Ayse K. Coskun, Auteur | 2017"Application performance variations can cause inefficiency in high-performance computing (HPC) systems. Here, Ayse discusses an automated way of diagnostic these variations." (Extrait de Circuit Cellar n°326)Article : texte imprimé
Ayse K. Coskun, Auteur | 2017"High-performance chips have significant heat generation variations across their various microarchitectural and circuit blocks. This article argues that hybrid and heterogeneous cooling methods that tackle the "hot spots" locally and use efficient cooling methods to remove the background heat offer the potential to substantially improve power efficiency.&...Article : texte imprimé
Ayse K. Coskun, Auteur | 2016"The growing use of intermittent renewables in power generation creates challenges for real-time supply and demand balance in the power grid. Emerging ancillary power markets provide incentives to consumers to perform demand response. This article discusses the benefits of using different types of energy storage technologies for smart grid ...Article : texte imprimé
Ayse K. Coskun, Auteur | 2016"Data center users today have little visibility into the performance characteristics and power consumption of the software and hardware components of the data center ; and the service providers at data centers have little visibility into user application performance requirements and critical metrics such as response time and throughtput. This article ...Article : texte imprimé
Ayse K. Coskun, Auteur | 2015"Data center energy/cooling efficiency work has mostly focused on raised-floor aircooled facilities. Today, traditional air cooling is being replaced by systems involving liquid cooling that provide enhanced airflow and cooling capacity. This article discusses whether the new cooling mechanisms in high-efficiency data centers solve the energy efficiency problem completely ...Article : texte imprimé
Ayse K. Coskun, Auteur | 2015"High performance computing (HPC) clusters run a variety of computationally intensive applications, each of which typically occupy many processors in parallel. Job allocation in HPC so far has primarily focused on performance. This article discusses how cooling awareness in job allocation can improve energy efficiency substantially." (Extrait de Circuit Cellar ...Article : texte imprimé
Ayse K. Coskun, Auteur | 2015"It is possible to design adaptive software applications that can dynamically tune themselves for meeting performance or power targets. This article demonstrates that coordinating such application tuning with other system power management methods significantly improves energy efficiency compared to solutions contained within solely application or system level." (Extrait de Circuit ...
