Performance evaluation of scheduling policies in symmetric multiprocessing environments
2009
2009 IEEE International Symposium on Modeling, Analysis & Simulation of Computer and Telecommunication Systems
Preserved Fulltext
In particular, we are interested in the influence of multiprocessor load balancing on software performance. ...
For example, an optimal scheduling policy for multi-server systems, such as shortest remaining processing time (SRPT) for single-server systems, is not yet known in queueing theory. ...
One of the major influences for software performance in SMP systems is the multiprocessor load-balancing policy implemented in general purpose operating system (GPOS) schedulers. ...
