There are several build options for Katago's derivation. Katago can use either Eigen, OpenCL, CUDA, or TensorRT. By default, it uses OpenCL. To use a different backend override the `backend` attribute, allowed values are "eigen", "opencl", "cuda", and "tensorrt".

For the eigen and cuda backends either version should be more or less functionally the same.

===Using CUDA===

katago.override {

~~enableCuda~~ = ~~true~~;

backend = "cuda";

cudnn = cudnn_cudatoolkit_10_2; # insert your favorite version of CUDA here

cudnn = cudnn_cudatoolkit_10_2; # insert your favorite version of CUDA here (optional)

cudatoolkit = cudatoolkit_10_2; # I recommend at least CUDA 10, because older versions suffer major performance penalties

stdev = gcc8Stdev; # If you specify CUDA 10 or below you must also override the gcc version, this is due to NVidia compiler support.

}

===Using Eigen===

katago.override {

backend = "eigen";

}

Using ~~Eigen~~:

===Using TensorRT===

First download the tensorrt redistributable installer from https://developer.nvidia.com/tensorrt and add it to your nix-store.

Note that you need an NVidia account (free) to do this.

katago.override {

~~enableGPU~~ = ~~false~~;

backend = "tensorrt";

enableTrtPlanCache = true; # Recommended to speed up booting, but uses additional disk space, so not recommended for contrib.

}

==Configuration==

If your processor support AVX2, you might want to enable it:
