More than 60 participants from roughly 20 different organizations attended this year’s Symposium on Software Performance (SOSP 2014), which took place from November 26 to 28, 2014 in Stuttgart, Germany. SOSP aims to bring together researchers and practitioners interested in all facets of software performance, ranging from modeling and prediction to monitoring and runtime management. The symposium is organized by the three research groups Descartes, Kieker, and Palladio, who use this symposium also as a joint developer and community meeting.
