ROOM:601/603

ABSTRACT:
The popularization of the Graphics Processing Unit (GPU), found in most modern desktop computers, has brought the age of supercomputing into the hands of average scientists. Using the highly parallel architecture the GPU we have been developing code that will allow us to probe the interesting quantum behavior of ultra cold atomic gases, generally less than a few hundred micro Kelvin. The project involves two separate codes, one that utilizes the Direct Simulation Monte Carlo technique, to simulate the quantum losses experienced as an atomic gas is evaporatively cooled in a magnetic trap. The other is a Finite Element code, taking advantage of the Discrete Variable Representation (DVR) to perform full three dimensional simulations of the evolution the gas after it has undergone a quantum phase transition. We are able to deploy these codes on the local GPU supercluster, MASSIVE, to gain excellent performance.
