Port Usage

The GPU PerfClient communicates with the GPU PerfServer (locally and remotely) using TCP/IP port 80 by default.

GPU PerfStudio uses port 80 because the tool turns your application into a primitive web server that can service requests from the GPU PerfClient.

If you wish to change the port number you have to do it on both the client and server using the client and server options (Server Options, Client Options).

If there is a port miss match then the client will not be able to communicate with the server.
