HomeCLC FAQ - CLC licenses and myCLCLicense questionsWhat is a static license and what is a network license?

1.1. What is a static license and what is a network license?

When purchasing software like CLC Workbenches, commercial Workbench plugins for the CLC Assembly Cell, two types of licenses, static licenses and network licenses, are available.

CLC Server analysis products use static licenses for single servers, for master server+CLC job nodes and for the master server in a grid node setup. Grid workers are licensed using network licenses.

The two license types are explained with reference to CLC Workbenches on our website at:


Key points about these license types are also found below.


Static licenses

  • These are held on the same machine as the software is running on, generally within the installation area of the software.
  • A tool specific to the software you are licensing, e.g. the CLC Genomics Workbench , is used to download a license file.
  • A single static license provides a license for a particular machine, allowing the licensed software, e.g. a CLC Workbench, to run on that machine. Users sharing a static license would need to work on the same machine.

Limitations: Static licenses for CLC Workbenches and the CLC Assembly Cell can be used on machines with 64 or fewer cores. For use on machines with a larger number of cores, you will need a network license.


Network licenses

  • Network licenses are served using the CLC License Server software, (not the analysis software).
  • Analysis software, for example, a CLC Workbench, is then configured to contact the CLC License Server at start up to request one of the network licenses.
  • A download tool specific to the CLC License Server software is used to download a license file.
  • A single network license can be used by one user at a time, but can be used on any machine that can contact the CLC License Server. Two network licenses would allow the analysis software to be run on two machines simultaneously. Users sharing a network license can work on different machines, with the maximum number of simultaneous users being the number of network licenses held for a given product.
