PSNC (Poznan Supercomputing and Networking Center) has been working on
the exact same piece of software, called SMOA Computing, for some time
now. I've been involved in this project for some time. Major features
include:

- C implementation using gSOAP, it uses SMOA Core, our library with
standard interface for service configuration, loadable modules, and
other neat stuff.
- SMOA Core has modules for various authentication mechanisms and
authorization policies. It has an ability to accept SAML assertions as
an authentication mechanism. Besides, you may currently use plain
HTTP, SSL (with client authentication), GSI or WS-Security Username.
- DRMAA interface to job schedulers (we mostly use it with SGE and
LSF). Remote users are mapped to local uids.
- Web Service interface compliant with OGSA Basic Execution Service
Version 1.0 enchanced with our extensions.
- JSDL HPC Profile Application Extension, Version 1.0.
- HPC File Staging Profile, Version 1.0.
- HPC Basic Profile, Version 1.0.
- It's customizable with easy to write Python or C plugins. For
example, one can write a plugin that reacts to job state changes (e.g.
sends out a notification).
- Includes Advance Reservation port that allows you to reserve
resources in advance and then submit jobs within these reservations.
Supported with SGE and LSF.
- Work is currently under way to implement JSDL Parameter Sweep.
