New paper: An Industrial Case Study of Performance and Cost Design Space Exploration

Heiko — Fri, 06 Jan 2012 11:11:35 +0000

This paper shows how our software tools Palladio and PerOpteryx were used in capacity planning for a web-based remote diagnostics system at ABB. It will be presented at the International Conference on Performance Engineering (ICPE 2012) in April in Boston, US.

PerOpteryx results: CPU Utilization vs. costs; each dot represents a generated design alternative for the system. The diagram shows the trade-off between performance and costs.

Impact?

I noticed that our 2009 article on the Palladio Component Model is currently the most cited article of the Journal of Systems and Software during the last 5 years (77 citations). My 2010 performance evaluation survey is the most downloaded article from Elsevier’s Performance Evaluation Journal from July 2010 to June 2011.

Many thanks to all readers and downloaders, I feel humbled by the apparent interest in these works!

Automated Transformation of Component-based Software Architecture Models to Queueing Petri Nets

New paper accepted at MASCOTS 2011: “This paper contributes a formal mapping from PCM to QPN models, implemented by means of an automated model-to-model transformation as part of a new PCM solution method based on simulation of QPNs. The limitations of the mapping and the accuracy and overhead of the new solution method compared to existing methods are evaluated in detail in the context of five case studies of different size and complexity. The new solution method proved to provide good accuracy with solution overhead up to 20 times lower compared to PCM’s reference solver.”
