No. In fact very little bandwidth is used, most of the processing is done
The way it works is:
- Your computer calls the research project and asks if there is work to be
- One of more "tasks" are downloaded -- software and a datasets to process
- your computer's CPU processes the data, offline with no network connection
- when done, your system uploads the result data to the researchers
The data uploaded by your PC is combined with the tasks completed by
thousands of other PCs to offer supercomputer power. It is the job of the
researchers to break their work into small pieces suitable as tasks.
I am running one task now that is only 55% done even though it has been
running for three days.
