You can use the latest version of Kokkos. The experiments of the paper "Multi-threaded Sparse Matrix-Matrix Multiplication for Many-Core and GPU Architectures" uses kokkos-version: 2.04.04

Currently KokkosKernels-spgemm updates are not on the master branch yet (12/20/2017). Checkout the develop branch.

Below is the example of compileKokkosKernels.sh for Power8 with OpenMP execution space.

Set the compiler. If you use mkl, export the mkl path.
module load intel/compilers/18.0.128
export MKL_PATH=/home/projects/x86-64-knl/intel/beta/pstudio/2018-B1/compilers_and_libraries_2018.0.061/linux/mkl/
cd $HOME/kokkoskernels_spgemm_benchmark/kokkos-kernels/example/buildlib
./compileKokkosKernels.sh
make build-test -j
Below we show how to run benchmarks using KNL-CACHE mode.
- Allocate the node using appropriate scheduling command.
- Download a UFL sparse matrix. We are showing it on audikw_1 in this example.
- Each is run 6 times, which can be changed using "repeat" keyword ("repeat 15" to repeat 15 times.)
- First run is always discarded as warm-up. For each algorithm below, we run from 64 to 256 threads.
- I am using ".bin" files below for faster I/O handles. ".mtx" files can also be used, based on the suffix correct reader will be called. But for faster experimenting, you can use KokkosKernels_MatrixConverter.exe as below for converint mtx files to bin files.
./KokkosKernels_MatrixConverter.exe in_mtx audikw_1.mtx out_mtx audikw_1.bin
- Set the environment variables, go to the executables folder.

To fit to the use of SpGEMM in Trilinos, mkl-inspector is called twice for both in symbolic and numeric phases and there are some post-processing. To benchmark its runtime, we exclude all these post-processing by providing the "verbose mklkeepout 0" to executable. The timings that we take into account is "Actual DOUBLE MKL SPMM Time Without Free", rather then previous mm_time, symbolic_time and numeric time. Note that first call is much more expensive than the rest, which we exclude.

There are some pre-and post processing because of the methods working on 1-base. The symbolic time is printed at "Actual MKL2 Symbolic Time" and numeric time is printed "Actual MKL2 Numeric Time", which are the times surrounding mkl spgemm calls.
