I am running a tool that definitely only uses one core. However, when I look at ``top`` I see that I am using a large portion of the available cores on the machine.

You may need to limit the maximum number of garbage collection threads being used by Java.
For example:
`` java -XX:ConcGCThreads=1 -jar gatk-protected.jar …….``
