Workstations provide an attractive platform to develop software. This paper describes the NXLib environment which enables users to use this platform to develop parallel applications. The source code compatibility of NXLib applications with Intel's Paragon multicomputer system easily allows to migrate these applications to a supercomputer. The performance… (More)
Much computational power on state-of-the-art multicomput-ers like the Paragon is wasted with porting applications. Using networks of workstations is an attempt to withdraw this workload from multicom-puter systems. Therefore an environment is needed which provides the programming interface of multicomputers on coupled workstations. The paper describes the… (More)
In this paper, we dicuss the the design and implementation of the PFSLib library wich offers the functionality of Intel's parallel file system PFS. It is intended to be used with parallel programming environments like PVM, P4, and NXLib on workstation clusters. We also present preliminary performance results of PFSLib in comparison to NFS.
