Pseudo code for an example handle-event routine is provided below in the “EXAMPLE ROUTINES” section. The cost function, cost(s,c), is a function that helps determine the suitability of assigning c to scheduling object s. The cost function can depend on a variety of parameters such as the size of the wait queues, the node traversal distance between s and the original scheduling node for c (to increase the probability that cache entries will be reused), and the history of the virtual processor, the physical-processor, and the continuation. If the wait queues of the scheduler objects close to s already contain too many continuations, then it may take a relatively longer time until any newly added continuation is scheduled for execution. Example conditions contributing to cost(s,c) are described below, and the conditions can be customized as applicable.
Costs
Cost functions are used to evaluate options when selecting continuations and scheduling objects. Cost functions can be expressed as the summation of a sum of weighted factors: cost=+w1f1x1+w2f2x2+ . . . +wnfnxn,
where wi indicates the importance of the corresponding factor and xi indicates an exponential.
