I managed to fix it in January and it all dumped at once to the tune of 3,147,057 credit. Wish I would have held on to it for another 4 months! Such is the price of not knowing what you're doing with most of this stuff :-D

Anyway, hooray Einstein! My favorite.
You allowed stats export. The Pent pulls team stats which is irrelevant if individual users allow export or not.

Someone must be hogging up all the nvidia tasks. My 2 1070tis have been sitting mostly idle, only getting a single task at random intervals. I still have plenty of AMD tasks.

I have plenty now, but scrolling through the logs I can see periods when I didn't on my faster cards.


No tasks to send and workload generation seems to be off for FGRPB1G https://einsteinathome.org/server_status.php at the moment.

Probably has more to do with this gen of Radeon GPUs mostly being poor sellers after mining craze (RX 470/RX 570/ RX 480 / RX 580 / Vega 56) vs the Nvidia counterparts (RTX series, GTX 1070, GTX 1080 + 1080 Ti) , combined with the typically lower efficiency of Radeon on Einstein in general except for the double precision portion. The 7nm Radeon is too new and expensive with no aftermarket cards even if the FP64 is higher and the amount sold is obviously less.

The notation on double precision can be found here: https://einsteinathome.org/content/u...ement-einstein

Granted VRAM is lower on the low end Nvidia GPUs such as the GTX 1060 3GB and GTX 1050 3GB/2GB not to mention the GTX 970 fiasco with "3.5GB" , but the bulk of Nvidia GPUs are 6GB+ these days (everything from Turing GTX 1660 and up). Turing is able to do concurrent int + float operations.

AFAIK you need only about 1.5GB of VRAM unless you're running more than 2 tasks concurrently.

Over at SETI there is a thread on the GTX 1660 (presumably the non-Ti GDDR5 version) and this is the result:
Quote:
GTX 970 - 6.4 minutes/task
GTX 1060 - 7.3 minutes/task
GTX 1660 - 4.5 minutes/task
https://setiathome.berkeley.edu/foru...tyle=&start=20

This year gridcoin team isn't present so that's good. I don't remember the Scottish team though?

Edit: see also https://setiathome.berkeley.edu/foru...yle=&start=220
GTX 1660 TI seems to be impressive perf/watt per post https://setiathome.berkeley.edu/forum_thread.php?id=81962&postid=1988037 and https://www.phoronix.com/scan.php?pa...i-opencl&num=3

All my cards, NVIDIA and AMD are seeing no work units available messages now. I have about an hour queued up on my faster systems.


@AlphaC not sure what you are trying to say. My RX-470 is faster in Einstein then my GTX-1070 and GTX-980ti, and I doubt it's using more energy than either.



The Scottish team looks like a temporary amalgamation of teams formed to build a super team and dominate the competition. Look at SUSA in the stats, a number of people from there changed teams for the event, and now instead of on top they are well down the stats.

I'm just saying general OpenCL performance isn't as high as it could be , Einstein may be an outlier given that the OpenCL benches and [email protected] performance don't reflect that

If you look at the RX 590 position on "OpenCL Test: Global Memory Bandwidth" that's the only time it really matches Pascal besides single precision float. Granted Einstein uses memory bandwidth more.


edit: I looked at Einstein's database of top computers and some RX 570s are getting 1200s , RX 580s around 1000s, Vega around 600s. GTX 1080 ran around 500s-700s, GTX 1080 TI around 450s. No note about the concurrent WUs.

Work generators do not run all the time as there is no need usually. But now there are no FGRPB1G tasks available atm.

A proper SETI setup should be CUDA in Linux. The optimized Windows app is much slower. No comparison to [email protected] at all.

Those 570s and 580s running at 1k-1.2k are 2x tasks. Vega is probably 2x as well at 600s. A 570 is just as fast as a 580 in [email protected] Its all about memory speed. A card with a Mining BIOS gains a nice boost. I saw no change going from 1430 to 1366 core clock. But OCing the memory does wonders.

My own at 1x
GTX 1070: 12:42
GTX 1070Ti: 11:22
GTX 1080Ti: 7:29
RX 580: 10:14

Well, that theory makes sense. My Fury X takes roughly 6:30 to complete single tasks, and 11:00 to do 2x tasks. It does have more memory bandwidth than the Vega 56/64.

http://wuprop.boinc-af.org/results/g...rojet&sort=asc

Also, while i don't have a bunker built, i still have like 100+ tasks queued up. Should be fine for at least half a day on that.

My 1070 at 2x tasks at a time (1CPU + 0.5Nvidia GPU, two at a time) is taking ~43 minutes per Gamma-ray pulsar binary search #1. Is that as expected?

Seems slow. I am running two tasks on a 1070 and averaging about 1640 seconds per task, so 27:33. Win 10 Pro, NVIDIA 388.13. I have nothing but BOINC running on that system at this time, so those tasks are getting two full threads.
