Introduction 1 Two factor8 8trongly inftuenced the re8earch in high performance computing in the la8t few year8, the 1/0 bottleneck and clu8ter 8y8tem8. Fir8tly, for many 8upercomputing application8 the limiting factor i8 not the number of available CPU8 anymore, but the bandwidth of the di8k 1/0 8y8tem. Secondly, a 8hift from the cla88ical, co8tly(More)
Due to the shift from CPU-bound to I/O bound problems the performance of the disk I/O accesses of parallel programs is a key factor for the success of solution approaches. The Vienna Parallel Input Output System (ViPIOS) [14] is a clientserver based system to speed up the disk accesses for high performance programs by combining characteristics of parallel(More)
In this paper we present the MPI-IO Interface kernel in the Vienna Parallel Input Output System (ViPIOS), which is a client-server based parallel I/O system. Compared to the already existing parallel I/O systems and libraries the concept of an independent distributed server promises to greatly enhance the usability and acceptance of the I/O system as well(More)
For applications in laser display technology, a polygonal line scanning device based on aerodynamic hemispherical bearings is being developed in our laboratory. The rotor of the device requires precise balancing for reliable performance at rotational speeds >60 000 rpm. We estimate the necessary balancing quality from basic considerations and describe, how(More)
