Computational Tools
SAFL has installed its first massively parallel supercomputer at the Minnesota Supercomputing Institute. The 220-CPU machine is used to computationally study a wide range of problems, such as the blood flow in prosthetic heart valves, the hydrodynamics of aquatic locomotion, and the interaction of flow with vegetation in natural streams.
The hardware configuration of the cluster is as follows:
- 55 nodes, each node containing 2 dual-core AMD 2.2 ghz CPUs with 4GB RAM/node.
- Myrinet interconnect
The cluster will be used to conduct advanced computational fluid dynamics research in cardiovascular fluid mechanics, river hydraulics, and stream restoration. From the computational standpoint the common thread that runs through these diverse topics is that they all exhibit complex, multi-scale flow physics, which can only be accessed computationally via highly resolved numerical simulations. Using computational grids with tens of millions of grid nodes is essential in our work and this is possible only on a massively parallel computer cluster. Our computational codes have been parallelized with MPI to take full advantage of the power of the machine.
