1. A method of profiling and selecting grid resources for a computer program to adapt the program to use a specified grid based system of computer services via a grid adapter, the method comprising: using a profiler to generate a configuration file of the computer program, the profiler comprising a wrapper and a profiling tool, the wrapper being inserted between the computer program and a virtual machine and providing the computer program with pass-through access to the virtual machine, including using the profiling tool to execute the computer program in a testing environment; the wrapper monitoring operation of the computer program for a period of time, and monitoring and recording specified usage characteristics and patterns of the operation of the computer program to understand the use of grid capable resources that the computer program could utilize and to be cognizant of the way the computer program makes use of resources; the profiling tool building the configuration file for the computer program to select resources from the grid based system of computer services via the grid adapter, said configuration file describing a relative priority of the computer program to the grid adapter; and using said configuration file for selecting resources for the computer program from the grid based system of computer services.
