Megpack is a tool for testing processor peak computation, now support arm, x86 and GPU driven by OpenCL processor.

MegPeak can do:

• Peak bandwidth of instruction
• Instruction delay
• Memory peak bandwidth
• Peak bandwidth of arbitrary instruction combination

Although some of the above information can be obtained by querying the data sheet of the chip, and with guidance the theoretical the peak performance can be computed, but in many cases, the detail performance documents of the target processor cannot be obtained. In addition, the result through megpeak is more direct and accurate, and it can test the peak bandwidth of arbitrary instruction combination

MegPeak only support Cmake build system and require Cmake version upper than 3.15.2, you can compiler the MegPeak fellow the step:

• clone or download the project
• choose a test plantform
  • if you will test x86 processor in linux OS
    • a gcc or clang compier should find by camke through PATH env
  • if you will test arm processor in android OS
    • a ndk is required
      • download the NDK and extract to the host machine
      • set the NDK_ROOT env to the path of extracted NDK director
• if you dest test OS is android，run the android_build.sh to build it
  • build for armv7

    ./android_build.sh -m armeabi-v7a

  • build for arm64

    ./android_build.sh -m arm64-v8a

  • build with OpenCL

    ./android_build.sh -l -m [arm64-v8a, armeabi-v7a]

• if you dest test OS is linux，if you want enable OpenCL add -DMEGPEAK_ENABLE_OPENCL=ON to cmake command

  mkdir -p build && cd build
  cmake .. [-DMEGPEAK_ENABLE_OPENCL=ON]
  make

• after build, the executable file megpeak is stored in build drector

if you compiler the project and get the megpeak, next you can copy or set the megpeak exectuable file to the test machine，and run it and get the help message. bash ./megpeak -h

• test opencl

  ./megpeak -d opencl

• test CPU with cpu id

  ./megpeak -d cpu -i 0
