    Description

      There's some bugs in the FifoScheduler atm - doesn't distribute tasks across nodes and some headroom (available resource) issues.
      That's not the best experience for users trying out the 2.0 branch. The CS with the default configuration of a single queue behaves the same as the FifoScheduler and doesn't have these issues.
