RTX 4090 compatibility issue

[Abdul Rahman]

Hello Everyone!

I'm working on training a model with the mgb2_arabic recipe. Once I hit the training dnn step, kaldi spits an error complaining about cuda setup. The error is as follows:

### The CUDA setup is wrong! ("invalid device function" == problem with 'compute capability' in compiled kaldi)
### Before posting the error to forum, please try following:
### 1) update kaldi & cuda-toolkit (& GPU driver),
### 2) re-run 'src/configure',
### 3) re-compile kaldi by 'make clean; make -j depend; make -j'
###
### If the problem persists, please send us your:
### - GPU model name, cuda-toolkit version, driver version (run nvidia-smi), variable $(CUDA_ARCH) from src/kaldi.mk

I've updated all three: kaldi, cuda toolkit, and nvidia driver! The problem still persists...

1. I'm using an nvidia RTX 4090 graphics card, which uses a driver version of 525.
2. The compatible cuda version for that nvidia driver is cuda 12.0, the one I'm using.
3. As for the $(CUDA_ARCH):

CUDA_ARCH = -gencode arch=compute_35,code=sm_35 -gencode arch=compute_50,code=sm_50 -gencode arch=compute_52,code=sm_52 -gencode arch=compute_60,code=sm_60 -gencode arch=compute_61,code=sm_61 -gencode arch=compute_70,code=sm_70 -gencode arch=compute_75,code=sm_75 -gencode arch=compute_80,code=sm_80 -gencode arch=compute_86,code=sm_86

Am I missing something? Let me know if anyone knows anything about this issue! Thanks!

Looks like the compute capability of that one is 8.9 so you have to include an option with sm_89 in it as well
