Since I can't still attach to latinsquares/odlk1, can I get the cliff notes on that thread??

A mathematician can't get ODLK1 to do her work, so she wants to start an ODLK2 project.

Meanwhile the admin promises to upgrade the server in a few months.
 
So next we'll be sprinting on Asteroids. Watch out for boulders and try not to jump too high! 😉
 
Asteroids it is. A gpu project which also runs pretty well on cpu's.😎

I'm still roaming the country, so if someone wants to do stats that would be fine with me. I can post some, but will be spotty at best.😳🙂

That leaves out half my junk, lol. But I thought Asteroids was a CPU project that happens to run okay on GPUs, though? I may have that mixed up.

Yeah, I tend to run it on the green GPUs, but speedwise it's not that much of an improvement

Thanks for the heads up.

Maybe I'll actually attempt at bunkering. Otherwise, I'll switch over now and flush the cache of whatever else.
 
Asteroids on my hardware:

Ryzen 2700x cpu tasks: 1:40 (hours:minutes) average completion time
E5-2690 v2 cpu tasks: 2:40 (hours:minutes) average completion time
GTX1080 cuda tasks: just under 17 minutes
GTX980 cuda tasks: about 20 minutes

Assuming
Ryzen 2700x with 16 tasks at a time and 120 W power use (more than its TDP)
GTX 1080 with 1 task at a time and 150 W power use (less than its TDP)​
gives
Ryzen 2700x ........ 230 tasks per day ..... 110 kPPD ........ 45 kJ per task
GTX 1080 ............... 85 tasks per day ........ 41 kPPD ...... 150 kJ per task​

(Asteroids gives fixed 480 credits/task.)

I hope the sprint won't be like the marathon:

.............................. relative score
Gridcoin ............................... 100
Czech National Team ............ 10 *
TeAm AnandTech ..................... 1​

*) it's Asteroids' home team
 
As long as the current financial crisis holds and vast sums of surplus money are being pumped into crypto coins (including GRC), I expect that servers running out of work at the beginning of Formula BOINC sprints will remain the norm.

The other problem is that project admins are not being notified by Sébastien.

Edit,
czech, french, and german forum posts indicate that the server ran out of work 8 hours ago, if not earlier.

The project announcement was at 00:00 in my local time. Yesterday I asked myself whether I should stay up late for the announcement, or go to sleep at a sane time and look the sprint project up in the morning after. I will keep in mind for the next sprints that one of these methods lets me fetch work, and the other generally doesn't.

Edit 2,
there is another particular of Asteroids@home to keep in mid: The project runs out of tasks repeatedly, outside competitions. Therefore, long-term contributors were advised to run Asteroids with a deep work buffer. If many people followed this advise, very long times until validation of reported tasks will be the consequence.

Limited server disk space was stated as the usual reason why Asteroids runs out of work ready to send periodically. — Sadly, telling people to configure deep work buffers only aggravates this problem.

Power usage from the wall readings on the 2700x@3.8 GHz. CPU voltage is 1.125 with CPB (core performance boost) disabled.​

IDLE: 52 watts
Full load on Asteroids: 200 watts

Heh, I didn't think anybody had actually started asteroid mining yet! 😛

You've got my ryzen beat by a long shot!
Click to expand...
Yeah, as much as I like my Ryzens, they disappoint on AVX projects, or is it AVX2? A comprehensive list of which projects utilize which instructions would help to make purchasing decisions. It may be that Haswell/Broadwell are providing the best price/performance ratio for this type of project.
 
The sse2, sse3, and avx application builds are close to each other in performance. However, at least the avx version (don't know about the others) do have an instruction mix which triggers the AVX clock offset of Broadwell-EP (and according to your post, of Coffee Lake).
 
My 2680v2 @ 3.1GHz is finishing WUs in ~2:57, HT ON. So there is something going on where Haswell and up is much better at these then Ivy or below, and much better than Ryzen, too.

It turns out your 8700K can do 288 tasks per day and my ryzen does 230 per day. The extra 4 threads on the ryzen helps a little.

That's true, and Ryzen represents a tremendous value! The part that bothers me is that it's not very straightforward to compare Ryzen to Intel, and I do that often when deciding how to upgrade. Per dollar, Ryzen looks okay on this project even with the large per-core deficit, bur per watt/hour? Probably not so much here.
