Licensing - The difference between node-locked and floating license.
What is the difference between a node-locked and a floating license?
Xilinx offers both node-locked and floating (or network floating server) licenses.
A node-locked license is an encrypted "key" that is locked to a specific machine or dongle. The license is uncounted, meaning that there can be an unlimited number of simultaneous runs (by any one user) on the single machine.
A network floating license allows a user to use a license from any machine that can access the identified license server. An encrypted "key" is locked to a license server host that runs the FLEX license server daemon. The license is "counted," meaning that the FLEX license manager keeps track of the number of "seats" hosted by that server.
