摘要

This paper presents a performance evaluation of the interactions between local sequential processes running on behalf of interactive applications and parallel processes running as part of an overall parallel application on a nonded-icated cluster environment. To control the interactions between the two types of processes we propose to constrain the scheduling of local interactive processes by a measure of the maximum response time expected by the workstation (WS) user. The measure is assumed obtained through empirical studies. We propose a scheduling scheme that within the max-response time cycle computes time quanta to satisfy both local interactive processes present in the system and the parallel task process. Simulation results have shown the effectiveness of the proposed method in allowing the parallel tasks to ensure a minimum speedup even in heavy loaded situations and to maximize the speedup adaptively depending on the load conditions. In addition, the simulation results revealed the sensitivity of the interactions to factors such as interactive job demands, parallel job demand, and arrival rate of interactive jobs among others.
