System area networks have been developed to address the needs of computing clusters. Myricom's Myrinet architecture is one of the predominant technologies in this area. One of the key issues for SANs is fault-tolerant routing. Myrinet provides Mapper software to discover and maintain network topology. Myrinet's Mapper is centralized, susceptible to probe(More)
Fault management in high performance cluster networks has been focused on the notion of hard faults (i.e., link or node failures). Network degradations that negatively impact performance but do not result in failures often go unnoticed. In this paper, we classify such degradations as soft faults. In addition, we identify consistent performance as an(More)
— The acceleration in computational scale to solve problems in emerging " computational " fields from Nanoscience and Genetics to Astrophysics places increasingly heavy compute and data storage burdens on locally and globally distributed computer systems. We are focusing on the management of these loosely coupled systems (clusters and Grids) which are asked(More)
In this paper, we are introducing a new view for the applications and the activities using QR codes to access the information for the objects existing in everyday human environment. This view emphasizes the possibility of the QR codes as an Analog Portal—an ambient media gate to the Digital World, because it shows the new way of access to the Internet and(More)
