The efficient, convenient, and robust execution of data-driven workflows and enhanced data management are essential for productivity in scientific computing. In HPC, the concerns of storage and computing are traditionally separated and optimised... see more

In the paper, we review a suboptimal methodology of mapping of a task information graph on the architecture of a reconfigurable computer system. Using performance reduction methods, we can solve computational problems which need hardware costs e... see more

We propose several improvements to the execution-cache-memory (ECM) model, an analytic performance model for predicting single- and multicore runtime of steady-state loops on server processors. The model is made more general by strictly differentiating be... see more

High-level programming languages that allow to express numerical methods and generate efficient parallel implementations are of key importance for the productivity of domain-scientists. The diversity and complexity of hardware architectures is imposing a ... see more
