p2z-tests

OpenMP

Compilers: gcc, icc, pgi.

version 3 is most up to date. $ make COMPILER=gcc MODE=omp $ make COMPILER=icc MODE=omp $ make COMPILER=pgi MODE=omp

OpenACC

Compile with PGI

//Compile OpenACC C++ version $ make COMPILER=pgi MODE=acc SRCTYPE=cpp //Compile OpenACC C version $ make COMPILER=pgi MODE=acc SRCTYPE=c

Tbb

Compilers: gcc, icc

$ make COMPILER=gcc MODE=tbb $ make COMPILER=icc MODE=tbb

CUDA

Compilers: nvcc

Version 1 uses unified memory. Version 2 uses explicit memory transfers $ make COMPILER=nvcc MODE=cuda

Eigen

Compilers: gcc, icc, nvcc

$ make COMPILER=gcc MODE=eigen $ make COMPILER=icc MODE=eigen $ make COMPILER=nvcc MODE=eigen

Alpaka

Compilers: gcc, nvcc

$ make COMPILER=gcc MODE=alpaka $ make COMPILER=nvcc MODE=alpaka//not yet functional

Compile with OpenARC

1. set the environment variable, openarc to the root directory of the OpenARC repository.
2. $ O2GBuild.script
3. $ make COMPILER=openarc MODE=acc SRCTYPE=c

OpenARC in the public repository has bugs in handling async versions.

Therefore, do not use propagate-*_async.c files as input.

Kokkos

The kokkos version exists in its own directory, src/kokkos_src, which contains the p2z code along with a Makefile and README to help the user make use of the Kokkos library. Here we have basic instructions.

Getting started

1. clone https://github.com/kokkos/kokkos to ${HOME}/kokkos
2. in the src/kokkos_src direcory edit the Makefile setting to match your needs
3. run make to build
4. The executable can be found under bin with the others

Makefile setting

• KOKKOS_DEVICES = OpenMP or OpenMP,Cuda
• KOKKOS_ARCH = [GPU arch],[CPU arch] i.e. "BDW,Volta70"
