Chirp is a lightweight I/O protocol and filesystem for grid computing.
HTCondor has an internal implementation of the Chirp protocol, which allows batch jobs to access their home storage while executing on a remote machine. If a HTCondor job is submitted with +WantIOProxy=True in its submit file, then HTCondor provides a proxy at the execution site that accepts the Chirp protocol and provides access to the submitter's storage. Users can invoke the condor_chirp command at runtime to load and store files, as well as update the job's classad.
