marcorentap / khpcg3.0

HPCG3.0 updated with Kokkos

Prerequisites

You need:

• Valid install of trilinos with Kokkos and Tpetra packages enabled. (Tpetra requirement will be removed when KokkosCrsMatrix is moved out of Tpetra)
• CMake Version 3.0 or newer
• OpenMP (Not directly used but Kokkos can use this.)

Usage

There are two CMake Keywords:

KHPCG_EXECSPACE={OpenMP, Cuda, Serial (default)} defines the execution space

KHPCG_SYMGS={Color, Inexact, Level (default)} defines the Gause-Seidel implementation (SymGS)

KHPCG_KOKKOS_TEAM={Off, On (default)} defines whether Kokkos Team Policy should be used.

Example use:

mkdir build
cd build
cmake -DKHPCG_EXECSPACE=OpenMP ..
make -j$(nproc)
./KokkosHPCG.exe

The result should be in the HPCG-Benchmark-3.0_*.yaml file
