5.2. Running Vector Add

  1. Extract example:
    cd $OPAE_PLATFORM_ROOT/opencl
    
    mkdir exm_opencl_vector_add_x64_linux
    
    cd exm_opencl_vector_add_x64_linux
    
    tar xzvf ../exm_opencl_vector_add_x64_linux.tgz
    
  2. Build example:
    cd vector_add
    
    make
    
  3. Copy precompiled OpenCL* kernel to bin folder:
    cp $OPAE_PLATFORM_ROOT/opencl/vector_add.aocx ./bin
  4. Program the aocx file:
    aocl program acl0 ./bin/vector_add.aocx
    Note: This step is not necessary for non SR-IOV enabled system as OpenCL* by default performs partial reconfiguration to program the new kernel on FPGA. The aocx file in the release OpenCL* folder is unsigned. If you are using Intel® FPGA PAC features and programming a signed aocx file to the device, ensure that you copy the same file in the bin before running. Also, make sure that you rename the file to vector_add.aocx because the hose code looks for the specific name of the kernel.
    Example sample output:
    Running program from /home/<username>/intelrtestack/d5005_ias_2_0_1_b237/opencl/opencl_bsp/linux64/libexec
    Program succeed.
  5. Run example:
    ./bin/host
    Example sample output:
