nvcc fatal : Unsupported gpu architecture 'compute_30'

[zehrealmrmeow]

I have checked out the latest revision and when I try make I get the following error:

$ make
[ 1%] Building NVCC (Device) object CMakeFiles/xmrig-cuda.dir/src/nvidia/xmrig-cuda_generated_cuda_extra.cu.o

My NVIDIA driver is:
$ nvidia-smi -l

| NVIDIA-SMI 510.39.01 Driver Version: 510.39.01 CUDA Version: 11.6 |

My NVIDIA card is:
$ lshw
*-display

vendor: NVIDIA Corporation
physical id: 0
bus info: pci@0000:07:00.0

After googling it out I was able to find (not many) similar posts yet the one that came the closest to this problem was: flashlight/flashlight#198

I have of course tried to inspire myself off this article but to no avail. I understand that I would need to add "-gencode arch=compute_30,code=sm_30" somewhere under CMakeLists.txt, possibly in:
option(WITH_AEON "CryptoNight-Lite support" ON)
option(WITH_SUMO "CryptoNight-Heavy support" ON)
option(WITH_CN_PICO "CryptoNight-Pico support" ON)
option(WITH_CN_GPU "CryptoNight-GPU support" ON)
option(WITH_HTTPD "HTTP REST API" ON)
option(WITH_DEBUG_LOG "Enable debug log output" OFF)
option(WITH_TLS "Enable OpenSSL support" ON)
option(WITH_ASM "Enable ASM PoW implementations" ON)
option(BUILD_STATIC "Build static binary" OFF)
option(ARM_TARGET "Force use specific ARM target 8 or 7" 0)

But at this point I am beyond my head.

Can anybody help me out getting xmrig-nvidia running on my system? And/or will future revisions support/fix what I am trying to accomplish?

cmake .. -DCUDA_ARCH="35" -DWITH_HTTPD=OFF -DWITH_AEON=OFF should get you around it, I had a similar issue.

That properly fixed it! THANK YOU <3

However I am never able to start the PID:
$ ./xmrig-nvidia --donate-level 5 -o poolip:poolport -u myusername -p x -k
[2022-02-17 15:32:17] "cryptonight" hash self-test failed.
$

After duckducking it out the closest match that I was about to find was this but it ended up as a bug fix in 2018 for xmrig: xmrig/xmrig-amd#131

If you absolutely must do this, here's how.

• Pull the repo as per normal.
• Remove these lines from src/App.cpp
  • https://github.com/xmrig/xmrig-nvidia/blob/master/src/App.cpp#L95-L98
• Run the following commands to build the miner and start running.

sudo apt-get install git build-essential cmake libuv1-dev libmicrohttpd-dev
git clone https://github.com/xmrig/xmrig-nvidia.git
cd xmrig-nvidia
mkdir build
cd build
cmake .. -DCUDA_ARCH="35" -DWITH_HTTPD=OFF -DWITH_AEON=OFF
make

./xmrig-nvidia -o randomxmonero.eu-west.nicehash.com:3380 -u 3MzMtMvTWUXtNS4WmKcUoRbPmfJKHuRXTM.ifyoudothisyouaresilly -p x -k --nicehash

While it does work, and you can get even very old GPUs mining, it's absolutely NOT worth it.

For reference, I tried mining with a passively cooled Nvidia GT 710. The GPU pulled around 5w in exchange for a consistent 19.5 H/s. Note hashes per second, not kH/s. It'd make about a cent a month in revenue. There's also the side-effect of the CPU overhead, near enough maxing out a single thread constantly thus further pushing up the total power draw into the 10-15w range. Though it's far more likely that your terrible hashrate will mean your jobs are so old by the time you've finished with them you'll get rejected every single time.

Just for clarity on how bad GPU mining Monero is, you'd need a thousand GT 710s to have a $10/month revenue. Plus an electricity bill somewhere in the $2,000/month range.

Have fun!

P.S: If you're not just screwing around, what you actually want is here https://github.com/xmrig/xmrig-cuda

This project has been abandoned after the fork to xmrig-cuda plugin for normal xmrig

You will all have much better luck using actually supported software. This is dead since 2019.
