Create optimized GPU applications in any mainstream GPU
programming language (CUDA, HIP, OpenCL, OpenACC).
What Kernel Tuner does:
- Works as an external tool to benchmark and optimize GPU kernels in isolation
- Can be used directly on existing kernel code without extensive changes
- Can be used with applications in any host programming language
- Blazing fast search space construction
- More than 20 [optimization algorithms](https://kerneltuner.github.io/kernel_tuner/stable/optimization.html) to speedup tuning
- Energy measurements and optimizations [(power capping, clock frequency tuning)](https://arxiv.org/abs/2211.07260)
- ... and much more! For example, [caching](https://kerneltuner.github.io/kernel_tuner/stable/cache_files.html), [output verification](https://kerneltuner.github.io/kernel_tuner/stable/correctness.html), [tuning host and device code](https://kerneltuner.github.io/kernel_tuner/stable/hostcode.html), [user defined metrics](https://kerneltuner.github.io/kernel_tuner/stable/metrics.html), see [the full documentation](https://kerneltuner.github.io/kernel_tuner/stable/index.html).
## Installation
- First, make sure you have your [CUDA](https://kerneltuner.github.io/kernel_tuner/stable/install.html#cuda-and-pycuda), [OpenCL](https://kerneltuner.github.io/kernel_tuner/stable/install.html#opencl-and-pyopencl), or [HIP](https://kerneltuner.github.io/kernel_tuner/stable/install.html#hip-and-pyhipl) compiler installed
- Then type: `pip install kernel_tuner[cuda]`, `pip install kernel_tuner[opencl]`, or `pip install kernel_tuner[hip]`
- or why not all of them: `pip install kernel_tuner[cuda,opencl,hip]`
More information on installation, also for other languages, in the [installation guide](http://kerneltuner.github.io/kernel_tuner/stable/install.html).
## Example
```python
import numpy as np
from kernel_tuner import tune_kernel

__global__ void vector_add(float *c, float *a, float *b, int n) {
int i = blockIdx.x * block_size_x + threadIdx.x;
