Massively Parallel Implementation of the Mesoscale Compressible Community Model

Massively Parallel Implementation of the Penn State/ncar Mesoscale Model

1. INTRODUCTION Parallel computing promises signiicant improvements in both the raw speed and cost performance of mesoscale atmospheric models. On distributed-memory massively parallel computers available today, the performance of a mesoscale model will exceed that of conventional supercom-puters; on the teraaops machines expected within the next ve years, performance will increase by several o...

Evaluation of two lattice Boltzmann methods for fluid flow simulation in a stirred tank

In the present study, commonly used weakly compressible lattice Boltzmann method and Guo incompressible lattice Boltzmann method have been used to simulate fluid flow in a stirred tank. For this purpose a 3D Parallel code has been developed in the framework of the lattice Boltzmann method. This program has been used for simulation of flow at different geometries such as 2D channel fluid flow an...

Mpmm: a Massively Parallel Mesoscale Model

A Real-time North American Forecast at 10km Resolution with the Canadian Mc2 Meso-lam

The next generation of high-performance computers will be based on clusters of sharedmemory symmetric multiprocessor (SMP) nodes interconnected by a low-latency, highbandwidth network. In this paper, the parallel performance of the nonhydrostatic Mesoscale Compressible Community (MC2) limited area atmospheric model on clusters of NEC SX-4 SMP nodes is presented. Several hybrid parallel programm...
