We are experimenting with using Boinc to operate an internal grid for one specific application. I have successfully configured a server using the wrapper with our application and our initial tests using a grid of about 20 scattered machines have gone quite well.

As we run tests, and the tests complete, the clients on those 20 machines sit idle. When we generate a new job on the server, it takes some of the clients many hours (in one case over 24) to actually get new tasks. Of course, if I hit the update button on the client it gets new work right away and starts computing.

Is there a configuration where I could tell the clients to check for new work more frequently? I would like it to be on the order of minutes rather than hours. I understand why it needs to be the way it is in a global volunteer environment but for this use case I am hoping there is an easy way to override it without having to dig into/modify the source.

Yes, in the client control section of the project config file on the server.

In each scheduler reply, tell the clients to do another scheduler RPC after at most X seconds, regardless of whether they need work. This is useful, e.g., to ensure that in-progress jobs can be canceled in a bounded amount of time.

Thank you. That is exactly what I was looking for.
