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
https://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=https://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 with a communication error, please verify with your system administrator that firewalls rules allow communication using HTTPS on default port 443. If you have to use a proxy server, Gurobi tools and libraries are compatible with standard proxy settings using environment variables HTTP_PROXY and HTTPS_PROXY. HTTPS_PROXY takes precedence over HTTP_PROXY for https requests. The values may be either a complete URL or a "host[:port]", in which case the "http" scheme is assumed.
If it fails with All servers at capacity message, it will mean that the server is currently busy with other users; please wait or try again later.
