Slow Startup of QuantumATK

If you find QuantumATK slow to start, there can be several reasons. When things are set up properly, QuantumATK should fire up in a few seconds on Linux and it usually takes a bit longer on Windows. In both cases, keep the following things in mind:

  • Don’t make projects too large. The more files there are in your project, the more work for the software to both start up and close down. In particular, never turn your home directory or root directory into a project, import single files into the project if needed.

  • Sometimes startup is slower, sometimes faster. This depends on caching in the operating system.

  • QuantumATK needs to check out a license. If your connection to the license server is unstable, this can take some time.
