Submitting Interactive Jobs

The Gurobi command-line tool gurobi_cl can be used to submit optimization jobs. Once you have successfully executed the grbcluster login command, you can then submit a job using gurobi_cl. This is the example we used earlier in this document:

> gurobi_cl ResultFile=solution.sol stein9.mps
Using license file /opt/gurobi900/manager.lic
Set parameter CSManager to value http://server1:61080
Set parameter LogFile to value gurobi.log
Compute Server job ID: 1e9c304c-a5f2-4573-affa-ab924d992f7e
Capacity available on 'server1:61000' - connecting...
Established HTTP unencrypted connection
Gurobi Optimizer version 9.0.1 build v9.0.1rc0 (linux64)
Copyright (c) 2020, Gurobi Optimization, LLC
...

Optimal solution found (tolerance 1.00e-04)
Best objective 5.000000000000e+00, best bound 5.000000000000e+00, gap 0.0000%

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 terminate the job.
