The talk would be held by Thomas Gruber, Erlangen National High Performance Computing Center Software & Tools Division, Friedrich-Alexander-University of Erlangen-Nuremberg(FAU).
LIKWID stands for “Like I Knew What I’m Doing.” It is an easy to use yet powerful command line performance tool suite for the GNU/Linux operating system. While the focus of LIKWID is on x86 processors, some of the tools are portable and not limited to any specific architecture. For the upcoming release, LIKWID has been ported to ARMv7/v8 and POWER8/9 architectures as well as for Nvidia GPU co-processors.
The LIKWID tools are used world-wide for teaching purposes or in production environments like NERSC at Lawrence Berkeley National Labratory, CSCS (Swiss National Supercomputing Center) in Lugano, the National Super Computer Center in Guangzhou, the Vienna Scientific Cluster (VSC) or the Barcelona Supercomputing Center (BSC). Moreover, LIKWID is used by the Gauss Center for Supercomputing, LRZ (Garching), HLRS (Stuttgart) and JSC (Jülich) as well as the IT provider for the Max Planck Society (MPCDF). Some of the Tier2/3 HPC centers in Germany using LIKWID are RWTH Aachen, TU Dresden, KIT Karlsruhe, University of Paderborn, University of Konstanz, University of Gießen, and the national research center DESY in Hamburg. Dr. Hatem Ltaief from Extreme Computing Research Center (KAUST) says “LIKWID rocks!”. We thank the LANL HPC ENV team to test and use LIKWID on the Darwin cluster(*).
