+## Kokkos
+
+* Kokkos implementation requires kokkos source folder to be provided because it builds it from the scratch
+
+
+| Flag        | Definition                      | 
+|-----------| ----------------------------------|
+| dir | Download the kokkos release from github repository ( https://github.com/kokkos/kokkos ) and extract the zip file to a directory you want and target this directory with `dir` flag |
+| backend     | 2 different backend options: <br />- cuda <br />- omp | 
+| cuda_arch     |- List of supported compute capabilities are provided [here](https://github.com/spack/spack/blob/0f271883831bec6da3fc64c92eb1805c39a9f09a/lib/spack/spack/build_systems/cuda.py#LL19C1-L47C6) <br />- Useful [link](https://arnon.dk/matching-sm-architectures-arch-and-gencode-for-various-nvidia-cards/) for matching CUDA gencodes with NVIDIA architectures|
