BOINC Pentathlon 2024

[GOTSpectrum]

I've reached out to LMG to try to get another shout out and also jake is going to throw some hardware at the marathon

I still don't understand why it values units from my desktop so much less with the CPU time completely wrong...

 

 

 

It looks like your CPU time is significantly less than your run time on those units. Do you have CPU time turned down in your BOINC client settings? Or maybe is it only set to run when idle?

No, CPU time is at 100%, and the units complete in the time you'd expect them to, it's just the reporting that's out of whack...

I'm thinking it might be because of the P/E core shenanigans, all units complete in about the same time so Windows must be moving them around between both types and that probably fucks up the way they measure CPU time? I've just tried downgrading to 16 threads only and forcing it on P cores, will see if it gets better... eventually given the long validation times

Looks like Sidock's out for being hosted in Russia and thus not being accessible for the very active Ukrainian team, replacement probably announced on Sunday...

[GOTSpectrum]

jake should be getting around 400 threads on marathon for a few days 

[GOTSpectrum]

amazing guys another record update of over 55k points

Oof that sounds possible and extremely unfortunate if so. I have read cases where CPU vs actual time was out of whack and sometimes a reboot would help, but those were the opposite of your case where the CPU time was longer than the actual time. But may be worth a shot if you haven't done the obvious already.

 

The credits granted is based on the CPU time so definitely why your credits are being affected.

 

Maybe you can try using Process Lasso to keep the jobs on the performance cores?

That's what I've done now, they clearly complete faster in about 26 mins vs 31, don't have results yet but it seems even process lasso itself is seeing wrong CPU usage values. Seems it might be a way of getting info from the OS that's broken and that's what their program is using? If so not much I can do, but then my most powerful machine is giving out worse points than my 25W laptop, almost not worth running it at all

 

EDIT: that's been the same across the past 3 days, and the machine was always shut down at night so it got its reboots

Decided you join you guys this year

84 cores total, some seriously fast (7950x) some rather slow (9700T), but it should all help

 

I'm not sure what to do about all the pending tasks... I have over 2k Ramanujan tasks pending. Hoping that quorum will be reached for those when people drop in with their bunkers?

That's the hope, many of us are in the same boat

Also 84 cores??

 

Aye they all hyperthreaded?

Depending on how long the jobs take to validate you may not see much yield right away but if process lasso doesn't give much improvement, I wonder if disabling the e-cores outright in the BIOS will? I haven't had a newer gen Intel in a few years so I'm not personally sure if that's possible, just throwing the idea out there.

84 cores, running everyting single-threaded. (Using 50% of cores setting in BOINC). I've been doing Primegrid for years, that's the way we run thing there usually as it's the most efficient, I assumed it was the way to go for the current challenges too?

 

I have a rented Epyc with 32 cores and a rented 9900k with another 8 for a project that makes up a good chunk of these - They are not doing much at the moment, but not sure I can use it for the entire 10 remaining days.

Ramanujan does benefit from hyperthreading from what I can see

Even without validation I can see the CPU time column is still wrong...

Might try disabling the E-cores but it's my main machine I'm on right now, would kinda suck

Sitting on a couple hundred NFS@home to drop when I wake up in the morn

[dogwitch]

me what got and jake get into the mix...

sir could i have some spare cores ..... please.

Thank you. That added another 56 threads

It does suck a lot, who knew 16 fewer cores would be apparent when multitasking a lot...

 

And Process lasso still sees the wrong CPU usage so RNMA probably will too

2nd Jav throw date has been announced: 12-13 May 2024 00:00 UTC. Probably suggest we give this one a try if we aren't going to be able to gain any places in City Run. Otherwise skip and then do the last 3 with 3 being the minimum and the 3rd lowest being the score used. Also keep in mind we have to do the Marathon too.

What's the earliest deadline for your NFS bunker? We're not doing the first throw so it'd be wasted to release your bunker.

You're putting me to shame, I only have 88 threads

 It's a total of 140 with hyperthreading switched on for those that have it.

 

The 7950x is ripping through the taks. Some of the slower ones are taking over twice as long even single threaded. The slowes is an Intel N100 - but that's running on 10W 

 

Also can confirm - the CPU time went from about 1000s to 1700s (on the 7950X) going from single to hyper-threaded, so overall a good deal.

My 5950x and 2699v3 make up the bulk of my cores, with a few quad core laptops.

 

Although I just got my loqbox savings payout so will be buying a 48 core epyc to replace the Xeon soon

Around a third of them are for the 10th of may. I suppose I could suspend everything else, and just release the ones that are due.

Because you didn't run the benchmark on that host. That's why the points credited are so much lower.
