Asynch

About

Asynch is a numerical library for solving differential equations with a tree structure.

It was developed by the Iowa Flood Center (IFC) for the timelly simulation of extensive river networks in Iowa, U.S.A., a state with plain topography and bordered both by Missouri and Mississipi Rivers. It is a core component of IFC's near-realtime flood forecasting system.

Asynch is focused on parallelization for solving complex equations asynchronously in high performance computing (HPC) systems.

My contibutions

• Improved the step of data input by adding support to optimized binary files;
• Implemented multiple different differential equations to represent surface and sub-surface water flow processes;
• Preformed the deployment and maintenance of the near-realtime operational system during a little more than 1 year;
• Improving and maintaining the documentation up-to-date.

Tech stack

• C programming language;
• MPI (Message Passing Interface) standard for parallel computing;
• Automake for automated compiling.
