We consider a randomized on-line scheduling problem where each job has to be scheduled on any of m identical processors. The objective is to minimize the expected makespan. We show that the competitive ratio of any randomized algorithm for m = 3 processors must be strictly greater than 27 19 .

We consider an on-line list scheduling problem of multi-core processor tasks with virtualization to minimize makespan. The competitive ratio of an on-line algorithm is shown for every specific m, where m is the number of processors. Better on-line algorithms are presented for a small number of proce
A set of tasks has to be scheduled on three processors and each task requires that a set of the processors be available for a given processing time. The objective of the problem is to determine a nonpreemptive schedule with minimum makespan. The problem is known to be NP-hard in the strong sense. A
