The MASCOTS conference is a well-established forum for state-of-the-art research on the measurement, modeling, and performance analysis of computer systems and networks, and is cosponsored by the IEEE and ACM (approval pending). The 20th edition of this conference will take place August 7-9, 2012 in Arlington, Virginia (near Washington DC), USA. The conference will bring together academics and industry practitioners to present and discuss their latest research results. The technical program for the 3-day conference will include keynote talks, refereed papers, and posters. The conference organizers encourage researchers worldwide to submit their latest work in computer system performance analysis and evaluation, with results of theoretical and/or practical significance. We encourage researchers world-wide to submit original technical papers describing research in the areas of computer networks and computer systems performance evaluation. Topics of interest include, but are not limited to:

• Computer Architecture
• Computer Networks
• Distributed/Parallel Systems
• Industrial Practice and Experience
• Internetworking Protocols
• Multimedia Systems
• Performance Evaluation Methodologies
• Pervasive Web and Mobility
• Sensor Networks
