However, the achieved performance when a certain parallel program is executed is significantly lower than the maximal theoretical performance of the parallel computing system. The model-based performance evaluation may be used to support the performance-oriented program development for parallel computing systems. In this book chapter we present a hybrid approach for performance modeling and prediction of parallel computing systems, which combines mathematical modeling and discrete-event simulation. We use mathematical modeling to develop parameterized performance models for components of the system. Thereafter, we use discrete-event simulation to describe the structure of system and the interaction among its components. As a result, we obtain a high-level performance model, which combines the evaluation speed of mathematical models with the structure awareness and fidelity of the simulation model. We evaluate empirically our approach with a real-world material science program that comprises more than 15,000 lines of code.<\/jats:p>","DOI":"10.3233\/978-1-60750-004-9-54","type":"book-chapter","created":{"date-parts":[[2025,2,19]],"date-time":"2025-02-19T15:30:51Z","timestamp":1739979051000},"source":"Crossref","is-referenced-by-count":0,"title":["Hybrid Performance Modeling and Prediction of Large-Scale Parallel Systems"],"prefix":"10.3233","author":[{"family":"Pllana Sabri","sequence":"additional","affiliation":[]},{"family":"Benkner Siegfried","sequence":"additional","affiliation":[]},{"family":"Xhafa Fatos","sequence":"additional","affiliation":[]},{"family":"Barolli Leonard","sequence":"additional","affiliation":[]}],"member":"7437","container-title":["Advances in Parallel Computing","Parallel Programming, Models and Applications in Grid and P2P Systems"],"original-title":[],"deposited":{"date-parts":[[2025,2,19]],"date-time":"2025-02-19T15:41:17Z","timestamp":1739979677000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISSNISBN&issn=0927-5452&volume=17&spage=54"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-60750-004-9-54","relation":{},"ISSN":["0927-5452"],"issn-type":[{"value":"0927-5452","type":"print"}],"subject":[],"published":{"date-parts":[[2009]]}}}
