

Yeah, @bill1024 selected the right subproject in the web prefs for this challenge, but must have made a little mistake when selecting the team affiliation. ;)

(bill1024 is currently tenth on this list.)

@TennesseeTony , @crashtech , looks like it will be down to the wire for you two!

I don't think Tony is trying that hard! I've pulled a couple out of production already since they were going to take too long to finish. The Westmeres in particular are obsolete for this project.

Heh, that's a win by a single WU. Validations are still proceeding, so the jury is still out. ;)

I checked the PG stats page first and was (sorta) disappointed to see I only finished 20th, but then I saw who was in 19th and giggled a bit. :D Good job all!

I did lose one box due to a Winblows update, it never showed up again in my TeamViewer list. I haven't had the gumption yet to turn off and unstack all the computers in front of it to attach a monitor and see what the heck is going on with it.
