Just a quick question for those in the know.
Does Condor's implementation of concurrency limits work across pools
that allow flocking between them?
My simple understanding from reading the manual would be no. It only works
within a pool, as it relies on the collector/negotiator for enforcement?
If that is the case, then is it possible to setup a global concurrency limit
across multiple pools?
At this stage this is a slightly academic question but may be necessary for
us in the future.
Concurrency limits are scoped to a pool. The negotiator is responsible
for managing the concurrency limits.
Flocking is a schedd opportunistically talking to a negotiator in a
foreign pool. A foreign pool where the administrators have explicitly
allowed you to flock.
You can construct a global concurrency limit, assuming you can
configuration on the flock of negotiators.
What's the use case you're considering?
