Selected Projects
-
PB3D
modern high performance Fortran code for analyzing peeling-ballooning stability in toroidal magnetic confinement devices. Designed for high-performance and parallel computation, supporting general 3-D plasma configurations.
-
Pylgrim
Elementary Shortest Path Problem with or without Resource Constraint (ESPPRC), for ingle source to single destination. It uses a two-fold dominance strategy allowing for negative cycles. By the knowledge of the author this was the fastest open source implementation at the time.
-
PylgrimX
Highly optimized Boost C++ implementation of pylgrim (ESPPRC). Useful for automated trading strategies for discovering arbitrage opportunities.
-
PB3D tools
HPC tools and scripts to setup, run and analyze PB3D simulations on local and remote HPC systems.
