Users of Gurobi Remote Services will fall into one of three possible roles: cluster administrator, administrator, or client. The cluster administrator is in charge of setting up the cluster, adding and removing nodes, etc. In contrast, administrators do things like monitor the length of the server queue, kill jobs, etc. Clients are the people that run the programs on client machines that ultimately submit jobs to a Compute Server cluster. Note that the client role and the administrator role are often, but not always, performed by the same person. The cluster administrator role is typically performed by a system administrator.

Gurobi includes a number of tools that are relevant to the people in these roles. These are all covered in much more detail later on, but we'll describe how they fit with the various roles in this section.

Note that a Gurobi Remote Services cluster will have three different passwords, corresponding to these different roles. You will need to provide the appropriate password for the type of Remote Services task you wish to perform. Again, the details will be discussed shortly.
