Analysis of Intel's Haswell Microarchitecture Using The ECM Model and Microbenchmarks
Johannes Hofmann, Dietmar Fey, Jan Eitzinger +2
This paper presents an in-depth analysis of Intel's Haswell microarchitecture for streaming loop kernels. Among the new features examined is the dual-ring Uncore design, Cluster-on…
Automatic Loop Kernel Analysis and Performance Modeling With Kerncraft
Julian Hammer, Georg Hager, Jan Eitzinger +1
Analytic performance models are essential for understanding the performance characteristics of loop kernels, which consume a major part of CPU cycles in computational science. Star…
Execution-Cache-Memory Performance Model: Introduction and Validation
Johannes Hofmann, Jan Eitzinger, Dietmar Fey
This report serves two purposes: To introduce and validate the Execution-Cache-Memory (ECM) performance model and to provide a thorough analysis of current Intel processor architec…
Performance analysis of the Kahan-enhanced scalar product on current multicore processors
Johannes Hofmann, Dietmar Fey, Jan Eitzinger +2
We investigate the performance characteristics of a numerically enhanced scalar product (dot) kernel loop that uses the Kahan algorithm to compensate for numerical errors, and desc…
