 Command Line Analysis

Use the CPU/FPGA Interaction analysis to assess the balance between CPU and FPGA in systems with FPGA hardware that run Data Parallel C++ (SYCL) or OpenCL™ applications. Review FPGA time spent executing kernels, overall time for memory transfers between the CPU and FPGA, and wait time impact on CPU and FPGA work loads.

Syntax

vtune
 -collect fpga-interaction [-knob <
knobName=knobValue
>] [--] <
target
>
For the most current information on available knobs (configuration options) for the CPU/FPGA Interaction analysis, enter:
vtune
 -help collect fpga-interaction
Example
This example runs the CPU/FPGA Interaction analysis on an application with stack collection enabled: 
vtune -collect fpga-interaction -knob enable-stack-collection=true -- /home/test/myApplication
