Short CV

I am a postdoc at Saarland University in the group of Prof. Jan Reineke. My research interests include reverse engineering of microarchitectures, performance prediction, and security. I completed my PhD in June 2020 with a thesis entitled Automatic Generation of Models of Microarchitectures.

Tools / Websites

As part of my research, I have developed the following tools and websites.

uops.info

This website provides more than 400,000 pages with detailed latency, throughput, and port usage data for most x86 instructions on recent Intel and AMD microarchitectures. While such data is important for understanding, predicting, and optimizing the performance of software running on these microarchitectures, most of it is not documented in the official processor manuals.

Check it out at https://www.uops.info.

nanoBench

nanoBench is a Linux-based tool for running small microbenchmarks on recent Intel and AMD x86 CPUs. The microbenchmarks are evaluated using hardware performance counters. The reading of the performance counters is implemented in a way that incurs only minimal overhead.

Check it out at https://github.com/andreas-abel/nanoBench.

nanoBench Cache Analyzer

A collection of tools for analyzing undocumented cache properties using hardware performance counters.

Check it out at: https://github.com/andreas-abel/nanoBench/tree/master/tools/CacheAnalyzer.

Results are available at https://uops.info/cache.html.

MeMin

MeMin is a tool for minimizing incompletely specified Mealy machines.

Check it out here.
