3.8.1. Running the M2M Mode Demonstration Application

The M2M dataflow model uses the dla_benchmark demonstration application. The S2M bitstream supports both the M2M dataflow model and the S2M dataflow model.

You must know the host name of the SoC FPGA development kit. If you do not know the development kit host name, go back to Determining the SoC FPGA Development Kit IP Address before continuing here.

To run inference on the SoC FPGA development kit:
  1. Open an SSH connection to the SoC FPGA development kit:
    1. Start a new terminal session
    2. Run the following command:
      build-host:$ ssh <devkit_hostname>

      Where <devkit_hostname> is the host name you determined in Determining the SoC FPGA Development Kit IP Address.

      Continuing the example from Determining the SoC FPGA Development Kit IP Address, the following command would open an SSH connection:
      build-host:$ ssh arria10-62747948036a.local
  2. In the SSH terminal, run the following commands:
    export compiled_model=~/resnet-50-tf/RN50_Performance_b1.bin
    export imgdir=~/resnet-50-tf/sample_images
    export archfile=~/resnet-50-tf/<architecture file>
    cd ~/app
    export COREDLA_ROOT=/home/root/app
    ./dla_benchmark \
       -b=1 \
       -cm $compiled_model \
       -d=HETERO:FPGA,CPU \
       -i $imgdir \
       -niter=8 \
       -plugin ./plugins.xml \
       -arch_file $archfile \
       -api=async \
       -groundtruth_loc $imgdir/TF_ground_truth.txt \
       -perf_est \
       -nireq=4 \
       -bgr
    where <architecture file> is one of the following files, depending on your development kit:
    • Agilex™ 7 FPGA I-Series Transceiver-SoC Development Kit
      AGX7_Performance.arch
    • Arria® 10 SX SoC FPGA Development Kit
      A10_Performance.arch
The dla_benchmark command generates output similar to the following example output for each step. This example output was generated using an Agilex™ 7 FPGA I-Series Transceiver-SoC Development Kit.
