MegPeak

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

MegPeak can do

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

BUILD

MegPeak only support CMake build system and require CMake version upper than 3.15.2, you can compile the MegPeak follow the step:

  • clone or download the project
  • choose a test platform
    • if you will test x86 processor in linux OS
      • a gcc or clang compiler should find by cmake 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 directory
  • if your target 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]
    • build with all benchmark 
      ./android_build.sh -a -m [arm64-v8a, armeabi-v7a]
  • if you target test OS is linux，if you want to 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 directory

Run

If you compile the project and get the megpeak, next you can copy or set the megpeak executable 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
