libtxsize -- a library for automated Bitcoin transaction-size estimates
Johannes Hofmann
This paper presents libtxsize, a library to estimate the size requirements of arbitrary Bitcoin transactions. To account for different use cases, the library provides estimates in…
Understanding HPC Benchmark Performance on Intel Broadwell and Cascade Lake Processors
Christie L. Alappat, Johannes Hofmann, Georg Hager +3
Hardware platforms in high performance computing are constantly getting more complex to handle even when considering multicore CPUs alone. Numerous features and configuration optio…
Bridging the Architecture Gap: Abstracting Performance-Relevant Properties of Modern Server Processors
Johannes Hofmann, Christie L. Alappat, Georg Hager +2
We describe a universal modeling approach for predicting single- and multicore runtime of steady-state loops on server processors. To this end we strictly differentiate between app…
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…
On the accuracy and usefulness of analytic energy models for contemporary multicore processors
Johannes Hofmann, Georg Hager, Dietmar Fey
This paper presents refinements to the execution-cache-memory performance model and a previously published power model for multicore processors. The combination of both enables a v…
An analysis of core- and chip-level architectural features in four generations of Intel server processors
Johannes Hofmann, Georg Hager, Gerhard Wellein +1
This paper presents a survey of architectural features among four generations of Intel server processors (Sandy Bridge, Ivy Bridge, Haswell, and Broad- well) with a focus on perfor…
