I represent the Thebes middleware consortium, which is hosted at Georgetown University.
One of the things the Thebes consortium is working on is a job acceptance service that can accept jobs, translate them to DRMAA, and submit them to job schedulers. Our intention is to include the ability to accept SAML assertions to make policy decisions.
We currently use an axis web service that takes JSDL and uses DRMAA to submit the job to Sun Grid Engine. It is rudimentary at this point.
We're interested in projects that are working in similar arenas, and we're interested in thoughts from the JSDL team about recommendations, suggestions, etc.
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. Cheers, -- Piotr Domagalski
