A performance goal oriented processor allocation technique for centralized heterogeneous multi-cluster environments

This paper proposes a processor allocation technique named temporal look-ahead processor allocation (TLPA) that makes allocation decision by evaluating the allocation effects on subsequent jobs in the waiting queue. TLPA has two strengths. First, it takes multiple performance factors into account when making allocation decision. Second, it can be used to optimize different performance metrics. To evaluate the performance of TLPA, we compare TLPA with best-fit and fastest-first algorithms. Simulation results show that TLPA has up to 32.75 performance improvement over conventional processor allocation algorithms in terms of average turnaround time in various system configurations. © 2011 IEEE.
