Abstract: With the popularity of multi-core processors, full use of multi core PC's performance, computer technology is increasingly to multi-core architecture and multi-core computing technology development, To improve the small Hunan 100m X 100m grid interpolation rate of temperature, using the OpenMP standard for shared memory based parallel programming model to achieve the kriging interpolation algorithm based on OpenMP. Different multi-core PC, using a small grid 100m X 100m and 500m X 500m grid terrain data for a small average temperature for interpolation, not only effectively reduce the time and interpolation algorithms to improve the speedup, and significantly integrated into business systems enhance the system's response time and performance.

Key words: Multi-core computing, OpenMP model, Kriging interpolation, Small grid interpolation
