Development of a New Scalable Parallelization Strategy for GCM Varsha and its Historical Perspective

T Venkatesh, U Sinha
In any parallel computing experiment scalability limits the extent to which available computational resources can be used gainfully. In India, though parallel meteorological computing has been in use for over two decades, the issue of scalability has been elusive. The present paper analyses the issues impeding scalability in existing parallelization strategy and proposes alternative having superior features through asymptotic analysis of volume of communication.
