Testing a Client Computer
Before using the Gurobi Cloud, you should install and configure Gurobi Optimizer to run on the client computer(s). Installation instructions are in the Gurobi Optimizer Quick Start Guide. You can download the current version of Gurobi Optimizer from the Download section of the Gurobi website.
If you would like to test a client computer before trying the Gurobi
Cloud, a free test server is available at
csdemo.gurobi.com. With this test server, you can test and
diagnose any network connection issues without paying any charges for a
Gurobi Cloud instance. This test server is very limited in
bandwidth and computing resources: it should only be used
to test whether a computer can connect to a remote Gurobi Compute
Server. Please do not use this free server for any other testing or any
other purposes.
To try the test server, open a Command Prompt (on Windows) or a Terminal (Mac or Linux), then run the command:
gurobi_cl --server=csdemo.gurobi.com mymodel.mps
You should change mymodel.mps to any simple model file such as afiro.mps from the examples\data subdirectory. If it fails, here is a list of error messages and troubleshooting steps:
- All servers at capacity: The compute server is currently busy with other users; please wait or try again later
- No server available: The client cannot connect to the compute server, so please verify the following with your system administrator:
- The network firewall rules should allow the client computer to connect to ports 61000-65000 on csdemo.gurobi.com
- The client computer should not use a proxy server to communicate to the internet
