BSC - Barcelona Supercomputing Center
Early in 2004 the Ministry of Education and Science (Spanish Government), Generalitat de Catalunya (local Catalan Government) and Technical University of Catalonia (UPC) took the initiative of creating a National Supercomputing Center in Barcelona. BSC-CNS (Barcelona Supercomputing Center – Centro Nacional de Supercomputación) is the National Supercomputing Facility in Spain and was officially constituted in April 2005. BSC-CNS manages MareNostrum, one of the most powerful supercomputers in Europe, located at the Torre Girona chapel. The mission of BSC-CNS is to investigate, develop and manage information technology in order to facilitate scientific progress. With this aim, special dedication has been taken to areas such as Computer Sciences, Life Sciences, Earth Sciences and Computational Applications in Science and Engineering.

Selective synthesis of 4-hydroxyisophorone and 4-ketoisophorone by fungal peroxygenases
(Royal Society of Chemistry, 2019-02-26)
Article
Open AccessThe recently discovered unspecific peroxygenases (UPOs) from the ascomycetes Chaetomium globosum and Humicola insolens were capable of selectively hydroxylating isophorone to 4-hydroxyisophorone (4HIP) and 4-ketoisophorone ... -
TCP Proactive Congestion Control for East–West Trffic: the Marking Threshold
(2019)
Working paper
Open AccessVarious extensions of TCP/IP have been proposed to reduce network latency; examples include Explicit Congestion Notification (ECN), Data Center TCP (DCTCP) and several proposals for Active Queue Management (AQM). Combining ... -
TensorFlow on state-of-the-art HPC clusters: a machine learning use case
(2019)
Conference lecture
Open AccessThe recent rapid growth of the data-flow programming paradigm enabled the development of specific architectures, e.g., for machine learning. The most known example is the Tensor Processing Unit (TPU) by Google. Standard ... -

External research report
Open AccessThe landscape of High Performance Computing (HPC) system architectures keeps expanding with new technologies and increased complexity. With the goal of improving the efficiency of next-generation large HPC systems, ... -
Interactions between the atmosphere, cryosphere, and ecosystems at northern high latitudes
(European Geosciences Union (EGU), 2019-02-14)
Article
Open AccessThe Nordic Centre of Excellence CRAICC (Cryosphere–Atmosphere Interactions in a Changing Arctic Climate), funded by NordForsk in the years 2011–2016, is the largest joint Nordic research and innovation initiative to date, ... -
On the Resilience of RTL NN Accelerators: Fault Characterization and Mitigation
(IEEE, 2019-02-21)
Conference lecture
Open AccessMachine Learning (ML) is making a strong resurgence in tune with the massive generation of unstructured data which in turn requires massive computational resources. Due to the inherently compute and power-intensive structure ... -
A Demo of FPGA Aggressive Voltage Downscaling: Power and Reliability Tradeoffs
(IEEE, 2018-12-06)
Conference lecture
Open AccessThe power consumption of digital circuits, e.g., Field Programmable Gate Arrays (FPGAs), is directly related to their operating supply voltages. On the other hand, usually, chip vendors introduce a conservative voltage ... -
Fault Characterization Through FPGA Undervolting
(IEEE, 2018-12-06)
Conference lecture
Open AccessThe power and energy efficiency of Field Programmable Gate Arrays (FPGAs) are estimated to be up to 20X less than Application Specific Integrated Circuits (ASICs). What is needed to close this gap is aggressive power/energy ... -
Comprehensive Evaluation of Supply Voltage Underscaling in FPGA on-Chip Memories
(IEEE, 2018-12-13)
Conference lecture
Open AccessIn this work, we evaluate aggressive undervolting, i.e., voltage scaling below the nominal level to reduce the energy consumption of Field Programmable Gate Arrays (FPGAs). Usually, voltage guardbands are added by chip ... -
On the Applicability of PEBS based Online Memory Access Tracking for Heterogeneous Memory Management at Scale
(Association for Computing Machinery (ACM), 2018-11)
Conference lecture
Open AccessOperating systems have historically had to manage only a single type of memory device. The imminent availability of heterogeneous memory devices based on emerging memory technologies confronts the classic single memory ... -
The match between climate services demands and Earth System Models supplies
(Elsevier, 2018-12)
Article
Open AccessEarth System Models (ESM) are key ingredients of many of the climate services that are currently being developed and delivered. However, ESMs have more applications than the provision of climate services, and similarly ... -
Multi-tenant Pub/Sub Processing for Real-Time Data Streams
(Springer, 2018-12)
Conference lecture
Open AccessDevices and sensors generate streams of data across a diversity of locations and protocols. That data usually reaches a central platform that is used to store and process the streams. Processing can be done in real time, ...
