What is Code Porting

Chapter 9
Handbook of Research on Computational Science and Engineering: Theory and Practice
Usually a software/code is developed with a specific computational environment in mind. Therefore when a code written in one computational environment is going to be run in another computational environment, some part of the code has to be modified. The activity to make a code that runs on one machine usable in the other machine is called code porting.

Abstract
The computational architecture of Enabling Grids for E-sciencE is introduced as it made our code porting very challenging, and the discussion presented is directly applicable to EGEE users. The final solution to the code poring problem is proposed, and its performance is examined. The solution to this problem be generally faced in the other large scale computation and so is applicable to users of other HPC facilities. This chapter gives a hint to those who have difficulties in applications with heavy data Input/Output (I/O) under the computational environment whose weak point is the data I/O.
