A high performance routing engine
24th ACM/IEEE conference proceedings on Design automation conference - DAC '87, 1987A hardware architecture for implementing Lee based routing algorithms is described. The design features hardware implementations of the main data structures and parallelism among a number of specialised processing elements. An engine based on this architecture has been constructed which executes a sophisticated cost-based algorithm 40 times faster than

Failure caused by poor performance renders a system just as useless as failure caused by functional errors, and can be even more expensive to correct. For many years, performance in software systems has been achieved through a ‘fix-it-later‘ approach, using optimisation and tuning techniques. Recent evidence shows that, with the increased use of highly

Reverse Engineering for Software Performance Engineering
14th Working Conference on Reverse Engineering (WCRE 2007), 2007Software reverse engineering can benefit from software performance engineering (SPE) techniques and vice versa. Reverse engineering's system artifacts satisfy SPE's need for a sequence of a software system in order to quantitatively analyze the system's performance characteristics.

Proceedings of the third international workshop on Large-scale system and application performance, 2011
We discuss the need for a more principled approach to the management of the performance of applications for petascale platforms and outline some initial successes, related to the Blue Waters project.

Putting Performance Engineering into Model-Driven Engineering: Model-Driven Performance Engineering
2008Late identification of performance problems can lead to significant additional development costs. Hence, it is necessary to address performance in several development phases by performing a performance engineering process. We show that Model-Driven Engineering (MDE) specifics can be utilised for performance engineering.

2007 IEEE International Conference on Information Reuse and Integration, 2007
This paper specifically deals with patterns topology or pattern language for performance evaluation, a cognitive process involved in producing and understanding different concepts of patterns in this discipline. It also explains how this language can be used to obtain the relationship between certain stable patterns, exhibiting a rich set of behaviors ...

Performance Engineering Education
Companion of the 2019 ACM/SPEC International Conference on Performance Engineering, 2017The successful development and marketing of commercial computer/communication systems requires the ability to quantify their performance and related metrics. Specifically, one should be able to demonstrate that projected customer requirements (QoS, QoE) are met, be able to identify bottlenecks, be able to evaluate and compare different configurations ...

Performance Management in Software Engineering
International Journal of Information Technology Project Management, 2011Performance measurement in software engineering has to meet a multiplicity of challenges. Oftentimes, traditional metrics focus on sequential development instead of using incremental and iterative development. Output is measured on a pure quantitative (e.g., SLOC), quality-disregarding basis.
