Prof. Dr. Roland Leißa
Juniorprofessur für Programmiersprachen und Compilerdesign
Der Fokus dieser Gruppe liegt auf der Entwicklung innovativer Programmiersprachen und Compiler, die eine Programmierung portabler und hochperformanter Anwendungen für moderne Computerarchitekturen ermöglichen. Dabei konzentrieren wir uns insbesondere auf verschiedene Formen der Parallelisierung. Gerade vor dem Hintergrund einer stetig heterogener werdenden Rechnerlandschaft sind solche Werkzeuge von außerordentlicher Bedeutung. Unsere Arbeit legt großen Wert darauf, konkrete Anwendungsprobleme aus Industrie und Forschung wie beispielsweise Simulationssoftware mit theoretisch fundierten Methoden zu abstrahieren und dadurch übergeordnete und wiederverwendbare Lösungsansätze zu schaffen.
