clpeak's Introduction

clpeak

A synthetic benchmarking tool to measure peak capabilities of opencl devices. It only measures the peak metrics that can be achieved using vector operations and does not represent a real-world use case

eg:

Platform: AMD Accelerated Parallel Processing
  Device: Tahiti
    Driver version  : 1445.5 (VM) (Linux x64)
    Compute units   : 32
    Clock frequency : 1000 MHz

    Global memory bandwidth (GBPS)
      float   : 211.27
      float2  : 220.40
      float4  : 217.36
      float8  : 116.76
      float16 : 59.32

    Single-precision compute (GFLOPS)
      float   : 3700.45
      float2  : 3548.87
      float4  : 3531.60
      float8  : 3528.15
      float16 : 3518.72

    Double-precision compute (GFLOPS)
      double   : 864.44
      double2  : 860.07
      double4  : 859.88
      double8  : 850.53
      double16 : 830.28

    Integer compute (GIOPS)
      int   : 783.14
      int2  : 783.54
      int4  : 776.09
      int8  : 753.42
      int16 : 753.52

    Transfer bandwidth (GBPS)
      enqueueWriteBuffer         : 8.86
      enqueueReadBuffer          : 5.29
      enqueueMapBuffer(for read) : 22093.45
        memcpy from mapped ptr   : 3.99
      enqueueUnmap(after write)  : 43471.33
        memcpy to mapped ptr     : 3.92

    Kernel launch latency : 38.14 us
