A Concept of Modeling and Optimization of Applications in Large Scale Systems
MetadataPokaż pełny rekord
The chapter presents the idea that includes modeling and subsequent optimiza- tion of application execution on large scale parallel and distributed systems. The model considers performance, reliability and power consumption. It should allow easy modeling of various classes of applications while reflecting key parameters of both the applications and two classes of target systems: clusters and volunteer based systems. The chapter presents several applications of the approach: simulation of application execution on particular systems, optimization of assignment of several applications onto a complex environment that consists of several clusters and vol- unteer based systems as well as for assessment of best future system configurations for execution of predefined application sets.
