Run the Sample Application

Go to the

AMR_containers

folder:

cd <edge_insights_for_amr_path>/Edge_Insights_for_Autonomous_Mobile_Robots_<version>/AMR_containers

Run the command below to start the Docker container:

./run_interactive_docker.sh amr-ubuntu2004-full-flavour-sdk:<TAG> root

Copy the

matrix_multiply_vtune

in

tmp

and change directory to VTune™ Profiler:

cp -r /home/eiforamr/data_samples/matrix_multiply_vtune /tmp/matrix_multiply_vtune
cd /tmp/matrix_multiply_vtune

Build the Matrix Multiplication sample:

. /opt/intel/oneapi/setvars.sh
cmake .
make

Run the application with VTune™ Profiler:

sudo /opt/intel/oneapi/vtune/2021.2.0/bin64/vtune -collect gpu-hotspots -- ./matrix.dpcpp
