Kokkos
Modern high-performance computing (HPC) architectures have diverse and heterogeneous types of execution and memory resources. For applications and domain-specific libraries/languages to scale, port, and perform well on these architectures, their algorithms must be re-engineered for thread scalability and performance portability. The Kokkos programming system enables HPC applications and domain libraries to be implemented only once, while being performance portable across diverse architectures such as multicore CPUs, GPUs, and APUs.
This research, development, and deployment project advances the Kokkos programming system with new intra-node parallel algorithm abstractions, implements these abstractions in the Kokkos library, and supports applications’ and domain libraries’ effective use of Kokkos through consulting and tutorials. Kokkos is an open-source project in the Linux Foundation, with the primary development support coming from Sandia National Laboratories, Oak Ridge National Laboratory, and the French Alternative Energies and Atomic Energy Commission.
