With Nvidia cards you have the ability to run Linux and the special app which is going to trump the production of any ATI card irregardless of OS.

The TR platform is always going to come out ahead because of the ability to support more gpus than the AM4 platform, even with the R9-3950X matching cpu core and thread count of the TR cpus.

The TR memory subsystem as a four channel setup totally kills the AM4 2 channel memory benchmarks even at stock 2666Mhz memory and the AM4 memories running at 3466 or greater.

The AMD Ryzens look to be giving Intel a good run for whatever money:


AMD Ryzen 7 3800X Glides Past Intel Core i9-9900K In Leaked Geekbench Numbers

Geekbench 4 results for AMD's soon-to-be-released Ryzen 7 3800X processor have been unearthed, giving us some performance numbers to to compare against the Intel Core i9-9900K...

... Both the Ryzen 7 3800X and i9-9900K are octa-core processors with 16 threads, making them natural rivals. However, that's where the similarities end...




DigiTimes: Intel to Slash Desktop Processor Pricing up to 15 Percent as Ryzen 3000 Nears

DigiTimes reported today, citing sources at motherboard makers, that Intel plans to cut the pricing of its eighth- and ninth-gen processors by 10-15%...

... All this means Intel will have to become more competitive in at least some fashion...




All at long long last! And at long last all for the common good.

But why have we had so many years of stagnation until just now?...

Great to hear Shannon. I will be watching the host's progress. It looks like you are primarily doing gpu only. Are you putting the cpu to work on other projects?

Maybe it will take a while?

I looked further and found some. There is a shortie storm currently and the cpu tasks are overflowing instantly along with the gpu tasks. Had to flip through several pages to find some of your cpu tasks. Since you are running the stock cpu app, I can't tell what speed the cpu is clocking. Taking around 3 and half hours for the cpu tasks. Not great but expected for the stock cpu application. Doesn't look like you are overloading the cpu that much. Run_time is only 15 minutes longer than cpu_time.

I wonder if it’s going to take a while for this machine to settle in because my 2700x can do work units on the cpu in about an hour and a half.

It could also be where I brought my drives over into the new computer from the old and those cpu times are what my old computer was doing... around 4 hours on cpu wu’s on the Xeons.

I may do a clean format and reinstall of windows and Boinc tomorrow.

If those cpu tasks were started on the Xeons, then finished on the Threadripper, no concerns. You need to track a cpu task started and finished on the 'ripper. If the TR isn't overloaded with too much work, then the tasks should finish in about the same time as on the Ryzen. We with TR's have figured out that 50-60% cpu loading on the TR will produce the shortest crunching time, but it may not produce the maximum tasks finished per day. If that is your goal then you might want to increase your max cpu concurrent loading. Again, it will take months for RAC to stabilize. If the cpu is to be the max producer then you will want to run more cpu tasks. If the gpu is the intended max producer, then reduce the cpu loading.

How do you have your TR setup? Short crunching time or max tasks per day? I have one core for the gpu and the others are running cpu tasks.

I have mostly gpus so the cpu is just nice to add a little to the output of the gpus. Take a look at how many cpu tasks you return per day at full 100% utilization with the long crunch times versus the shorter crunch times of only running at 75% utilization. It it takes 4 hours per task at 100% usage versus 2 hours per task at 75% usage, your turnout per day is actually higher at lower utilization.

I really need to get a couple more 1060's later on don't I? I mean I'm ok with whatever the machine is cranking out right now with 1 GPU and the rest CPU since everything we do matters.

I wonder if my GTX 1060 6gb could do 2 tasks at one time... would I feed it with 2 CPU cores if I try.

I swear this stuff is more complicated than I ever thought LOL!!!!

You have to see how much Memory you have on 1060. 6 GB version, You could probably run 2 SoG at a time but nothing more. The 3 GB version is limited to 1 SoG.

Would I use 2 cpu cores to feed it or leave it at one?

Modify either the app_info or app_config to allow 2 units per GPU and 1 core for each work unit. So 2 cores for 2 work units per card.

Here's what I used... unfortunalty the issues weve been having with work unit noise is happening to me too. Some wu are only 10-15 secs worth of junk.

Showing 2 CPU's + 2 NVIDIA GPU's now and hwmonitor says 100% GPU Utilization and 42% Memory usage and 52c temp

I've modified your app_config so 2 work units per gpu and 1 thread for each work unit. I've also freed up a thread to help feed the GPU and reduced the number
of CPU tasks to allow for this. Place this in the seti@home fold and used the pull downpull from options to reread the configs.

I would suggest reading all of this thread from the beginning starting with jsm's OP. He has a 2990WX and has spent several months trying to find the optimal cpu task usage loading that produces the greatest amount of RAC with the fastest possible cpu times. Just a hint though . . . . it was NOT with all cpu cores crunching cpu tasks. Meat of the matter on Page 4.
