It is the idea of BOINC, but exactly how to split the data, exactly how to process the data, and exactly how to recombine or use the results is specific to each project. Therefore, you have to write some custom code on the server side for splitting, validation, and storing results, and some custom client code to do the processing.

But i have a doubt. My input will be a huge file and i want it to be split up into multiple parts and executed by clients. And also results of these small inputs are sent back to server. The server should assimilate all these outputs to get output for the actual input file. This is supposed to be the default functionality of BOINC application right. This functionality is provided by BOINC wrapper or should we implement in our own application?
