Requirements

• cmake 3.3.0 or higher

  • Debian/Ubuntu: sudo apt-get install cmake file cmake-curses-gui
  • Arch Linux: sudo pacman --sync cmake

• cupla

  • [email protected]:ComputationalRadiationPhysics/cupla.git
  • export CUPLA_ROOT=<cupla_SRC_CODE_DIR>
  • example:
    • mkdir -p $HOME/src
    • git clone [email protected]:ComputationalRadiationPhysics/cupla.git $HOME/src/cupla
    • cd $HOME/src/cupla
    • git submodule init
    • git submodule update
    • export CUPLA_ROOT=$HOME/src/cupla

compile an example

• create build directory mkdir -p buildCuplaExample
• cd buildCuplaExample
• cmake $CUPLA_ROOT/example/CUDASamples/matrixMul -D<ACC_TYPE>=ON
  • list of supported ACC_TYPES
    • ALPAKA_ACC_CPU_B_SEQ_T_OMP2_ENABLE
    • ALPAKA_ACC_CPU_B_SEQ_T_THREADS_ENABLE
    • ALPAKA_ACC_GPU_CUDA_ENABLE
    • ALPAKA_ACC_CPU_B_OMP2_T_SEQ_ENABLE (only allowed in combination with CUPLA_KERNEL_OPTI and CUPLA_KERNEL_ELEM, because the blockSize must be dim3(1,1,1)) see TuningGuide.md
• make -j
• ./matrixMul -wA=320 -wB=320 -hA=320 -hB=320 (parameters must be a multiple of 32!)
