Recent Developments in Cache Coherence Protocols

"Source-Broadcast" is emerging as a class of cache coherence protocols implemented over point-to-point processor interconnects, combining the low latency of snoopy-based protocols with the scalability of directory-based protocols. The Quick Path Interconnect (QPI), recently introduced by Intel to replace the Front Side Bus, is the first commercial example to employ a source-broadcast protocol. I will describe variations and trade-offs of source-broadcast protocols and contrast them to the AMD Hypertransport approach.

James Goodman is a professor of computer science at the University of Auckland in Auckland, New Zealand, and emeritus professor at the University of Wisconsin-Madison. Goodman received a PhD from the University of California, Berkeley in 1980. He joined the faculty at the University of Wisconsin-Madison the same year as an assistant professor of computer science. Goodman's research is focused mainly on computer architecture: the hardware/software interface. His current interests are primarily focused on support for Transactional Memory. Goodman is most famous for his paper on "Using cache memory to reduce processor-memory traffic" where he was the first to describe snooping cache coherence protocols.

Hosted by Dirk Grunwald.


The Department holds colloquia throughout the Fall and Spring semesters. These colloquia, open to the public, are typically held on Thursday afternoons, but sometimes occur at other times as well. If you would like to receive email notification of upcoming colloquia, subscribe to our Colloquia Mailing List. If you would like to schedule a colloquium, see Colloquium Scheduling.

Sign language interpreters are available upon request. Please contact Stephanie Morris at least five days prior to the colloquium.
