Limiting the number of cpus available for use

A number of the algorithms in the CLC Science Server will, in the case of large jobs, use all the cores available on your system to make the analysis as fast as possible. If you wish to restrict this to a predefined number of cores, this can be done with a properties file: Create a text file called cpu.properties and save it in the settings folder under the CLC Science Server installation directory.

The cpu.properties file should include one line like this:

maxcores = 1

Restart the CLC Science Server if you create or change this file for these settings to take effect.

Instead of 1 you write the maximum number of cores that the CLC Science Server is allowed to use. Please note that this is not a guarantee that the CLC Science Server will never use more cores than specified, but that will be for very brief and infrequent peaks and should not affect performance of other applications running on your system.
