Re: Firefly-8.0.1 is not using all the cores of processor...

By default FF doesn't permit you to overwrite the output file. This is an origin of the problem. Read very carefully "Command line" section from the manual to better understand a meaning of the keys. I usually use :

mpirun -np ## SOMEPATH/firefly -f -p -r -stdext -f -f -f  -ex SOMEPATH -i INPUT -o OUTPUT -t SOMEPATH

Once again. Read VERY CAREFULLY command line section.

Good luck.

Pavel.
