With the rapid growth in computing and communications technology, the past decade has witnessed a proliferation of powerful parallel and distributed systems and an ever increasing demand for practice of high performance computing and communications (HPCC). HPCC has moved into the mainstream of computing and has become a key technology in determining future research and development activities in many...
Summary form only given.This paper is talking about compute clusters , grid and cloud infrastructures with examples of Distributed European infrastructure for Supercomputing applications and Partnership for Advanced Computing in Europe(PRACE). The paper also describes DEISA system architecture,service layers, UNICORE access infrastructure, the distributed user management , production environment,...
Summary form only given. The paper discuss the impact of clouds and grid technology on HPCC using examples from a variety of fields especially the life sciences. It covers the impact of the growing importance of data analysis and note that it is more suitable for these modern architectures than the large simulations (particle dynamics and partial differential equation solution) that are mainstream...
On chip multiprocessors (CMPs) platforms, multiple co-scheduled applications can severely degrade performance and quality of service (QoS) when they contend for last-level cache (LLC) resources. Whether an application will impose destructive interference on co-scheduled applications is largely dependent on its own inherent cache access behavior characteristics. In this work, we first present case...
High Performance Computational Clusters are, in general, rather rigid objects that present to their user a limited number of degrees of freedom related, usually, only to the specification of the resources requested and to the selection of specific applications and libraries. While in standard production environments this is reasonable and actually desirable, it can become an hindrance when one needs...
