Scale-Out Processors

Babak Falsafi, Michael Ferdman, Boris Robert Grot, Yusuf Onur Koçberber, Pejman Lotfi Kamran, Stavros Volos, Javier Picorel Obando, Al Mutaz Adileh, Dorde Jevdic

Scale-out datacenters mandate high per-server throughput to get the maximum benefit from the large TCO investment. Emerging applications (e.g., data serving and web search) that run in these datacenters operate on vast datasets that are not accommodated by ...

Toward Dark Silicon in Servers

Anastasia Ailamaki, Babak Falsafi, Michael Ferdman

Server chips will not scale beyond a few tens to low hundreds of cores, and an increasing fraction of the chip in future technologies will be dark silicon that we cannot afford to power. Specialized multicore processors, however, can leverage the underutil ...

Cuckoo Directory: A Scalable Directory for Many-Core Systems

Babak Falsafi, Michael Ferdman, Pejman Lotfi Kamran, Ken Balet

Growing core counts have highlighted the need for scalable on-chip coherence mechanisms. The increase in the number of on-chip cores exposes the energy and area costs of scaling the directories. Duplicate-tag based directories require highly associative st ...

TurboTag: Lookup Filtering to Reduce Coherence Directory Power

Babak Falsafi, Michael Ferdman, Pejman Lotfi Kamran, Daniel Crisan

On-chip coherence directories of today’s multi-core systems are not energy efficient. Coherence directories dissipate a significant fraction of their power on unnecessary lookups when running commercial server and scientific workloads. These workloads have ...

Making Address-Correlated Prefetching Practical

Anastasia Ailamaki, Babak Falsafi, Michael Ferdman

Despite a decade of research demonstrating its efficacy, address-correlated prefetching has never been implemented in a shipping processor because it requires megabytes of metadata—too large to store practically on chip. New storage-, latency-, and bandwid ...

Near-Optimal Cache Block Placement with Reactive Nonuniform Cache Architectures

Anastasia Ailamaki, Babak Falsafi, Michael Ferdman

The growing core counts and caches of modern processors result in data access latency becoming a function of the data's physical location in the cache. Thus, the placement of cache blocks determines the cache's performance. Reactive nonuniform cache archit ...
