We present a new performance model based on the roofline concept for the analysis and performance prediction of distributed computing clusters. The background for our performance modeling is the 28 km InfiniBand interconnection between two bwGRiD clu

This paper considers Java as an implementation language for a starting part of a computer algebra library. It describes a design of basic arithmetic and multivariate polynomial interfaces and classes which are then employed in advanced parallel and d

We present generic, type safe (non-unique) common divisors of solvable polynomials software. The solvable polynomial rings are defined with non-commuting variables, moreover, in case of parametric (solvable) coefficients the main variables may not co

We develop a simple hierarchical model for the performance analysis of compute clusters assembled from multi-core compute nodes connected by a (high-speed) network. The performance is described by the dimensionless speed-up and efficiency in dependen

The IPACS-Project (Integrated Performance Analysis of Computer Systems), which was founded by the German Federal Department of Education, Science, Research and Technology (BMBF), wants to define a new basis for measuring system performance of distrib

We recall definitions and properties of parametric solvable polynomial rings and variants. For recursive solvable polynomial rings, i.e. solvable polynomial rings with coefficients from a solvable polynomial ring, also commutator relations between ma

Let R be a commutative ring with 1, let R?X1,?,Xn?/I be the polynomial algebra in the n?4 noncommuting variables X1,?,Xn over R modulo the set of commutator relations I={(X1+···+Xn)?Xi=Xi?(X1+···+Xn)|1?i?n}. Furthermore, let G be an arbitrary g
