Limit cores of CellProfiler 2.1.0


As I understood correctly, the ‘new’ CellProfiler 2.1.0 makes use of multiple cores when possible. I run CP 2.1.0 on a remote machine by the commandline interface. On that machine it is not appreciated to confiscate all available cores.

What is the command line option to limit the cores of CellProfiler 2.1.0 to a fixed number?

Thanks in advance,


Hi Bas,
I assume that you are running CP “headless”, i.e., without the graphical user interface by using the -c flag? If so, CP is set to only use one core at a time in this mode; you can see this post for more details.
