Exploring energy-efficient transactional memory at HiPEAC 2015

Thu, 2015-02-19

Osman Ünsal presenting a keynote on energy-efficient transactional memory during HiPEAC 2015


Energy-efficient transactional memory was the topic of a presentation by ParaDIME researcher Osman Ünsal (Barcelona Supercomputing Center - BSC) at the final Euro-TM workshop, co-located with the 2015 HiPEAC conference in Amsterdam on 19 January 2015.

Transactional memories offer an alternative programming model which may simplify the development and testing of concurrent programs, enhance code reliability and boost productivity. Academic research in the field has recently been followed by interest in the commercial sector: processors with transactional memory support have recently become available (IBM BGQ, IBM Z-series, IBM Power8, Intel Haswell), making it possible to measure and quantify energy-related aspects.

The presentation provided the research background before exploring energy-efficient hardware transactional memory and research on error detection and transactional memory for energy-efficient computing below safe operation margins.  

In addition, along with BSC researchers Adrián Cristal and Gülay Yalçın and other experts in the field from across Europe, Dr Ünsal has also contributed to the final Euro-TM publication, Transactional Memory. Foundations, Algorithms, Tools, and Applications on the topic of reliability and transactional memory.

The keynote is available for download below.
