Everyone helped me a couple months ago get my ASUS Expedition GTX 1060 6gb tuned and running great on my main crunching rig (Dell T7400 Dual Xeon 5450 8 Cores). With everyone's help we had the gpu doing tasks in about 7 minutes. Well.... it has gotten slower and slower, I was seeing 7 minutes, then 8 something, 9 and now today work units are completing around 10:32 so something is up.

I am still running the command line given to me:

-sbs 1024 -period_iterations_num 1 -tt 1500 -high_perf -high_prec_timer -spike_fft_thresh 4096 -tune 1 64 1 4 -oclfft_tune_gr 256 -oclfft_tune_lr 16 -oclfft_tune_wg 256 -oclfft_tune_ls 512 -oclfft_tune_bn 64 -oclfft_tune_cw 64 -hp

and 1 CPU + 1 NVIDIA GPU in app_config.xml, computing preferences are:

Use at most 100 % of the CPUs
Use at most 100 % of CPU time

I'm stumped as to why this is happening...

Also I really need to get my other machine to running better with the help from my VEGA thread but I have been so busy with work that I haven't had time to work on it and I've just left the main cruncher to its own.

How many work units are you running and how many are on the GPU?

---

1 work unit at a time on the gpu and 7 on the remaining cpu cores.

It's just the variation in the workunits available and nothing wrong at your end, if fact my 3750K rig (Win7) has recorded its lowest RAC ever under just Green Bank work.

Cheers.

To add to Gary's post it is well know Nvidea GPUs don't really do well on VLARs which is what Green Banks data is. IIRC at on time the project wouldn't even send them to Nvideas.

Reduce your CPU use to 5 CPU jobs. You may be starving out the CPU resources available to properly feed the GPU.

Seti@Home classic workunits: 29,492 CPU time: 134,419 hours

On my GPU the tasks take ~250 seconds or ~310 seconds, depending on blc2n, at the moment blc25 are taking 310s and blc26 250s.

You are currently crunching through the re-introduced BLC25 data. That is some of the hardest and longest running BLC data we have seen in a year. Nothing wrong with your setup. The RAC is just going to fall when Green Bank data is all we get. Accept it.

Dang that’s rough! Well I’m glad that there’s nothing wrong because I’ve been racking my brain trying to figure out if something had happened that I wasn’t aware of. I’m still learning too so thanks sir! :)

Thanks all for posting about this. I was in the same boat racking my brain trying to figure out what I could have unwittingly messed up to make my RAC steadily decrease like this.
