Message: Protocol error

Symptom: Protocol error message

Solution: Change firewall settings or debugging port

If you receive a "Protocol error" message, you need to change your firewall settings or change the debugging port in the Intel® SDK for OpenCL™ Applications - Debugger plug-in for Microsoft Visual Studio* IDE.

Note

The default debugging port is 56203.

To change the debugging port number for the CPU or GPU system, do the following:

  1. Run the Visual Studio IDE.
  2. Select Tools > Intel Code Builder for OpenCL API > OpenCL API Debugger > Options.
  3. Check the Use Custom Port check box of the appropriate system
  4. Enter the correct port in the CPU/GPU Kernel Debugging Port Number field.

Note

If the Use Custom Port check box is unavailable, switch to the Basic Settings tab and check the Enable OpenCL Kernel Debugging check box.
