Submitting an Interactive Job

Once you are logged in, you can use gurobi_cl to submit a job:

Compute Server communication statistics:
  Sent: 0.002 MBytes in 9 msgs and 0.01s (0.26 MB/s)
  Received: 0.007 MBytes in 26 msgs and 0.09s (0.08 MB/s)

The initial log output indicates that a Compute Server job was created, that the Compute Server cluster had capacity available to run that job, and that an unencrypted HTTP connection was established with a server in that cluster. The log concludes with statistics about the communication performed between the client machine and the Compute Server. Note that the result file solution.sol is also retrieved.

This is an interactive optimization task because the connection with the job must be kept alive and the progress messages are displayed in real time. Also, stopping or killing the command terminates the job.
