Auto-tuned OpenCL kernel co-execution in OmpSs for heterogeneous systems
(2019-03-01)
Article
Accés obertThe emergence of heterogeneous systems has been very notable recently. The nodes of the most powerful computers integrate several compute accelerators, like GPUs. Profiting from such node configurations is not a trivial ... -
Structural methods for the synthesis of speed-independent circuits
(1998-11)
Article
Accés obertAsynchronous circuits can be modeled as concurrent systems in which events are interpreted as signal transitions. The synthesis of concurrent systems implies the analysis of a vast state space that often requires computationally ... -
Flexible fog computing and telecom architecture for 5G networks
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Text en actes de congrés
Accés obertWe review a novel, secure, highly distributed and ultra-dense fog computing infrastructure, which can be allocated at the extreme edge of a wired/wireless network for a Telecom Operator to provide multiple unified, ... -
Towards mobile cloud computing with single sign-on access
(2017-10-30)
Article
Accés obertThe low computing power of mobile devices impedes the development of mobile applications with a heavy computing load. Mobile Cloud Computing (MCC) has emerged as the solution to this by connecting mobile devices with the ... -
GekkoFS: A temporary distributed file system for HPC applications
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Text en actes de congrés
Accés obertWe present GekkoFS, a temporary, highly-scalable burst buffer file system which has been specifically optimized for new access patterns of data-intensive High-Performance Computing (HPC) applications. The file system ... -
Runtime-assisted cache coherence deactivation in task parallel programs
(Association for Computing Machinery (ACM), 2018)
Text en actes de congrés
Accés obertWith increasing core counts, the scalability of directory-based cache coherence has become a challenging problem. To reduce the area and power needs of the directory, recent proposals reduce its size by classifying data ... -
Stencil codes on a vector length agnostic architecture
(Association for Computing Machinery (ACM), 2018)
Text en actes de congrés
Accés obertData-level parallelism is frequently ignored or underutilized. Achieved through vector/SIMD capabilities, it can provide substantial performance improvements on top of widely used techniques such as thread-level parallelism. ... -
Improving the interoperability between MPI and task-based programming models
(Association for Computing Machinery (ACM), 2018)
Text en actes de congrés
Accés obertIn this paper we propose an API to pause and resume task execution depending on external events. We leverage this generic API to improve the interoperability between MPI synchronous communication primitives and tasks. When ... -
Runtime-guided management of stacked DRAM memories in task parallel programs
(Association for Computing Machinery (ACM), 2018)
Text en actes de congrés
Accés obertStacked DRAM memories have become a reality in High-Performance Computing (HPC) architectures. These memories provide much higher bandwidth while consuming less power than traditional off-chip memories, but their limited ... -
Testing the performance of sensors for ozone pollution monitoring in a citizen science approach
(Elsevier, 2019-02-15)
Article
Accés obertTropospheric ozone (O3) is an environmental pollutant of growing concern, especially in suburban and rural areas where the density of air quality monitoring stations is not high. In this type of areas citizen science ... -
Learning from the optical spectrum: failure detection and identification [Invited]
(Institute of Electrical and Electronics Engineers (IEEE), 2018-07-23)
Article
Accés obertThe availability of coarse-resolution cost-effective Optical Spectrum Analyzers (OSA) allows its widespread deployment in operators’ networks. In this paper, we explore several machine learning approaches for soft-failure ... -
Monitoring and data analytics: Analyzing the optical spectrum for soft-failure detection and identification
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Comunicació de congrés
Accés restringit per política de l'editorialFailure detection is essential in optical networks as a result of the huge amount of traffic that optical connections support. Additionally, the cause of failure needs to be identified so failed resources can be excluded ...
