NVIDIA: 2 threads throw error 'NVIDIA Invalid Result GPU ID n' #2158

Open UselessGuru opened 5 years ago

Problem

XMR-Stak (2.7.1 on Windows 10 17763.195) Miner fails to validate hash at the pool if mining with two threads with NVIDIA

This thread config fails: ThreadsConfig-NVIDIA-CryptonightHeavy-GTX1080Ti-2.txt

Single thread config is fine: ThreadsConfig-NVIDIA-CryptonightHeavy-GTX1080Ti-1.txt

Config file: Config-NVIDIA-CryptonightHeavy-GTX1080Ti-4000.txt

Pool file: Pools-NiceHash-CryptonightHeavy.txt

Command line used: xmr-stak.exe --poolconf Pools-NiceHash-CryptonightHeavy.txt --config Config-NVIDIA-CryptonightHeavy-GTX1080Ti-4000.txt --noCPU --noAMD --nvidia ThreadsConfig-NVIDIA-CryptonightHeavy-GTX1080Ti-2.txt --openCLVendor NVIDIA --noUAC --httpd 4000

AMD (RX 570) is working fine with 2 threads, e.g.: ThreadsConfig-AMD-CryptonightHeavy-Ellesmere4GB-2.txt

Which cuda version du you use?

UselessGuru commented 5 years ago

NVidia driver 417.35 (CUDA 10.0.132)

UselessGuru commented 5 years ago

Any news?

psychocrypt commented 5 years ago

howmuch invalid results do you have. I have no windows with an nvidia gpu so I can not reproduce the issue :(

100%. The miner bails out before mining.

psychocrypt commented 5 years ago

could you please start the miner without nvidia.txt and post all (really all) output from the screen.

UselessGuru commented 5 years ago

post all (really all) output from the screen.

> could you please start the miner without nvidia.txt

I think you are missing the point here because the nvidia config file is the root of the problem :-)

This is the created single thread [nvidia.txt](https://github.com/fireice-uk/xmr-stak/files/2781761/nvidia.txt). This is fine.

It it the double threads on NVIDIA that fail.
Spudz76 commented 5 years ago

I fully understand but do not know why you are trying AMD/OpenCL tricks with CUDA. CUDA most likely does weird things with more than one compute session per card. You might get it to do something in OpenCL mode (--noNVIDIA --openCLVendor NVIDIA) but then config goes in amd.txt and I'm pretty sure that won't work either, or if it does it won't be faster in sum total than the normal single CUDA thread jacked up to max work.

Spudz76 commented 5 years ago

Oh and, if you use --noAMD then other opencl options like --openCLVendor NVIDIA do nothing at all. (your original post command line)

Thank you for this information. The documentation is not very clear on this (at least to me).

UselessGuru commented 5 years ago

I don't understand. I just take the autocreated NVIDIA config and double the threads. Other miners, e.g. XmrigCryptonight perform slightly better with 2 threads.

psychocrypt commented 5 years ago

I will look into it after the next release. There is somewhere a race condition.
