The specification introduces the following concepts: + +* Scheduling Segment - A sequence of code, on a single host, with +specific scheduling requirements +* Distributable Thread (DT) - A programming model abstraction for a +distributed task +* Pluggable Scheduler - Facilitate the use of multiple scheduling +disciplines +* Scheduling Points - To interact with the scheduler at the +application and ORB level + +This dir contains two pluggable schedulers: + +Fixed Priority Scheduler - This scheduler uses the OS scheduler to +schedule the various DTs dynamically entering and leaving the +system. The DTs are scheduled based on their importance. + +Most Important First (MIF) Scheduler - This scheduler uses a custom +MIF scheduler to schedule the DTs in the system. The tasks are +scheduled according to their importance. The scheduler maintains a +ready queue of DTs. When a DT enters the system it puts the DT in the +ready queue in order of its importance. It then activates the DT +of highest importance in the ready queue. So at any given time the +DT with the highest importance is running. -- cgit v1.2.1
