Abstract

Optimization is a method of transforming a piece of code into another functionally equivalent piece of code to improve code quality and efficiency. The two most important characteristics are the speed and size of the code. Other characteristics include: energy required and the time it takes to compile the code. This paper uses source code (jacobi2d.c) to provide solutions by optimization of the 2-Dimentional heat conductivity problem on grid machine using C++ compiler and OpenMP (Open Multi-Processing). The paper discuss the benefits of parallel grid computing. The grid server on which this paper used has 10 computers, grid-01 to grid-08 have 2 cores and 2 Gigabytes memory while 09 and 10 have 8 cores and 8 Gigabytes memory. The process of solving rectangular 2-dimensional heat conductivity problem to optimized performance is done in number of steps from step 1 to step 4, optimization starts in step 3 and ends in step 4. In step 4, performance speedup of step 3 is compared with performance speedup of step 4 and optimal (result) performance is achieved in step 4. It is concluded that performance is optimized with parallel processing using grid machine with performance level -3 and large problem size.
