However, in tropical regions, such as Malaysia, free cooling cannot be applied all of the time. This paper presents a strategy for grids that allows jobs to be executed on resources that are free cooled. The paper describes how a recommended period of time for using free cooled resources is predicted. The period is predicted from a historical analysis by using machine learning. Experiments on a classroom used for campus grid computing showed that, typically, free cooled resources can be used for 5 hours per day, when the temperature is less than 28 degrees Celsius. The result is of use to those developing campus grids in tropical countries. © 2012 IEEE. date: 2012 type: Conference or Workshop Item type: PeerReviewed identifier: Okitsu, J. and Naono, K. and Sulaiman, S.A. and Zakaria, N. and Oxley, A.
