[Gretl-users] Question about parallel processing using the shell

Hello all, I am using the launch command in a loop to call out to a processor intensive estimation routine ( I am calling an exe file). My system only has 12 processor cores, so is there a way to limit the number of simultaneous processes to 12? Or should I just let windows handle it. Here are the specs of my setup: OS: Win 10 pro 64 bit grelt: latest git as of 2019-06-16 ram: 32gb CPU's: 2 x Hex-Core Intel Xeon Cheers, Logan P.S. I apologize if this is too far off topic.
