Virtual Ways: Low-Cost Coherence for Instruction Set Extensions with Architecturally Visible Storage

Paolo Ienne, Edoardo Charbon, Ties Jan Henderikus Kluter, Samuel Burri, Philip Brisk

Instruction set extensions (ISEs) improve the performance and energy consumption of application-specific processors. ISEs can use architecturally visible storage (AVS), localized compiler-controlled memories, to provide higher I/O bandwidth than reading da ...

OLTP on Hardware Islands

Anastasia Ailamaki, Pinar Tözün, Ippokratis Pandis, Danica Porobic, Miguel Sérgio De Oliveira Branco

Modern hardware is abundantly parallel and increasingly heterogeneous. The numerous processing cores have non-uniform access latencies to the main memory and to the processor caches, which causes variability in the communication costs. Unfortunately, datab ...

TurboTag: Lookup Filtering to Reduce Coherence Directory Power

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

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 ...
