Workshop Overview and Topics:

Operating systems (OS) constitute a major software component and are essential to any computing system. Commercial and server workloads such as online transaction processing, database, file/e-mail servers involve significant OS-level activity. The interactions between OS and emerging architectures (e.g. homogeneous and heterogeneous chip multiprocessors, simultaneous multithreading systems) / technology (e.g. hardware-assisted virtualization) are projected to continuously increase. To optimize system performance/power/reliability/security, it is important to facilitate efficient interaction and cooperation between the two constantly evolving components - computer architecture and OS.

This workshop focuses on characterizing, modeling, and optimizing the interaction between OS and hardware in the light of emerging architecture paradigms, workloads, and computing technology. Topics of particular interest include, but are not limited to:

  • Architectural support and mechanisms for OS functionality and services
  • OS support for emerging computer architectures
  • Architectural support for virtual machines and hypervisors
  • Implications of hardware virtualization and virtual machines on OS design
  • Frameworks and tools for full-system simulation
  • Techniques for mitigating the bottlenecks of OS execution
  • OS-aware microarchitecture (e.g. predictor, cache, and execution unit) design
  • Performance, power, dependability, and security in OS
  • Evaluation of the interactions and interference between OS and user applications
  • Workload variability issues full-system evaluation
  • Effect of OS mechanisms (e.g. scheduling, resource management) on emerging architectures
  • Characterization of OS activity in existing and emerging workloads
  • Leveraging OS to optimize reliability/thermal/power
  • Architecture and OS issues in data centers
  • Architecture and OS support for cloud computing
  • Implications of hardware virtualization and virtual machines on OS design
  • Hardware accelerators for important OS services (e.g., networking, data copying)
  • OS-intensive benchmark suites
  • Architecture/OS support for hardware accelerators (e.g., fixed functions, GPUs)

Furthermore, the workshop aims at providing a forum for researchers, engineers, and students from academia and industry to discuss their latest research in computer architecture and OS, to bring their ideas and research problems to the attention of others, and to obtain valuable and instant feedback from fellow researchers.
