Enabling Ada and OpenMP runtimes interoperability through template-based execution
(Elsevier, 2020-05)
Article
Open AccessThe growing trend to support parallel computation to enable the performance gains of the recent hardware architectures is increasingly present in more conservative domains, such as safety-critical systems. Applications ... -
Tailwind: Fast and atomic RDMA-based replication
(USENIX Association, 2018)
Conference report
Open AccessReplication is essential for fault-tolerance. However, in in-memory systems, it is a source of high overhead. Remote direct memory access (RDMA) is attractive to create redundant copies of data, since it is low-latency and ... -

Conference report
Open AccessHPC systems and parallel applications are increasing their complexity. Therefore the possibility of easily study and project at large scale the performance of scientific applications is of paramount importance. In this ... -
On the resilience of deep learning for reduced-voltage FPGAs
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessDeep Neural Networks (DNNs) are inherently computation-intensive and also power-hungry. Hardware accelerators such as Field Programmable Gate Arrays (FPGAs) are a promising solution that can satisfy these requirements for ... -
Application-level differential checkpointing for HPC applications with dynamic datasets
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Open AccessHigh-performance computing (HPC) requires resilience techniques such as checkpointing in order to tolerate failures in supercomputers. As the number of nodes and memory in supercomputers keeps on increasing, the size of ... -
Evaluating built-in ECC of FPGA on-chip memories for the mitigation of undervolting faults
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Open AccessVoltage underscaling below the nominal level is an effective solution for improving energy efficiency in digital circuits, e.g., Field Programmable Gate Arrays (FPGAs). However, further undervolting below a safe voltage ... -

Article
Open AccessThe number of devices connected to the IoT is on the rise, reaching hundreds of billions in the next years. Many devices will implement some type of critical functionality, for instance in the medical market. Energy awareness ... -
STT-MRAM for real-time embedded systems: performance and WCET implications
(Association for Computing Machinery (ACM), 2019)
Conference report
Open AccessSTT-MRAM is an emerging non-volatile memory quickly approaching DRAM in terms of capacity, frequency and device size. Intensified efforts in STT-MRAM research by the memory manufacturers may indicate a revolution with ... -
Towards specification of a software architecture for cross-sectoral big data applications
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Open AccessThe proliferation of Big Data applications puts pressure on improving and optimizing the handling of diverse datasets across different domains. Among several challenges, major difficulties arise in data-sensitive domains ... -
Continuous-action reinforcement learning for memory allocation in virtualized servers
(Springer, 2019)
Conference report
Open AccessIn a virtualized computing server (node) with multiple Virtual Machines (VMs), it is necessary to dynamically allocate memory among the VMs. In many cases, this is done only considering the memory demand of each VM without ... -
Analysis of the key features of the seismic actions due to the three main earthquakes of May 11, 2011 in Lorca, Spain
(2019)
Article
Open AccessThe seismic records are in general valuable information, especially in cases where damage in buildings has occurred. The main purpose of the present document is to describe the principal results of the analysis of features ... -
