Parallel I/O Characterisation Based on Server-Side Performance Counters

Autor: Dirk Pleiter, Salem El Sayed, Matthias Bolten, Wolfgang Frings

Publikováno v: PDSW-DISCS@SC

Provisioning of high I/O capabilities for high-end HPC architectures is generally considered a challenge. A good understanding of the characteristics of the utilisation of modern I/O systems can help address the increasing performance gap between I/O

Functional magnetic resonance imaging in real time (FIRE): Sliding-window correlation analysis and reference-vector optimization

Autor: Stefan Schor, Stefan Posse, Dieter Suter, Daniel Gembris, John G. Taylor, Wolfgang Frings

Publikováno v: Magnetic Resonance in Medicine. 43:259-268

New algorithms for correlation analysis are presented that allow the mapping of brain activity from functional MRI (fMRI) data in real time during the ongoing scan. They combine the computation of the correlation coefficients between measured fMRI ti
