The improvements in disk speeds have not kept up with improvements in processor and memory speeds. Conventional storage techniques, in the face of multimedia data, are inefficient and/or inadequate. Here, an efficient multimedia object allocation strategy is presented. We describe a multimedia object model, the object and storage device characteristics, and the fragmentation strategy. A bipartite graph approach is used for mapping fragments to storage devices and a cost function is used to determine an efficient allocation of an object and to balance the loads on the devices.

The emergence of high speed networks and the proliferation of high performance workstations have attracted a lot of interest in workstation-based distributed computing. Current trend in local area networks is toward higher communication bandwidth as we progress from Ethernet networks that operate at 10 Mbit/sec to higher speed networks that can operate in Gbit/sec range. Also, current workstations are capable of delivering tens and hundreds of Megaflops of computing power. By using a cluster of such high-performance workstations and the high-speed networks, a high-performance distributed computing environment could be built in cost-effective manner as an alternative of supercomputing platform. However, …

The proliferation of high performance workstations and the emergence of high speed networks have attracted a lot of interest in workstation-based supercomputing. We project that workstation-based environments with supercomputing capabilities will be available in the not-so-distant future. However a number of hardware and software issues have to be resolved before the full potential of these workstation-based supercomputing environments can be exploited. The presented research has two main objectives: (1) to investigate the limitations of communications techniques used in current workstation-based systems and to identify a set of requirements that must be satisfied to achieve workstation-based supercomputing; (2) to use these …
