- W51107697 abstract "The computer workstation, introduced by Sun Microsystems in 1982, was the tool ofchoice for scientists and engineers as an interactive computing environment for the developmentof scientific codes. However, by the mid-1990s, the performance of workstationsbegan to lag behind high-end commodity PCs. This, coupled with the disappearance ofBSD-based operating systems in workstations and the emergence of Linux as an opensourceoperating system for PCs, arguably led to the demise of the workstation as weknew it.Around the same time, computational scientists started to leverage PCs runningLinux to create a commodity-based (Beowulf) cluster that provided dedicated computecycles, i.e., supercomputing for the rest of us, as a cost-effective alternative to largesupercomputers, i.e., supercomputing for the few. However, as the cluster movementhas matured, with respect to cluster hardware and open-source software, these clustershave become much more like their large-scale supercomputing brethren — a shareddatacenter resource that resides in a machine room.Consequently, the above observations, when coupled with the ever-increasing performancegap between the PC and cluster supercomputer, provide the motivation for apersonal desktop cluster workstation — a turnkey solution that provides an interactive and parallel computing environment with the approximate form factor of a Sun SPARCstation1 “pizza box” workstation. In this paper, we present the hardware and softwarearchitecture of such a solution as well as its prowess as a developmental platform for parallel codes. In short, imagine a 12-node personal desktop cluster that achieves 14 Gflops on Linpack but sips only 150-180 watts of power, resulting in a performance-power ratio that is over 300% better than our test SMP platform." @default.
