• Gatekeeping Policy. The Gatekeeper Server provides a Gatekeeping Service along with an
Account Validation Service. These services provide the mechanism for HPSS to
communicate information though a well-definedinterface to a policy software modulethat
can be completely written by a site. The site policy code is placed in well-defined shared
libraries for the gatekeeping policy and the accounting policy (/opt/hpss/lib/
libgksite.[a|so] and /opt/hpss/lib/libacctsite.[a|so] respectively) which are linked to the
Gatekeeper Server. The Gatekeeping policy shared library contains a default policy which
does NO gatekeeping. Sites will need to enhance this library to implement local policy
rules if they wish to monitor and load-balance requests.
