Try to open two bash prompts, in one use R a

Use "top" at the bash promp
If you use gkrellm, you'll get a plot of each core's activity so it's

Use "top" at the bash prompt.
Read about the "mc.cores" parameter to mclapply.
Make a simplified example version of your analysis and post your question in
the context of that example [1][2][3]. You will learn about the issues you are
dealing with in the process of trimming your problem, and wi
The effectiveness of parallelizing code, be it with mclapply or otherwise,
depends in large part on the code, which you failed to show.
I cannot answer your other question.
