The Multicore Revolution
Prof. Maurice Herlihy,
Brown University, USA –
Abstract:
Computer architecture is undergoing, if not another revolution, then a vigorous shaking-up. The major chip manufacturers have, for the time being, mostly given up trying to make processors run faster. Instead, they have switched to “multicore” architectures, in which multiple processors (cores) communicate directly through shared hardware caches, providing increased concurrency instead of increased clock speed.
As a result, system designers and software engineers can no longer rely on increasing clock speed to hide software bloat. Instead, they must somehow learn to make effective use of increasing parallelism. This adaptation will not be easy. Conventional synchronization techniques based on locks and conditions are unlikely to be effective in such a demanding environment. Coarse-grained locks, which protect relatively large amounts of data, do not scale, and fine-grained locks introduce substantial software engineering problems. As a result, the community has increasingly turned to hardare and software models based on atomic transactions.
This talk will survey the area, with a focus on open research problems.
Hosts:Luís Rodrigues and João Cachopo

The HUB Winter Meeting aims at bringing together researchers and administrators from the 5 INESC institutes, affiliated higher education institutions in Portugal and abroad, with key European and global players, to:
– Discuss key research and innovation issues at EU level.
– Inform institutional policy and strategy.
– Exchange best-practices about R&I management, career development and policy positioning.
– Promote, discuss and deliver vision, visibility, networking and impactful communication.
– Create, identify and deepen partnerships and collaboration opportunities for collaborative R&I.
