In this paper we present the Vienna Parallel Input Output System (ViPIOS), a novel approach to enhance the I/O performance of high performance applications. It is a client-server based tool combining capabilities found in parallel I/O runtime libraries and parallel le systems.
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 Vi-enna Parallel Input Output System (ViPIOS)  is a client-server 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)
This paper describes the speciication and implementation of PANNS (Parallel Artiicial Neural Network Sim-ulator), a general purpose tool for building, running and analyzing backpropagation neural network. This simula-tor allows arbitrary distribution of neural networks onto workstation clusters. The running system is based on the data parallel simulation… (More)
In this paper we present a novel communication layer for distributed heterogenous environments typical found in the area of Grid computing. This communication layer is used as part of ViPIOS islands, an I/O module for storage and administration of large data sets.
