Dr. Markus Blatt

Entwicklung von maßgesccheiderter Simulationssoftware auf Basis von Open Source (DUNE, DUMUX, OPM, etc.). Entwickler von Open Source Software OPM/flow zur Simulation von Reservoiren, CO2 Speicherung in Reservoiren und Upscaling.

Supervising master thesis on overlapping Schwarz preconditioners on the GPU with CUDA. Published a paper that allows scientists to describe easily the parallel domain decomposition and minimize the communication effort on supercomputers. Achieved the first realistic soil infiltration simulation on a parallel supercomputer with >250000 processes. Reduced memory usage of an oil reservoir simulator by 50%.

Co-authored two papers defining a hierarchical grid interface in C++ suitable for switching the underlying implementation without a performance loss. Designed a new lecture on advanced C++ programming techniques. Initiated and partially designed a software course for scientists.

Developed an easy to use iterative solver library for parallel supercomputers. Published a paper on efficient data-structures in C++ for iterative solvers of systems of partial differential equations. Promoted to one of five lead developers of a parallel C++ software toolbox for solving partial differential equations (DUNE).

Developed JUnit test and a java package for XML file consistency tests. Evaluated the Java and Perl API of ENSEMBLE database.

Developed and implemented a three-tier architecture (Java, CORBA, JDBC, Oracle, XML) for an existing risk to market application to facilitate global collaboration. Lead a team of two developer
