Memory Access Characterization of OpenMP Workloads on a Multi-core NUMA Machine

Nowadays, on hierarchical shared memory multiprocessors with Non-Uniform Memory Access (NUMA), the number of cores accessing memory banks is considerably high. Such accesses produce more stress on the memory banks, generating load-balancing issues, memory contention and remote accesses. In this context, it is important to have a good understanding of memory access patterns and what are the inuences of data placement on such patterns. In this document, we have investigated memory accesses behavior of microbenchmarks and benchmarks over a ccNUMA platform with multi-core processors. Additionally, we have evaluated a set of memory policies that were used to place data among the machine memory banks. Our results have shown that an appropriate selection of data placement, considering the memory accesses, can generated great improvement gains

Etologia de Acromyrmex spp. no Planalto Serrano catarinense

Leaf cutting ants of the genus Acromyrmex are social insects found in most Brazilian agriculture systems. The continuous change in flora composition caused by intensive agricultural systems increased Acromyrmex leaf-cutting activity, causing severe damages to crops. This work was carried out in order to study the behavior of leaf-cutting ants Acromyrmex spp. in the high lands of Santa Catarina State, Brazil. The research was performed during 2007, on ant colonies located in city of Lages. The experiment was carried out during a period of 10 months. Data were collected each two hours of a day per month. The total number of leafcutting ants, the number of foraging ants in a period of one minute and the kind of foraged plant were assessed. Results showed that ant moving and foraging activity were higher during the summer season months. The highest foraging activity during the summer months was observed at night, whereas in the winter time leafcutting ants showed higher activity in the morning. Leaf-cutting ants visited a lower number of vegetable species in the winter than in the summer. The species Rumex obtusifolius was the most visited plant by Acromyrmex spp. with 90% of total foraging frequency, whereas Oxalis spp. was the less visited species.As formigas cortadeiras do gênero Acromyrmex (Formicidae) são insetos sociais presentes na maioria dos sistemas agrícolas brasileiros. A mudança na conformação florística causada pela agricultura intensiva aumentou a atividade de forrageamento deste inseto, causando prejuízos às culturas. Este trabalho teve por objetivo estudar o comportamento de Acromyrmex spp. no Planalto Serrano catarinense. O estudo foi conduzido em formigueiros localizados na Estação Experimental da EPAGRI – Lages, ao longo de 10 meses, durante ano de 2007. As avaliações foram realizadas num dia por mês, com coleta de dados a cada duas horas, por um período de 24 horas. O número total de formigas, o número de formigas forrageando no tempo de um minuto e as espécies de plantas forrageadas foram determinados. Os resultados evidenciaram que a movimentação das formigas e o forrageamento foram maiores nos meses mais quentes do ano. Nestes, o pico de forrageamento ocorreu em torno das 21 horas, ao passo que nos meses mais frios (maio e junho) as formigas concentraram o forrageamento no período da manhã. Nos meses de outono/inverno, as formigas forragearam um menor número de espécies vegetais, em comparação com outras estações do ano. Rumex obtusifolius foi a espécie vegetal mais forrageada por Acromyrmex spp., com 90% do total de visitas, enquanto que Oxalis spp foi a espécie menos forrageada

An Approach for Integrated Management of Networks with Quality of Service Support Using QAME

Providing QoS-guaranteed services in current installed networks is an important issue, but only deploying QoS services is not enough to guarantee their success: QoS management must also be provided. Nowadays, police-based network management (PBNM) addresses this need, but such management is not enough either. Network managers deal with QoS tasks that cannot be performed using only PBNM. Other solutions, besides PBNM, have to be used to proceed with QoS management-related tasks. Unfortunately, these solutions are independent from each other, leading to a scenario where integration is difficult. This paper introduces QAME (QoS-Aware Management Environment) which main goal is the provisioning of facilities to allow a common and integrated Web-based management of QoS-enabled networks

SMART: An Application Framework for Real Time Big Data Analysis on Heterogeneous Cloud Environments

International audienceThe amount of data that human activities generate poses a challenge to current computer systems. Big data processing techniques are evolving to address this challenge, with analysis increasingly being performed using cloud-based systems. Emerging services, however, require additional enhancements in order to ensure their applicability to highly dynamic and heterogeneous environments and facilitate their use by Small & Medium-sized Enterprises (SMEs). Observing this landscape in emerging computing system development, this work presents Small & Medium-sized Enterprise Data Analytic in Real Time (SMART) for addressing some of the issues in providing compute service solutions for SMEs. SMART offers a framework for efficient development of Big Data analysis services suitable to small and medium-sized organizations, considering very heterogeneous data sources, from wireless sensor networks to data warehouses, focusing on service composability for a number of domains. This paper presents the basis of this proposal and preliminary results on exploring application deployment on hybrid infrastructure

Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.
