Glossary

Data-driven pages Web pages that require database access to be generated, for example, the forums, and statistics pages. The database is occasionally disabled for maintenance.

Feeder Fills up the scheduler work queue with workunits ready to be sent. The scheduler is too busy handling transaction with clients so the feeder does this job.

File deleter Deletes input/output files when no longer needed. This program keeps our upload/download disks as clean as possible.

FLOPS An acronym for FLoating point Operations Per Second. This is a measure of computing performance, the higher the number, the more calculations per second.

Scheduler Determines what work is going to be sent to/received from requesting clients. If this is down, you cannot send any results or receive any workunits.

Transitioner Handles state transitions of workunits and results. Basically, the transitioners keep track of the many, many results in progress and makes sure they properly move down the pipeline. It is always asking the questions: Is this workunit ready to send out? Has this result been received yet? Is this a valid result? Can we delete it now?

Validator Validates results returned by the clients, checkes the data integrity and then issues credit to responsible users accordingly.
