I am currently running 4 subjects, each on a separate x11 window. With 19 subjects at hand and subsequent manual editing, I can't resist the temptation to open more x11 terminals and to submit more jobs. However, how do I know that I max out the machine's computing power?

Hard drive info

Processor Name: Intel Core i5

Processor Speed: 2.7GHz

Number of Processors: 1

Total number of cores: 4

Memory: 16GB

Thank you very much!

Sincerely,

Ye
