[QUOTE=VBCurtis;586772]Why are you trying to make P95 do what LLR is designed for?[/QUOTE]

cllr.exe is 40% slower than all this.

cllr64.exe version 3.8.23 with gwnum 29.8 is same speed like P95 but Paul is spooking me it has no Gerbicz.

p.s. 40% slower systematically over all 12 processes cllr.exe so 'average'. Really every proces.

and in windows scheduling by hand i didn't figure out how to do this clever - right now i do it by tons of mouseclicks for each proces. I give each proces its own socket which gives optimal speed normally at such intel 2 socket box.

Per the whatsnew.txt that ships with mprime / prime95, v29.4-v29.8 have GEC but not proof file generation.

They are about 5% slower than the current version. I see no point using them.

Obviously trying that now and then measure speed diff with old 29.8

What hardware are you benchmarking this on?

On my laptop AMD R7 4800H @4GHz, 8G*2 DDR4, and 512G NVME SSD.

Ah yes AMD - i believe you directly. "only 5% speedwin" would be little then.

cllr64.exe version 3.8.23 gwnum 29.8 looks identical in timing to latest P95 gwnum 30.6 at my
Intel Xeon e5-2699 v4 ES, 22 cores a cpu, so 44 cores in total.
Under full load runs 2.0Ghz and eats 360 watt measured at the wall (additional gpu power used not measured if you go move with mouse graphics a lot as i let it just calculate).

With watercooling of course keeps cpu cores at 50C here.

Modern processors eat easily 10-20% more power when running far above room temperature (or far under room temperature).

Just migrated from 29.8 to 30.6 on Win64 for some of my PRP tests.
Is there a definitive way to disable proof generation?
This solution:
[code]WorkerDiskSpace=0[/code] doesn't disable it and every couple of minutes (ca. 2) I get a new "residue file" > 512MB.

Try ProofPower=0

[QUOTE=Prime95;586843]Try ProofPower=0[/QUOTE]
I tried putting it both in local.txt and prime.txt, but it doesn't work. Residue file is still being created+updated frequently.

Avoids massive amounts of files here!
Makes things more workable here! (the WorkerDiskSpace=0)
