Mark can confirm is this is correct, but I think that as long as one of the 2 endpoints has the full pScheduler installed, you can use the --assist flag to help with this too.

 

It depends on what you’re trying to accomplish.

 

To run any two-participant test (throughput, simplestream) between systems A and B, all both must have a functioning pScheduler.  A or B can be tasked remotely by system C that has the pscheduler-core package installed:

 

            [user@C]$ pscheduler task --assist A throughput --source A --dest B

 

You can also install perfsonar-tools, but that installs more than is needed to talk to pScheduler.  The --assist switch points the CLI at a pScheduler server that can be used to carry out functions like converting the command-line arguments to the JSON expected by the pScheduler API.  (For reasons I won’t go into here, the CLI can’t do that on its own.)

 

As I said earlier, we don’t have a lightweight way to do basic non-pScheduler-to-pScheduler tests.  It is technically possible and we might consider something like that for a future release if there’s enough demand for it and we have the development cycles.
