Parallel Programming in OpenMP
TL;DR: Aimed at the working researcher or scientific C/C++ or Fortran programmer, this text introduces the competent research programmer to a new vocabulary of idioms and techniques for parallelizing software using OpenMP.
Journal ArticleDOI
Models of thermal relaxation mechanics for particle simulation methods
TL;DR: In this paper, a comparative study of the simulation of molecular vibrational relaxation in rarefied flows by means of existing models and a novel phenomenological microscopic model is conducted; the improved technique iterates between translation-rotation and rotation-vibration exchanges; equilibrium is in this way promoted if the model for the latter process is compatible with quantized oscillators.

Lip leakage flow simulation for the gravity probe B gas spinup
TL;DR: In this paper, the lip leakage flow for the Gravity Probe B (GP-B) gas spinup system is investigated using a particle simulation code on the Connection Machine (PSiCM).
