The Scalable Analyses lab tackles computationally demanding challenges in research and industry. We cover the disciplines involved from the bare metal of computer architectures to fully automated production workflows by integrating modeling and simulation, high-performance computing, software engineering, data analytics, and verification and validation. This overarching approach is key to building visionary, portable, robust and efficient software pipelines.

	Alex Breuer leads the Scalable Data- and Compute-intensive Analyses lab. His research and teaching activities cover the full spectrum of algorithms and software for modern and emerging hardware. In 2014, Alex was honored with an ACM/IEEE-CS George Michael Memorial HPC Fellowship for his Ph.D. project “High Performance Earthquake Simulations”. In addition, he and his collaborators have been awarded with the PRACE ISC Award and nominated as ACM Gordon Bell finalists. Alex holds a doctoral degree from the Technical University of Munich.
	Shima Baniadamdizaj is a doctoral candidate in the lab. She holds a master’s degree in Artificial Intelligence and utilized deep neural networks for the localization of documents in photos taken by smartphones. Her doctoral research tackles computational challenges on Arm and OpenPOWER processors. Here, Shima harnesses low-level kernels to accelerate holistic pipelines covering modeling and simulation, and data analytics.
	Max Engel holds a Master’s degree in Computer Science from Friedrich Schiller University Jena. In his Master’s thesis, Max implemented and analyzed the numerical core of an ADER-DG finite element solver using the high-performance tensor library PyTorch. His Ph.D. research revolves around efficient algorithms and software backends for high-performance tensor contractions, with a special focus on the Einstein summation convention.
	Max Koch is a researcher in the lab and a graduate student at Karlsruhe Institute of Technology. He holds a Bachelor’s degree in Computer Science from Friedrich Schiller University Jena. In his Bachelor’s thesis, Max implemented a routine to efficiently evaluate Einstein summation expressions by utilizing small matrix multiplication kernels. Continuing his research in this field, Max now focuses on high-performance algorithms targeting the computation of tensor operations on hardware accelerators like GPUs.
	Felix Lindner holds a Master’s degree in Computer Science from University of Applied Sciences Bingen. In his Bachelor’s thesis, Felix implemented a recurrent neural network in OpenCL. For his Master’s thesis, he used GPUs to accelerate fluid dynamics simulations. His Ph.D. research focuses on tensor compilation to lower tensor contractions to different hardware. This approach is based on the einsum notation.
	Justus Dreßler is an undergraduate student at Friedrich Schiller University Jena. Justus is currently writing his Bachelor’s thesis on “Scaling Out: Distributed Memory Parallelism for Einsum Trees”. One of the main goals is to successfully scale the evaluation of einsum trees across both NUMA domains on a dual-socket NVIDIA Grace CPU Superchip system. He is also working on multi-node scaling.
	Thorsten Kröhl is a student at Friedrich Schiller University Jena, currently working on his Bachelor’s thesis “A Graphical User Interface (GUI) for the Compilation of Tensor Operations”. His research involves developing a tool to visualize and analyze tensor contractions, allowing users to explore, modify, and understand how these contractions are computed by a primitive-based backend.
	Stefan Remke is an undergrad student at Friedrich Schiller University Jena, majoring in Computer Science. Stefan optimizes high-performance computing primitives for the Arm Neoverse V2 microarchitecture. As part of his work, he is developing just-in-time code generation routines for small matrix-matrix kernels targeting NVIDIA’s Grace CPU Superchip. In addition, Stefan explores the generation of tensor processing primitives for Qualcomm’s Neural Processing Unit through the Hexagon Vector Extensions.
