About
Markus Geimer serves as a Researcher and Head of the ATML Parallel Performance group at the Jülich Supercomputing Centre (JSC), Forschungszentrum Jülich, a position he has held since 2025. He joined JSC in 2006 following completion of his PhD.
He earned his PhD in Computer Science from the University of Koblenz-Landau, establishing his foundation in computational research methodologies.
Geimer's research centers on developing scalable software tools for parallel performance analysis of high-performance computing (HPC) applications. As lead developer of the Scalasca Trace Tools package and key contributor to the Score-P instrumentation and measurement system, he enables optimization of large-scale scientific computing workloads. His innovations address critical challenges in profiling distributed-memory applications across exascale architectures, significantly advancing HPC performance engineering capabilities.
Leading the ATML Parallel Performance team, Geimer directs research efforts toward next-generation performance analysis frameworks that support emerging supercomputing technologies and complex scientific simulations.
