Fleets: Scalable Services in a Factored Operating System
(2011-03-09)
Current monolithic operating systems are designed for uniprocessor systems, and their architecture reflects this. The rise of multicore and cloud computing is drastically changing the tradeoffs in operating system design. ...
BOOM: Broadcast Optimizations for On-chip Meshes
(2011-03-14)
Future many-core chips will require an on-chip network that can support broadcasts and multicasts at good power-performance. A vanilla on-chip network would send multiple unicast packets for each broadcast packet, resulting ...
The Case for a Factored Operating System (fos)
(2008-10-08)
The next decade will afford us computer chips with 1,000 - 10,000 cores on a single piece of silicon. Contemporary operating systems have been designed to operate on a single core or small number of cores and hence are not ...
Library Cache Coherence
(2011-05-02)
Directory-based cache coherence is a popular mechanism for chip multiprocessors and multicores. The directory protocol, however, requires multicast for invalidation messages and the collection of acknowledgement messages, ...
Scalable directoryless shared memory coherence using execution migration
(2010-11-22)
We introduce the concept of deadlock-free migration-based coherent shared memory to the NUCA family of architectures. Migration-based architectures move threads among cores to guarantee sequential semantics in large ...
Energy Scalability of On-Chip Interconnection Networks in Multicore Architectures
(2008-11-11)
On-chip interconnection networks (OCNs) such as point-to-point networks and buses form the communication backbone in systems-on-a-chip, multicore processors, and tiled processors. OCNs can consume significant portions of ...
