Hi All,

When I run gurobi_cl from a "Terminal" window, I get the following:

>gurobi_cl

ERROR 10030: License has an error, License is for 8 cores, machine has 12 - license file '/opt/gurobi/gurobi.lic'

I am running this in a windows environment with in PyCharm. We have a gurobi server set-up with a license for 24 cores. I'm not sure where its getting these numbers from.

Thanks,

Quang

  Hi Quang,

  Please check which license you are actually using by running \(\texttt{gurobi_cl --license}\) and verify that this is indeed the license you want to use. You can specify another license file via the environment variable GRB_LICENSE_FILE.

  Cheers,
  Matthias
