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.
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)
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)
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.
