KONWIHR project 2014
In autumn 2014, I spent two months at RRZE’s HPC optimizing the node level performance and resource utilization of our software UTBEST3D. This was funded by the “KONWIHR Multi-Core Software Initiative”. At the KONWIHR-website you can find the executive summary of this project.
A more detailed description of the conducted work is available in the corresponding report.
