Kokkos Model

[pranav-sivaraman]

We have created a Kokkos Implementation of XSBench

cc: @jhdavis8

Notes

Makefile Build Type

• Allows users to build Kokkos from scratch and assumes that the Kokkos repository is located in the same directory as the Kokkos model.
• Simplifies the process of getting started with XSBench and Kokkos

CMake Build System

• Allows linking of XSBench with an installed Kokkos Package
• Can't link to an installed Kokkos installation with Makefile.

Kokkos Execution Policies

• Kokkos allows the user to build multiple execution policies for both Host and GPU environments
• Kokkos follows a hierarchical priority. The order is device, host-parallel, and serial execution modes.
• If you want to use the only OpenMP backend you have to configure and build Kokkos only with the OpenMP backend

Any feedback would be greatly appreciated
