Comparing the Performance of Different x86 SIMD Instruction Sets for a Medical Imaging Application on Modern Multi- and Manycore Chips
Johannes Hofmann, Jan Treibig, Georg Hager +1
Single Instruction, Multiple Data (SIMD) vectorization is a major driver of performance in current architectures, and is mandatory for achieving good performance with codes that ar…
Performance Engineering for a Medical Imaging Application on the Intel Xeon Phi Accelerator
Johannes Hofmann, Jan Treibig, Georg Hager +1
We examine the Xeon Phi, which is based on Intel's Many Integrated Cores architecture, for its suitability to run the FDK algorithm--the most commonly used algorithm to perform the…
LIKWID: Lightweight Performance Tools
Jan Treibig, Georg Hager, Gerhard Wellein
Exploiting the performance of today's microprocessors requires intimate knowledge of the microarchitecture as well as an awareness of the ever-growing complexity in thread and cach…
Leveraging shared caches for parallel temporal blocking of stencil codes on multicore processors and clusters
Markus Wittmann, Georg Hager, Jan Treibig +1
Bandwidth-starved multicore chips have become ubiquitous. It is well known that the performance of stencil codes can be improved by temporal blocking, lessening the pressure on the…
