WIOV 2011 - WIOV 2011 : 3rd Workshop on I/O Virtualization

Virtualization technology has grown beyond server systems to include desktops, notebooks, and even mobile devices. The rich settings in which virtualized systems are used range from cloud computing infrastructures requiring access to high-end I/O devices like GPUs and networks to the many devices present in embedded and mobile systems. Consequent requirements imposed on I/O include the need for extreme-scale performance in high performance or low latency systems; fairness in device sharing in cloud and server systems, which includes online methods for understanding the I/O behavior of applications; trusted I/O both for cloud and for mobile systems; and low overhead and reliable device access in the mobile or embedded domains.
While I/O systems have a long history of using abstraction to shield applications from the intricacies of devices and storage systems, this workshop's focus is on the interplay of I/O with virtualization and cloud technologies. Our goal is to provide a forum to discuss the impact and challenges of I/O virtualization along multiple dimensions, including: the application domains in which virtualized solutions are used and the subsystems involved; platform or hardware support for I/O virtualization; the virtual machine monitor; the guest operating system; the processor, GPU, memory, and I/O subsystems. Also of interest are higher-level virtualization solutions, such as those concerning API virtualization, new virtual I/O APIs like those used for cloud storage, and innovative approaches to device virtualization in cloud computing and in the mobile domain. We welcome papers that describe new challenges and solutions in I/O virtualization and papers that describe novel approaches to solving known problems. The final program will consist of both reviewed submissions and invited talks. The invited talks will focus on open problems in I/O virtualization and will be accessible to a broad audience.
