[phenixbb] processor usage controlin DEN

[miyatake]

Dear phenixbb,

Hello, 

I run DEN refinements using GUI (dev-1439).

I wonder whether I can control the number of the 
processor used during the DEN refinement.

I know that we can use nproc in command line, but
I'd like use it in GUI.


Best regards,
