NHR PerfLab Seminar Series
The NHR PerfLab is a collaborative effort by the NHR centers at FAU, RWTH Aachen, ZIB Berlin, and the University of Paderborn to combine resources and activities around performance engineering, code analysis, HPC computer architectures, and tools. The NHR PerfLab seminar is a series of public talks about those topics, and more. The usual time slot is Tuesday 2 p.m. – 3 p.m CEST. If you want to get notified of upcoming talks, subscribe to the nhr-announcements mailing list.
