Workshop on The Influence of I/O on Microprocessor Architecture (IOM-2009)
February 15, 2009

Co-located with HPCA-15 in Raleigh, North Carolina – February 14-18, 2009.

Website: http://berkeley.intel-research.net/iom‐2009

Increasing dependency of applications on I/O, emergence of new
I/O technologies and integration lead us to believe that I/O will
have a profound influence on future microprocessor architecture.
The workshop solicits original papers on completed work, future
directions, position papers, and/or work-in progress papers in the
following areas. We encourage all to submit papers that bring out
new and interesting approaches even if they are in early stages of
development. The main goal is to have leading researchers in
academia and industry to meet and put their ideas on the table.
- Historical perspectives on how I/O subsystems have evolved
- Evaluation of existing I/O subsystems and implications
- Microprocessor core/cache architecture enhancements for
efficient I/O processing, I/O related data movement and
power management
- Relationships between typical programmable cores,
accelerators and I/O (tightly coupled communications and
computational accelerators)
- Software-Hardware partitioning of I/O processing
- Influence of I/O subsystem virtualization
- Architectural trade-offs when integrating various forms of I/O
(wireless or wired networking, storage, USB and high
performance interconnects)
- Integration styles – monolithic integration of existing discrete
designs or infusion of I/O into microprocessor cores
- Measurement, modeling and simulation paradigms to improve
the evaluation of processor-I/O interaction
