....A Global Layer Unix for NOW The Berkeley s Network of Workstations (popularly called NOW supercomputer) harnesses the power of clustered machines connected via high speed switched networks. It leverages commodity workstations and operating systems, and delivers performance comparable to MPPs [24]. A unified system view on NOW is provided by a software system, called GLUnix. It is built as a layer on top of existing operating systems and performs global resource allocation on a network of workstations [5] The GLUnix (Global Layer Unix) glues together individual UNIX operating systems to ....

Experience has shown that they perform many parallel tasks effectively. Network of Workstations (NOW) The Network of Workstations [AND95] concept extends the COW concept by also using idle workstation cycles even during normal working hours. This was done in response to the finding that even during daylight hours in an electrical engineering lab, over 60 of workstations are available 100 of the time. The idea of using idle ....

Introduction In recent years, clusters of workstations have become a popular platform for high performance computing [1,2]. Clusters typically use commodity networks for intra cluster communication. Performance of applications running on these clusters directly depends upon the performance of the interconnecting network.

....Such behavior results in a high rate of small data transfers between simulation nodes. Moreover, increasing the degree of parallelization in a large scale simulation generally increases the inter node communication overhead and can limit the performance of the simulation. Projects such as NOW [1] require low overhead communication to provide a network of workstations with a degree of resource sharing previously possible only on tightly coupled parallel machines.
