An experimental study of reduced-voltage operation in modern FPGAs for neural network acceleration
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessWe empirically evaluate an undervolting technique, i.e., underscaling the circuit supply voltage below the nominal level, to improve the power-efficiency of Convolutional Neural Network (CNN) accelerators mapped to Field ... -
POSTER: SPiDRE: accelerating sparse memory access patterns
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Open AccessDevelopment in process technology has led to an exponential increase in processor speed and memory capacity. However, memory latencies have not improved as dramatically and represent a well-known problem in computer ... -
An architecture model for a distributed virtualization system
(International Academy, Research, and Industry Association (IARIA), 2018)
Conference report
Restricted access - publisher's policyThis article presents an architecture model for a Distributed Virtualization System, which could expand a virtual execution environment from a single physical machine to several nodes of a cluster. With current virtualization ... -
A toolchain to verify the parallelization of OmpSs-2 applications
(Springer, 2020)
Conference report
Open AccessProgramming models for task-based parallelization based on compile-time directives are very effective at uncovering the parallelism available in HPC applications. Despite that, the process of correctly annotating complex ... -
A novel FPGA-based high throughput accelerator for binary search trees
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Open AccessThis paper presents a deeply pipelined and massively parallel Binary Search Tree (BST) accelerator for Field Programmable Gate Arrays (FPGAs). Our design relies on the extremely parallel on-chip memory, or Block RAMs (BRAMs) ... -
Towards an auto-tuned and task-based SpMV (LASs Library)
(Springer, 2020)
Conference report
Open AccessWe present a novel approach to parallelize the SpMV kernel included in LASs (Linear Algebra routines on OmpSs) library, after a deep review and analysis of several well-known approaches. LASs is based on OmpSs, a task-based ... -
Predictive reliability and fault management in exascale systems: State of the art and perspectives
(2020-09)
Article
Open AccessPerformance and power constraints come together with Complementary Metal Oxide Semiconductor technology scaling in future Exascale systems. Technology scaling makes each individual transistor more prone to faults and, due ... -
An iris based lungs pre-diagnostic system
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Open AccessHuman lungs are essential respiratory organs. Different Obstructive Lung Diseases (OLD) such as bronchitis, asthma, lungs cancer etc. affects the respiration. Diagnosing OLD in the initial stage is better than diagnosing ... -
Exceeding conservative limits: A consolidated analysis on modern hardware margins
(2020-06)
Article
Open AccessModern large-scale computing systems (data centers, supercomputers, cloud and edge setups and high-end cyber-physical systems) employ heterogeneous architectures that consist of multicore CPUs, general-purpose many-core ... -
Aging-aware parallel execution
(Institute of Electrical and Electronics Engineers (IEEE), 2020-09-04)
Article
Open AccessComputation has been pushed to the edge to decrease latency and alleviate the computational burden of the IoT applications in the cloud. However, the increasing processing demands of Edge Applications make necessary the ... -
Asynchronous runtime with distributed manager for task-based programming models
(2020-09)
Article
Restricted access - publisher's policyParallel task-based programming models, like OpenMP, allow application developers to easily create a parallel version of their sequential codes. The standard OpenMP 4.0 introduced the possibility of describing a set of ... -
Semi-automatic validation of cycle-accurate simulation infrastructures: The case for gem5-x86
(Elsevier, 2020-11)
Article
Restricted access - publisher's policySince the early 70s, simulation infrastructures have been a keystone in computer architecture research, providing a fast and reliable way to prototype and evaluate ideas for future computing systems. There are different ...
