CAOS: Workshop onn Computer Architecture and the Operating System co-design
---------------------------------------------------------------------------
Multi-core and/or multi-threaded architectures are monopolizing the market, from embedded systems to supercomputers. However, achieving high performance with these modern systems has become a complex task: as the number of cores per chip and/or the number of hardware threads per core continue to increase, new challenges arise in terms of scheduling, power, temperature, scalability, design complexity, efficiency, throughput, heterogeneity, etc. Performance is not the only important metric anymore, and new metrics (such as security, power, total throughput, Quality of Service) are becoming more and more important. It seems clear that neither the hardware nor the software alone can achieve the desired performance and, at the same time, be compliant with these constraints. The answer to these new challenges comes from hardware-software co-design. Computer Architectures (CA) and Operating Systems (OS) should interact through a well-defined interface, exchanging run-time information, monitoring application progress and needs, and enforcing resource management.
This workshop aims to bring together researchers and engineers from academia and industry to share ideas and research directions in Computer Architecture and Operating System co-design and interaction. Authors are invited to submit innovative manuscripts in all areas of parallel and distributed processing, real-time systems, HPC systems and commercial/server systems.
Topics of interest
Papers are sought on topics including, but not limited to:
* Architectural and OS support for power and thermal management
* Architectural and OS support for scheduling applications on emerging multi-core systems
* Benchmarking and characterization of OS activity in multi-core architectures
* Architectural and OS support for virtualization
* Architectural and OS support to manage processor resource allocation and heterogeneity for Quality of Service
* Simulation tools for full system simulation
The workshop provides a forum to discuss the latest proposals in computer architecture and OS and to bring ideas and research problems to the attention of the audience.
We will prioritize papers reporting from on-going work that address cross-cutting issues and provide thought-provoking insights into the main themes. Proceedings with accepted papers will be made available at the workshop.
