Pro ler for Use byParallel
Scheduling algorithms that use application and system knowledge have been shown to be more eeective at scheduling parallel jobs on a multiprocessor than algorithms that do not. This paper focuses on obtaining such information for use by a scheduler in a network of workstations environment. The log les from three parallel systems are examined to determine both how to categorize parallel jobs for...
متن کاملModelagem e análise de conectividade em redes sem fios obstruídas
Connectivity properties of wireless networks in open space are typically modeled using geometric random graphs and have been analyzed in depth in different studies. Such scenarios, however, do not often represent situations encountered in practice, like urban environments or indoor spaces, which are deeply affected by obstacles. As an alternative, we propose a model for obstructed wireless ad h...
متن کاملEstudo de mecanismos de segurança para proteção do roteamento em redes de sensores sem fio
Wireless Sensor Networks (WSN) are more subject to enemy action than conventional networks due to their hardware and energy constraints and due to hostile environment in which they can be inserted. This scenario is too favorable to denial of service attacks, especially in routing function, one critical function in any network. This work is focused in routing protecting in WSN. It presents a stu...
متن کاملMinimização do Impacto do Problema de Desvio de Conceito por Meio de Acoplamento em Ambiente de Aprendizado Sem Fim
Machine Learning (ML) is a research subarea of Artificial Intelligence that aims to develop computer programs that can evolve with new experiences. Among the many ML goals, the endless learning, i.e., methods that would enable computer systems to autonomously improve their own performance, based on previously learnt information, is of particular interest in the research described in this paper....
متن کاملLER Injection Line B2/B4 Study
During the PEP-II LER commissioning run in July 1998 the beam pro le in the tune up dump pro le monitor just before LER injection showed an anomalous parbolic shape. The sextupole component of the eld of bend magnets B2 and B4 in the beginning of the south injection tunnel (SIT) was thought to be the cause of this. An o -line model of the B2/B4 bend magnet eld was created using DIMAD. Results o...
