How does your group keep HPCE cluster busy?

Our group (CFD Laboratory) is involved in exploring various problems in the domain of fluid dynamics using computational resources. CFD simulations usually require multiple cores and huge memory resources. These simulations help in better understanding of fluid flow and also help in obtaining results which are not possible to obtain using experimental techniques. Problems involving turbulence and multiple phases require massive parallel computing to obtain results in a reasonable amount of time.

How do you see HPCE landscape in the domain of your research area change over the years?

Computational Fluid Dynamics has progressed from serial to parallel computation in the past half century. Parallel computing is the norm right now in CFD problems. Going forward there has been interest to move CFD codes on to GPUs to benefit from the massively parallel architecture. Efforts are going on to port existing CFD algorithms to GPU architectures. GPUs will help in reducing the time required to obtain solutions which will benefit problems involving turbulence and multiple phases.

What would you suggest to new faculty members and new students in your research area?

There is a growing interest in using data driven techniques to solve PDE's. This will help in building new models which can improve the computational predictions and also cut down on computational time. Another area of interest is to moving CFD algorithms to GPU architectures. Advances in HPCE will immensely help CFD researchers to obtain quicker results.
