Summary

In the D{O} experiment, the software filter operates in a processor farm with each node processing a single event. Processing is data-driven: the filter does local processing to verify the candidates from the hardware trigger. The filter code consists of independent pieces called ``tools``; processing for a given hardware bit is a ``script`` invoking one or more ``tools`` sequentially. An offline simulator drives the same code with the same configuration files, running on real or simulated data. Online tests use farm nodes parasiting on the data stream. We discuss the performance of the system and how we attempt to verify its correctness.
