You can restrict the number of cores that can be used by:
- Creating a text file called
cpu.propertiesand saving it under the
settingsfolder in the Workbench installation directory.
- Editing that file, entering a single line like this:
maxcores = 3where 3 should be replaced by the maximum number of cores to be used by a given instance tool, like read mapping or de novo assembly. If several such analyses are run concurrently on the Workbench, each of these would be able to use up to this maximum number of cores if needed.
- Restart the Workbench.
Please note that configuring the
maxcores setting is not a guarantee that the Workbench will never use more than the number of cores specified. However, the use of any higher number of cores would be for very brief and infrequent peaks and should not affect performance of other applications running on your system.
