Yea, I'm still sure it's slower than baremetal as I don't really know all the secrets to get the maximum performance for this situation, but it's this or not being able to use the hardware at all and something is better than nothing lol

We can't complain about how you setup the servers when you have almost (if not more than) 500 physical cores to offer. That's probably more than what the rest of the team has combined. 500 extra cores period will make a significant point difference.

Right now I have 4.7% of the running tasks in SiDock@Home, I'll set myself an overly ambitious goal of hitting 10%, but only before the event it'll drop heaps during.

Nice, very nice. All worth using if you can, up to you how much you want to contribute.

 

Rather inefficient, but I'm happy to use it all for the event. My 3700x and e5-2680v2 will be dedicated to running boinc, but some of the others will have to perform other tasks from time to time.

 

To what extent does boinc perform better on higher thread count cpu's over faster single core performance cpu's with fewer threads? 

 

I have seen similar multicore performance between my 1600af and e5 2680v2 in many applications, will this translate to boinc or will the e5 pull away with its 8 extra threads?

More threads/cores tend to be better as you can run more tasks, higher clocked cores will finish the tasks sooner but not so much sooner as it generally makes up for by having fewer cores. Where the real difference comes in is if one archecture/generation is actually 40%+ IPC higher performance then fewer of these faster cores will do better.

Not sure to be honest, the E5v2 stuff is rather slow compared to more modern stuff so it'll likely be a rather fair fight between them actually. A lot of what I'm running is also E5v1/v2 and even some older 5600 series too. I have newer E5v3 and E7v4 systems but less of those.

You reminded me that I still needed to register. :old-tongue:

 

This year I'm working with 110 cores, 220 threads I don't know what percentage of the overall tasks I'll have but I hope I put them to good use.

Great info thanks.

 

I have a new 360 rad on my 3700x, so I will get to overclocking it 🙂.

 

I remember boinc being quite the memory hog, how much ram per thread do you recommend?

 

Presumably you lose performance if the cpu is doing a lot of read/writing to the paging file?

It actually depends on the project, SiDock uses hardly any so I doubt you'll have any problems. 4.6GB on 12c/24t system and 17GB on 96c/96t system.

 

As we find out what the other 4 events/projects are how much ram you'll need will change, but you can run low memory tasks with high memory tasks at the same time to fill out the threads if you have to.

That's still a lot and here's to hoping that those 220 threads running on the real thing will get you pretty damn close to what I have running.

I don't think hypervisor overhead is going to cut you down to 20% the output. I'm working with mostly Xeons & an EPYC so I won't be anywhere near your output.

With WCG/OPN it's about the same as my dual Xeon E5-2698v3 rig. Plus or minus a few. We will see if a particular workload takes advantage of anything special in the CPU I'm not aware of. 😉

Oh almost forgot, SiDock@Home does not have checking pointing so DO NOT pause running tasks as you'll lose any current processing done.

You should probably put that on the first post itself, 'cause many people are unlikely to read through the entire thread and this would be useful for newbies.

I think the old 3930K needs a little TLC:

245139000_Screenshotfrom2021-04-2917-04-37.png.9accc8cf101fb32065879ba18390dac1.png

It's only running a 4.1GHz O.C. but she's air cooled and I haven't touch the server since...uh...

boinc@boinc-node-7:~$ uptime
21:07:27 up 103 days,  3:05,  1 user,  load average: 10.00, 10.00, 10.00

Usually runs at 4.5, 4.6 was stable for the last couple days, now testing 4.7. It used to do 4.9 at a hot push but running it hard has degraded the chip by a fair margin over the years. Think if I had better cooling for it it maybe could do 4.8, possibly 4.9 again. If this is stable going to try having 50% of the cores at 4.8. Every clock cycle counts for the pent!

It used to be on a custom look with two thicc rads

It's times like this I wish the Xeon/Server market as a whole supported overclocking. I'd love to push my 16 cores & 32 core processor farther for the Pent but it is what it is.

 

I can look into OCing the 1950X. It's basically a cut down 7001 EPYC CPU.

 

Question is can I keep the heat in check? 👀
