It's nice...  but I couldn't

It's nice...  but I couldn't get for myself even if I wanted one. I have no washer/drier and the stove is gas fired.  The apartment complex I live in won't let me install a 20A 220V circuit.

Get one and use the dryer circuit and use the local laundrymat or use an app where they pick up dirty laundry and drop off your laundry all clean and folded

Mikey,

Some apartments don't include washer/dryer setups in the apartment. They do usually have coin operated lauy facilities.

So that may not be an option for George. This all ignores the budget for 4 rtx 4090's...

yes it does but I thought you were handling that part?

Ran across this on eBay.  It is cheaper than a Titan V. Has a third more theoretical FP performance.

Has less memory bandwidth and a 10 vs 12 GB memory.

So there are a couple of questions here.

  1. Will it play nice with standard Nvidia drivers?
  2. Will the smaller than Titan V memory bandwidth make any difference? It doesn't on my EVGA rtx 3080 ti.
  3. Will a third again faster 32 bit FP be a game changer compared to the Titan V?

Form factor appears to be two slot turbo blower. 

As far as I can understand it, this is a rtx 3080/ti? variant.

#1 is crucial. I have had trouble with other Nvidia mining cards. #3 would make it a serious upgrade to the Titan V.

It is tempting but it could be another trip down the rabbit hole. The Titan V is a proven quantity.

This is just like Tesla, except if has higher clocks. So it would work just fine, if you don't mind the power consumption.

Sure, get it...as it is around ~400€ now on eBAY.

Ok for NVIDIA users who are

Ok for NVIDIA users who are not Power Users ... if you tweak your BIOS and clock rates and 2 or 3 other things to get all the performance possible from your NVIDIA GPU ... you are a Power User.

For the rest of us who would like to get the best that our GPU has NVIDIA is replacing GeForce Experience with a new application called NVIDIA APP.  It's a big improvement over GeForce Experience.  At the moment it is still a BETA level release but on my GTX 1660 SUPER system it runs and is well behaved.  During installation it uninstalled the old GeForce Experience. After installation under System i found a Performance tab which includes an Automatic Tuning option ..... it will do a tuning test playing with system clocks, GPU clocks, Memory and power ......  you should suspend any heavy GPU work before starting the tuning and expect it to take quite awhile. on my system it raised my GPU clock rate 85 Mhz and my VRAM 200 Mhz.

Enjoy

Bill F, While it is

Bill F,

While it is obvious to me it might not be to everyone. This Excellent advice only applies to Windows systems.

We have LOT of Windows users. So if they were not aware I hope they are now.

The MPS server is no longer

The MPS server is no longer showing up with the nvidia-smi command until I start boincmgr.  Then it shows up.  A reason it is concerning is because I apparently forgot to restart MPS yesterday when I was getting things back online after a circuit breaker blew.

So for a significant time it was running without the MPS server.  This slowed the average gpu task's to about 50 minutes per task.

Then when I ran the MPS startup script nothing showed up under "nvidia-smi".

So I assumed the MPS server wasn't running.

Uninstalled the NVIDIA drivers and the ocl drivers on general principles.  rebooted.  reinstalled the "525" drivers by command line so it promptly installed 535 instead....

Then the same failure to display when the gpu tasks were not running under nvidia-smi.

But just now once the boincmgr was running the MPS listings showed up.  Also prior to that when I ran the MPS script the 2nd time it announced the "daemon"? was running.

So right now I THINK the problem is resolved.  But I am irritated/confused by NVIDIA-smi not displaying the MPS server was running.

Hi Tom, Could you share

Hi Tom,

Could you share your multi-GPU MPS script?

I don't know much about this other than just reading about MPS from Nvidia. I couldn't quite understand how it was meant to work with multi-GPU setups. Trying to learn how I can apply it to my own system seeing as there can apparently be a substantial performance uplift.

First I want to thank Ian&SteveC for his help in getting this working!

NOTE!  You cannot run OCL-based processing on this GPU without disabling the MPS server!  It is available ONLY under Linux.  I am using it with with All-Sky GW version 1.14  (the GPU "only" version of the program).

This script was provided to me by Ian&SteveC.  You need to set it "executable" in order to use it.

export CUDA_VISIBLE_DEVICES=0,1,2
export CUDA_MPS_ACTIVE_THREAD_PERCENTAGE=40
export CUDA_MPS_PIPE_DIRECTORY=/tmp/nvidia-mps
export CUDA_MPS_LOG_DIRECTORY=/tmp/nvidia-log
nvidia-cuda-mps-control -d

I call it the same thing Ian&SteveC does (I think):  start_cuda_mps

You need to run it wherever it is located from the terminal using the command line:

sudo ./start_cuda_mps

The "active thread percentage" is apparently a "time slice" for each GPU task.  Both 40 and 70 work for what I am using it for.  But 40% is faster for me.

It will run on Titan V's and rtx 3080 ti's for sure.  And probably anything from the Titan generation on up.

I have to re-boot to disable the MPS server because I am not a Linux expert.

Respectfully,
