Kokkos

Kokkos

Kokkos Core implements a programming model in C++ for writing performance portable applications targeting all major HPC platforms. For that purpose it provides abstractions for both parallel execution of code and data management. Kokkos is designed to target complex node architectures with N-level memory hierarchies and multiple types of execution resources. It currently can use Serial and OpenMP (threads) for CPU execution spaces ("backends") and CUDA, HIP, SYCL, and OpenMPTarget for GPU execution spaces. By convention, Kokkos only allows one GPU backend at a time.

Kokkos on Polaris

The prebuilt Kokkos on polaris includes 3 backends: Serial and OpenMP for CPU execution and CUDA for GPU execution. To use it, run

module use /soft/modulefiles
module load kokkos
