not under its direct control. It is mostly used to talk to grid and cloud resources, like pre-WS and WS Globus, Nordugrid ARC, UNICORE and Amazon Elastic Compute Cloud. But it can also be used to talk to other batch systems, like Torque/PBS and LSF. Support for Sun Grid Engine is currently under development as part of the EGEE project. HTCondor supports the DRMAA job API. This allows DRMAA compliant clients to submit and monitor HTCondor jobs. The SAGA C++ Reference Implementation provides an HTCondor plug-in (adaptor), which makes HTCondor job submission and monitoring available via SAGA's Python and C++ APIs. Other HTCondor features include "DAGMan" which provides a mechanism to describe job dependencies.
