A runtime heuristic to selectively replicate tasks for application-specific reliability targets
Subasi, Omer; Yalcin, Gulay; Zyulkyarov, Ferad; Unsal, Osman Sabri; Labarta Mancho, Jesús José (Institute of Electrical and Electronics Engineers (IEEE), 2016)
Text en actes de congrés
Accés obertIn this paper we propose a runtime-based selective task replication technique for task-parallel high performance computing applications. Our selective task replication technique is automatic and does not require ... -
Circuit design of a novel adaptable and reliable L1 data cache
Seyedi, Azam; Yalcin, Gulay; Unsal, Osman Sabri; Cristal Kestelman, Adrián (2013)
Text en actes de congrés
Accés obertThis paper proposes a novel adaptable and reliable L1 data cache design (Adapcache) with the unique capability of automatically adapting itself for different supply voltage levels and providing the highest reliability. ... -
CRC-based memory reliability for task-parallel HPC applications
Subasi, Omer; Unsal, Osman Sabri; Labarta Mancho, Jesús José; Yalcin, Gulay; Cristal Kestelman, Adrián (Institute of Electrical and Electronics Engineers (IEEE), 2016)
Text en actes de congrés
Accés restringit per política de l'editorialMemory reliability will be one of the major concerns for future HPC and Exascale systems. This concern is mostly attributed to the expected massive increase in memory capacity and the number of memory devices in Exascale ... -
Designing and modelling selective replication for fault-tolerant HPC applications
Subasi, Omer; Yalcin, Gulay; Zyulkyarov, Ferad; Unsal, Osman Sabri; Labarta Mancho, Jesús José (Institute of Electrical and Electronics Engineers (IEEE), 2017)
Text en actes de congrés
Accés obertFail-stop errors and Silent Data Corruptions (SDCs) are the most common failure modes for High Performance Computing (HPC) applications. There are studies that address fail-stop errors and studies that address SDCs. However ... -
Designs for increasing reliability while reducing energy and increasing lifetime
Yalcin, Gulay (Universitat Politècnica de Catalunya, 2014-12-12)
Tesi
Accés obertIn the last decades, the computing technology experienced tremendous developments. For instance, transistors' feature size shrank to half at every two years as consistently from the first time Moore stated his law. ... -
FaulTM: Error detection and recovery using hardware transactional memory
Yalcin, Gulay; Unsal, Osman Sabri; Cristal Kestelman, Adrián (2013)
Text en actes de congrés
Accés restringit per política de l'editorialReliability is an essential concern for processor designers due to increasing transient and permanent fault rates. Executing instruction streams redundantly in chip multi processors (CMP) provides high reliability since ... -
FaulTM: Fault-tolerance using hardware transactional memory
Yalcin, Gulay; Unsal, Osman Sabri; Hur, Ibrahim; Cristal Kestelman, Adrián; Valero Cortés, Mateo (2010)
Text en actes de congrés
Accés obertFault-tolerance has become an essential concern for processor designers due to increasing soft-error rates. In this study, we are motivated by the fact that Transactional Memory (TM) hardware provides an ideal base upon ... -
FIMSIM: A fault injection infrastructure for microarchitectural simulators
Yalcin, Gulay; Unsal, Osman Sabri; Cristal Kestelman, Adrián; Valero Cortés, Mateo (2011)
Report de recerca
Accés obertFault injection is a widely used approach for experiment-based dependability evaluation in which faults can be injected to the hardware, to the simulator or to the software. Simulation based fault injection is more appealing ... -
