fpga-interaction Command Line Analysis

Use the CPU/FPGA Interaction analysis to assess the balance between the CPU and FPGA on systems with a discrete Intel® Arria® 10 FPGA running 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

$ amplxe-cl -collect fpga-interaction [-knob <knobName=knobValue>] [--] <target>

Knobs: sampling-interval, enable-stack-collection.

Note

For the most current information on available knobs (configuration options) for the CPU/FPGA Interaction analysis, enter:

$ amplxe-cl -help collect fpga-interaction

Example

The following example runs the CPU/FPGA Interaction analysis on the application with stack collection enabled:

$ amplxe-cl -collect fpga-interaction -knob enable-stack-collection=true -- /home/test/myApplication
