Ubuntu 20.04 NVIDIA 2070

Ubuntu 20.04 NVIDIA 2070 Super 460 driver

GPU Used up to 99% GPU memory only 1%

New tasks take forever to finish, aborted the fist one at around 1h45m

Now reading this thread allowed the new one to keep running, 2+ hrs and still going.

I've got a GTX 1660 Ti on a Ryzen 3700X running Ubuntu 18.04 (kernel 5.3) with version 440.10 drivers, and it was failing these - hope that's old enough for a useful data point!

That machine is, of course, on NNT and having an E@H holiday at present (running GW doesn't seem to go well with CPDN and some WCG CPU stuff, so I don't switch over...)

Thanks for that. I didn't necessarily think it would work, but nice to know for sure.

I'm having the same

I'm having the same problems.  My Windows 10 machine with a GTX 1080 is processing the tasks normally.  My other Windows machine with a RTX 2080 usually takes less than 8 minutes but is now unable to finish a single Gamma Ray GPU task.

Hey all, I'm having the same

Hey all, I'm having the same massive slowdown on my FGRP crunching. Ubuntu 20.04 with Nvidia GeForce GTX 1660Ti.  Was originally cruising along at 15 minutes per task, and am now clocking in at 6 hours per task.  GPU is 100% utilized according to the Nvidia control panel, but hardly working (running at 50 degrees celsius, when normally it would be in the 60's). CPU time for the FGRP GPU tasks is incredibly high (like, higher than the equivalent FGRPSSE CPU tasks, which appear to be running fine in parallel with the slow GPU tasks).

Two important notes:

1) My other machine is running a GeForce GT 1030 and is not having the same slowdown problem with the L00 datasets.

2) My 1660Ti machine is running the FGRPopenclTV-nvidia app, while my GT1030 machine is running FGRPopencl1k-nvidia.

I don't see a way to specify which app to use for the FGRP crunching, and I don't know why the 1660Ti machine got all 'TV' apps while the 1030 machine got all '1k' apps.  What is the difference between those apps?

That's all for now.

For information...  The TV app is for cards with chipsets newer than Pascal - TV = Turing and Volta! - and your 1660Ti has a Turing chipset!  So your machines are getting the right applications for their respective GPUs (but these new jobs simply don't work on Turing, Volta and Ampere at present.)

I had restarted my Gtx 1660

I had restarted my Gtx 1660 Super under Windows 10 to see if I would have the same problems.  I do.

Aborted all Nvidia tasks after I had "one" task run 52,000+ wall clock/CPU seconds and then error out.

I have a couple of P106-90 (aka: gtx 1060 3Gb) mining cards that have been munching along under linux.

@alanb1951 that makes perfect

@alanb1951 that makes perfect sense, thanks for explaining that TV = Turing/Volta.  Obscure knowledge I never thought I'd have!

It took us a while to

It took us a while to reproduce the problem. Apparently not all new cards show the same behavior with all new WUs. But we finally found a combination where it occurs. I'm afraid that fixing that will require a lot of debugging.

Thanks for informing us that you are working on it.

 

I wonder why you had "problems" to reproduce the situation.

ALL of my GPU fail with ALL tasks aka WUs.

Have a nice week - stay save !!
