DRMAA
From Wikipedia, the free encyclopedia
DRMAA or Distributed Resource Management Application API is a high-level Global Grid Forum API specification for the submission and control of jobs to one or more Distributed Resource Management (DRM) systems within a Grid architecture. The scope of the API covered all the high level functionality required for Grid applications to consign jobs to local Grid DRM systems, and it included common operations on jobs like termination or suspension.

[edit] Development Model
The development of this API was done through the Global Grid Forum, in the model of IETF standard development, and it was originally co-authored by:
- Roger Brobst from Cadence Design Systems
- Waiman Chan from IBM
- Fritz Ferstl from Sun Microsystems
- Jeff Gardiner from John P. Robarts Research Institute
- Andreas Haas from Sun Microsystems (Co-Chair)
- Bill Nitzberg from Altair Grid Technologies
- Hrabri Rajic from Intel (Maintainer & Co-Chair)
- John Tollefsrud from Sun Microsystems Founding (Chair)
This specification was first proposed at Global Grid Forum 3 (GGF3) in Frascati, Italy, but gained most of its momentum at Global Grid Forum 4 in Toronto, Ontario. The development of the specification was first proposed with the objective to facilitate direct interfacing of applications to existing DRM systems by application's builders, portal builders, and Independent Software Vendors (ISVs). Because the API was co-authored by participants from a wide-selection of companies and included participants from industries and education, its development resulted in an open standard that received a relatively good reception from a wide audience quickly.
[edit] Significance
Without DRMAA, no standard model existed to submit jobs to component regions of a Grid, assuming each region was running local DRM systems. The first version of DRMAA API has been implemented in Sun's Grid engine and also in the University of Wisconsin-Madison's program Condor. Furthermore C, Java and IDL binding documents have been made available.
