Meet our users: Siddhartha Mishra

The new series of portraits with selected researchers is called "Meet our users". The idea is to get more insight into our users' research and our infrastructure's role in their research.

“I wholeheartedly thank the terrific personnel at CSCS who always work hard to keep the HPC facilities running, even in very adverse circum- stances. A large part of the research of my lab cannot be performed without their dedication”. (Image: Alessandro Della Bella, CSCS)

Specialised in
Design and Analysis of algorithms for scientific simulations.

HPC means for me
The main resource to test my algorithms in different settings and to discover interesting and unexpected facets of the system being studied.

“Piz Daint” to study 3D compressible flows

We are using “Piz Daint” to compute statistical solutions for compressible fluids. These mathematical objects are probability measures in infinite dimensions that model all possible multipoint correlations of the flow and describe uncertainty propagation in turbulent fluid flows. We run an optimized, high-resoution, finite volume code (ALSVINN) on “Piz Daint” to compute statistical observables such as mean, variance, structure functions, etc., for three-dimensional compressible turbulent flow to discover interesting qualitative and quantitative properties of these solutions.
