Distributed parallel: how to measure how many cores are really used on remote machine?

[Maciej Pilichowski]

Hello,

  I have local computer with 2 cores, and remote one with 4 cores. I 
run parallel always with -j+0.

  It seems that around 50% of the job is done locally, and 50% on 
remote machine. While I would expect around 20% and 80%.

  I am wondering if parallel checks the cores locally, gets the answer, 
2, and so running 2 tasks on remote machine too. Or if the transferring 
files is so limiting.

  So -- how to measure how many cores are really used on remote machine?

Kind regards,
