چکیده
To support creation of nimble applications for computational grids, the authors believe one must eliminate the barrier that separates program creation from execution and post-mortem optimization. This paper outlines an approach to dynamic performance adaptation and distributed optimization in the grid environment based on a suite of performance instrumentation, analysis, and presentation tools that includes distributed performance sensors and resource policy actuators, fuzzy logic rule bases for adaptive control, and immersive visualization systems for real-time visualization and direct manipulation of software behavior.

Real-Time Performance Monitoring, Adaptive Control, and Interactive Steering of Computational Grids
The scope of high-performance computing is rapidly expanding from single parallel systems to clusters of heterogeneous sequential and parallel systems. Moreover, as applications become more complex, they grow more irregular, with data-dependent execution behavior, and more dynamic, with time-varying resource demands. Consequently, even small changes in application structure can lead to large ch...
متن کاملSelf-Starting Control Chart and Post Signal Diagnostics for Monitoring Project Earned Value Management Indices
Earned value management (EVM) is a well-known approach in a project control system which uses some indices to track schedule and cost performance of a project. In this paper, a new statistical framework based on self-starting monitoring and change point estimation is proposed to monitor correlated EVM indices which are usually auto-correlated over time and non-normally distributed. Also, a new ...
متن کاملAssessment of BAM with ANP Approach; Case Study: Bank Sepah
In today's business environment in which coordination and adaptation with constant changes are the only ways of survival, real-time monitoring of activities and making the decisions accordingly are necessary. Since performance measurement cannot be managed independent of business processes, Business Activity Monitoring (BAM) systems should monitor performance metrics based on business processes...
