does this log file means that PLUMED is working in parallel?

[Ibrahim Mohamed]

i have a log file from GROMACS patched with plumed 2.7.3 and i dont know whether it is running in parallel or not. i am using 15 nodes with 32 cores per node a total of 480 cores.
i saw the video of the masterclass regarding the optimization of plumed and in the example they had a picture showing number of nodes equal to 1 and number of threads equal to 20.

but in the log file i have 400 nodes and 1 thread. is this correct?

log file:

PLUMED: PLUMED is starting
