On-Line Load Balancing of Temporary Tasks on Identical Machines

چکیده
We prove an exact lower bound of 2 1 m on the competitive ratio of any deterministic algorithm for load balancing of temporary tasks on m identical machines. We also show a lower bound of 2 1 m for randomized algorithms for small m and 2 2 m+1 for general m. If in addition, we restrict the sequence to polynomial length, then the lower bound for randomized algorithms becomes 2 O( log logm logm ) for general m.

Proper planning of assembly lines is one of the production managers’ concerns at the tactical level so that it would be possible to use the machine capacity, reduce operating costs and deliver customer orders on time. The lack of an efficient method in balancing assembly line can create threatening problems for manufacturing organizations. The use of assembly line balancing methods cannot balan...
متن کاملLoad Balancing of Temporary Tasks in the lp Norm
We consider the on-line load balancing problem where there are m identical machines (servers). Jobs arrive at arbitrary times, where each job has a weight and a duration. A job has to be assigned upon its arrival to exactly one of the machines. The duration of each job becomes known only upon its termination (this is called temporary tasks of unknown durations). Once a job has been assigned to ...
متن کاملLoad Balancing for Response Time
A centralized scheduler must assign tasks to servers, processing on-line a sequence of task arrivals and departures. Each task runs for an unknown length of time, but comes with a weight that measures resource utilization per unit time. The response time of a server is the sum of the weights of the tasks assigned to it. The goal is to minimize the maximum response time, i.e., load, of any serve...
متن کاملOn-line restricted assignment of temporary tasks with unknown durations
We consider load balancing of temporary tasks on m machines in the restricted assignment model. It is known that the best competitive ratio for this problem is Θ( √ m). This bound is not achieved by the greedy algorithm whose competitive ratio is known to be Ω(m 2 3 ). We give an alternative analysis to the greedy algorithm which is better than the known analysis for relatively small values of ...
متن کاملResource Augmentation in Load Balancing
We consider load-balancing in the following setting. The on-line algorithm is allowed to use n machines, whereas the optimal off-line algorithm is limited to m machines, for some fixed m < n. We show that while the greedy algorithm has a competitive ratio which decays linearly in the inverse of n/m, the best on-line algorithm has a ratio which decays exponentially in n/m. Specifically, we give ...
