Networks on Chips: Scalable interconnects for future systems on chips

Muhammad Ali, Michael Welzl, Martin Zwicknagl
2008 2008 4th European Conference on Circuits and Systems for Communications  
However, these buses are not scalable beyond a certain limit. In this case, the current interconnect infrastructure will become a bottleneck for the development of billion transistor chips.  ...  This new design paradigm has been termed with a variety of titles, but the most common and agreed upon one is Networks on Chips (NoCs).  ...  A NoC is percieved as a collection of computational, storage and I/O resources on-chip that are connected with each other via a network of routers or switches instead of being connected with point to point  ...

Modular Scalable I/O

E.P. Debenedictis, J.M. Delrosario
1993 Journal of Parallel and Distributed Computing  
We describe design issues for scalable I/O systems. I/O system modularity is the central issue. We identify the new information and algorithms responsible for high performance in scalable I/O.  ...  We show how to assign them to the parts of a scalable computer system so the result is modular. We built a modular I/O system and it is commercially available.  ...  MODULAR SCALABLE I/O The modularity property of an I/O system is directly responsible for ease of use.  ...

Remote I/O

Ian Foster, David Kohr, Rakesh Krishnaiyer, Jace Mogill
1997 Proceedings of the fifth workshop on I/O in parallel and distributed systems - IOPADS '97  
We argue instead for a remote I/O paradigm in which programs use familiar parallel I/O interfaces to access remote filesystems.  ...  As high-speed networks make it easier to use distributed resources, it becomes increasingly common that applications and their data are not colocated.  ...  Department of Energy, under Contract W-31-109-Eng-38, in support of the multiagency Scalable I/O project.  ...

Beyond block I/O

Michael Wei, John D. Davis, Ted Wobber, Mahesh Balakrishnan, Dahlia Malkhi
2013 Proceedings of the 6th International Systems and Storage Conference on - SYSTOR '13  
The basic block I/O interface used for interacting with storage devices hasn't changed much in 30 years.  ...  With the advent of very fast I/O devices based on solid-state memory, it becomes increasingly attractive to make many devices directly and concurrently available to many clients.  ...  And we especially thank Chuck Thacker and his team for building the Beehive system.  ...

Terascale I/O Solutions [chapter]

Nathan Stone, John Kochmar, Paul Nowoczynski, J. Ray Scott, Derek Simmel, Jason Sommerfield, Chad Vizino
2003 Lecture Notes in Computer Science  
These I/O solutions have a synergistic effect that is leveraged in their design, implementation and integration.  ...  PSC has enhanced the effective usability and utilization of this resource by providing custom I/O solutions in four key areas: high-performance communication, highperformance file migration, checkpoint  ...  Thus a compute job can, for example, pass a non-blocking file migration request to an I/O daemon and return to CPU-intensive compute tasks while the I/O daemon (a separate process) handles the I/O intensive  ...
