Parallel Computing E191-04

  • A Research Unit of The Institute of Computer Engineering

Parallel Computing deals with the efficient utilization of parallel processing resources for the solution of computational problems. This sounds dry, but since all modern, general purpose computing devices are in some way or the other parallel computers, parallel compting is ubiquitous and inevitable.

Parallel Computing deals with the efficient utilization of parallel processing resources for the solution of computational problems. This sounds dry, but since all modern, general purpose computing devices are in some way or the other parallel computers, parallel compting is ubiquitous and inevitable.

Since not all computational problems are easily amenable to being solved in parallel, it is fascinating and challenging, and abounds with issues and problems that must be resolved better. Parallel Computing at TU Wien focuses on efficient utilization and modeling of real, existing architectures and systems (shared-memory multi-cores, distributed memory systems, hybrid and accelerated systems), on algorithms, interfaces, libraries and, to some extent, applications; and with idealized models of parallel computuations to explore the limits of parallelization.

The research area has specific expertise and interest in message-passing parallel computing, interfaces like MPI, benchmarking of parallel algorithms, scheduling, shared-memory algorithms and data structures, and parallel algorithms. All these topics are dealt with extensively in lectures offered by the research division.

The research Unit Parallel Computing is part of the Institute of Computer Engineering.
