ECM modeling and performance tuning of SpMV and Lattice QCD on A64FX
Christie Alappat, Nils Meyer, Jan Laukemann +4
The A64FX CPU is arguably the most powerful Arm-based processor design to date. Although it is a traditional cache-based multicore processor, its peak performance and memory bandwi…

Automatic Throughput and Critical Path Analysis of x86 and ARM Assembly Kernels
Jan Laukemann, Julian Hammer, Georg Hager +1
Useful models of loop kernel runtimes on out-of-order architectures require an analysis of the in-core performance behavior of instructions and their dependencies. While an instruc…

Automated Instruction Stream Throughput Prediction for Intel and AMD Microarchitectures
Jan Laukemann, Julian Hammer, Johannes Hofmann +2
An accurate prediction of scheduling and execution of instruction streams is a necessary prerequisite for predicting the in-core performance behavior of throughput-bound loop kerne…
