cupla Install Guide

Requirements

  • cmake 3.7.0 or higher

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

  • cupla

    • https://github.com/ComputationalRadiationPhysics/cupla
    • export CUPLA_ROOT=<cupla_SRC_CODE_DIR>
    • example:
      • mkdir -p $HOME/src
      • git clone git://github.com/ComputationalRadiationPhysics/cupla.git $HOME/src/cupla
      • cd $HOME/src/cupla
      • git submodule init
      • git submodule update
      • export CUPLA_ROOT=$HOME/src/cupla
    • use cupla without the submodule alpaka: Set the advanced CMake variable cupla_ALPAKA_PROVIDER to extern and set environment variable ALPAKA_ROOT or extend CMAKE_PREFIX_PATH with the path to alpaka.

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_CPU_B_TBB_T_SEQ_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!)
