Running Programs on Remote Computers

The Wolfram Symbolic Transfer Protocol (WSTP) allows you to call an external program from within the Wolfram Language even when that program is running on a remote computer. Typically, you need to start the program directly from the operating system on the remote computer. But then you can connect to it using commands within your Wolfram Language session.

Operating system on

This starts the program and tells it to create a new link.
fprog -linkcreate -linkprotocol TCPIP
The program responds with the specification of the link it has created.
Link created on:, 

Wolfram System session on

This connects to the link that has been created.
This now executes code in the external program on .

External programs that are created using or always contain the code that is needed to set up WSTP connections. If you start such programs directly from your operating system, they will prompt you to specify what kind of connection you want. Alternatively, if your operating system supports it, you can also give this information as a commandline argument to the external program.
