Every node element contains 8 vector processors, which uses one single shared memory of capacity 16GB. This massive super computer brought about a high scaled performance of 40Tflops and 10TB memory capacity. The goal of the Earth Simulator project is to simulate atmospheric and oceanic phenomena on Earth. There are five research projects, each of which concentrates on a specific area of Earth research.

This document contains concurrent and parallel computing seminar work at Lappeenranta University of technology; the topic focuses on super computer technologies, specifically Earth Simulator. The Earth Simulator (ES) is a high-speed super computer technology that was started as a research project in 1997 to better understand and predict the climate change and global environment at large. The Earth simulator is a large scale super computer which encompass of 640 processor elements bonded by a single stage full crossbar network.Every node element contains 8 vector processors, which uses one single shared memory of capacity 16GB.

Natural convection heat transfer from a vertical cylinder with annular step and triangular fins has been studied numerically at various Rayleigh numbers within the laminar range. The computations were carried at constant fin spacing to tube diameter ratio of 1. In the current study, numerical simulations of Navier-Stokes equation supported with the energy equation are conducted for a vertical cylinder with annular step fins as well as triangular annular fins using the algebraic multi-grid solver of Fluent 15. With an increase in Rayleigh number, we’ve discovered a trend that the surface Nusselt number goes on increasing with comparison from a simple rectangular fin. Apart from this, the material needed for the step and triangular fins has been reduced with enhancements in the heat transfers.Keywords
