RADIC: un middleware de tolerancia a fallos que preserva el rendimiento

La tolerancia a fallos es una línea de investigación que ha adquirido una importancia relevante con el aumento de la capacidad de cómputo de los súper-computadores actuales. Esto es debido a que con el aumento del poder de procesamiento viene un aumento en la cantidad de componentes que trae consigo una mayor cantidad de fallos. Las estrategias de tolerancia a fallos actuales en su mayoría son centralizadas y estas no escalan cuando se utiliza una gran cantidad de procesos, dado que se requiere sincronización entre todos ellos para realizar las tareas de tolerancia a fallos. Además la necesidad de mantener las prestaciones en programas paralelos es crucial, tanto en presencia como en ausencia de fallos. Teniendo en cuenta lo citado, este trabajo se ha centrado en una arquitectura tolerante a fallos descentralizada (RADIC – Redundant Array of Distributed and Independant Controllers) que busca mantener las prestaciones iniciales y garantizar la menor sobrecarga posible para reconfigurar el sistema en caso de fallos. La implementación de esta arquitectura se ha llevado a cabo en la librería de paso de mensajes denominada Open MPI, la misma es actualmente una de las más utilizadas en el mundo científico para la ejecución de programas paralelos que utilizan una plataforma de paso de mensajes. Las pruebas iniciales demuestran que el sistema introduce mínima sobrecarga para llevar a cabo las tareas correspondientes a la tolerancia a fallos. MPI es un estándar por defecto fail-stop, y en determinadas implementaciones que añaden cierto nivel de tolerancia, las estrategias más utilizadas son coordinadas. En RADIC cuando ocurre un fallo el proceso se recupera en otro nodo volviendo a un estado anterior que ha sido almacenado previamente mediante la utilización de checkpoints no coordinados y la relectura de mensajes desde el log de eventos. Durante la recuperación, las comunicaciones con el proceso en cuestión deben ser retrasadas y redirigidas hacia la nueva ubicación del proceso. Restaurar procesos en un lugar donde ya existen procesos sobrecarga la ejecución disminuyendo las prestaciones, por lo cual en este trabajo se propone la utilización de nodos spare para la recuperar en ellos a los procesos que fallan, evitando de esta forma la sobrecarga en nodos que ya tienen trabajo. En este trabajo se muestra un diseño propuesto para gestionar de un modo automático y descentralizado la recuperación en nodos spare en un entorno Open MPI y se presenta un análisis del impacto en las prestaciones que tiene este diseño. Resultados iniciales muestran una degradación significativa cuando a lo largo de la ejecución ocurren varios fallos y no se utilizan spares y sin embargo utilizándolos se restablece la configuración inicial y se mantienen las prestaciones.

Breast and cervical cancer screening programme implementation in 16 countries.

OBJECTIVES: There is a continuing need to monitor and evaluate the impact of organized screening programmes on cancer incidence and mortality. We report results from a programme assessment conducted within the International Cancer Screening Network (ICSN) to understand the characteristics of cervical screening programmes within countries that have established population-based breast cancer screening programmes. METHODS: In 2007-2008, we asked 26 ICSN country representatives to complete a web-based survey that included questions on breast and cervical cancer screening programmes. We summarized information from 16 countries with both types of organized programmes. RESULTS: In 63% of these countries, the organization of the cervical cancer screening programme was similar to that of the breast cancer screening programme in the same country. There were differences in programme characteristics, including year established (1962-2003 cervical; 1986-2002 breast) and ages covered (15-70+ cervical; 40-75+ breast). Adoption of new screening technologies was evident (44% liquid-based Pap tests; 13% human papillomavirus (HPV)-triage tests cervical; 56% digital mammography breast). There was wide variation in participation rates for both programme types (<4-80% cervical; 12-88% breast), and participation rates tended to be higher for cervical (70-80%) than for breast (60-70%) cancer screening programmes. Eleven ICSN member countries had approved the HPV vaccine and five more were considering its use in their organized programmes. CONCLUSION: Overall, there were similarities and differences in the organization of breast and cervical cancer screening programmes among ICSN countries. This assessment can assist established and new screening programmes in understanding the organization and structure of cancer screening programmes.

Equality Impact Assessments - Oral Health Strategy - General Dental Services - May 2001 (PDF 72KB)

In 1998, a new law came into force in Northern Ireland – the Northern Ireland Act 1998. Section 75 of the Act places a legal obligation on each public authority to have due regard to the need to promote equality of opportunity: • between persons of different religious belief, political opinion, racial group, age, marital status or sexual orientation; • between men and women generally; • between persons with a disability and persons without; and • between persons with dependants and persons without. åÊ

A Strategy for Nursing Midwifery and Health Visiting in NI (PDF 180KB)

This study was designed to examine critically the impact of a government-led policy document upon community nursing, midwifery and health visiting practice in Northern Ireland (Strategy for Nursing, Midwifery and Health Visiting in Northern Ireland. Action Plan for Community Nurses, Midwives and Health Visitors, Working Together: A Focus on Health and Social Well-being, DHSS, 1996). The total number of participants was (n=409) and the eleven Health and Personal Social Services Trusts in NI were represented in the sample group which consisted of 93% females and 7% males. A questionnaire containing twenty items was designed and a pilot study was carried out with twenty-five community practitioners. Following the pilot study appropriate modifications were made to the questionnaire. åÊ

Breastfeeding Strategy for Northern Ireland (PDF 212 KB)

Northern Ireland has one of the lowest breastfeeding rates in the world. Low breastfeeding rates are associated with considerable morbidity, some mortality and increased health service costs for women and children. In Northern Ireland, several factors make the initiation and maintenance of breastfeeding particularly difficult; these include cultural attitudes, commercial promotion of artificial milks and obstacles for the working mother. The aim of the Strategy is to promote and support breastfeeding. Medium-term objectives: - province-wide co-ordination of breastfeeding promotional activities - commissioning of breastfeeding support within the health service - detailed and uniform collection of infant feeding statistics - research into effective means of breastfeeding promotion - improved training in lactation management for health professionals - supporting breast milk feeding for special needs infants - raising of public awareness of the importance of breastfeeding - cessation of artificial milk promotion within the health service åÊ Long-term objectives: - adopt the recommendations following review of the milk token scheme in England - bringing the marketing of infant foods and feeding products into line with the International Code of Marketing of Breast Milk Substitutes åÊ Progress will be monitored by the Northern Ireland Breastfeeding Strategy Group. åÊ åÊ

Strategy for Reducing Alcohol Related Harm (PDF 1044KB)

Alcohol, used responsibly and in moderation, is a normal and enjoyable aspect of everyday life for most people. Everyone is familiar with the wide variety of social settings in which it is consumed, ranging from casual enjoyment or relaxation to celebratory and ceremonial occasions. This widespread use of alcohol means that the manufacture and retailing of alcohol products, and its distribution through bars, clubs, restaurants and off-licences involves an estimated 32,000 jobs, both full and part time. The economic significance of this to society here is obvious. åÊ

Drug Strategy for Northern Ireland (PDF 669 KB)

This document sets out the new Strategy for addressing drug misuse problems in Northern Ireland. With a vision for all who work towards addressing this problem, four main aims are identified along with a set of outcomes. The Strategy has a minimum lifespan of five years with a first major review after three years. Since its publication the NIO is no longer responsible for the drug strategy - this work has been taken over by the Department of Health, Social Services and Public Safety.
