# ROOT GPU Optimization Experiments for High Energy Physics Analysis
## Dependencies and Compilers
| Package | Version | Notes |
|---------------------------------------|----------------------------------------------------------------------------------------------------------|-------------------|
| ROOT | 6.33.01 ([5b7b6cc0](https://github.com/root-project/root/tree/5b7b6cc0253a145ee59b8890b6e26d81ac7198b4)) | Build from source |
| Google Test | 1.15.2 ([b514bdc8](https://github.com/google/googletest/tree/b514bdc898e2951020cbdca1304b75f5950d1f59)) | Build from source |
| GNU Compiler Collection (`gcc`/`g++`) | 12.3.0 | |
| CUDA Toolkit (includes `nvcc`) | 12.5 | |
## Performance Results
The following results are obtained on a machine with an `AMD Ryzen 7 5700g`
processor and `NVIDIA GeForce RTX 3060` GPU, by running the
`./runBenchmarks.sh` script in the root directory.
Note that some runtimes might not add up to the total time reported. This is
due to the intermediate times being rounded.
