     12'''DRM4G''' is an open platform, based on [[http://www.gridway.org/doku.php?id=start|GridWay]] , to define, submit, and manage computational jobs. DRM4G is a Python ('''2.6+''', '''3.3+''') implementation that provides a single point of control for computing resources without installing any intermediate middlewares. As a result, a user is able to run the same job on laptops, desktops, workstations, clusters, supercomputers, and any grid.

     15=== Why DRM4G? ===
     16
     17* '''Ready-to-run''': The DRM4G bundle can be unpacked and then ran on any on any Linux OS.
     18
     19* '''Huge amount of jobs''': DRM4G is able to manage around ~200,000 jobs at the same time.
     20
     21* '''Different identities on different resources''': DRM4G handles different user accounts on various resources through a single interface.
     22
     23* '''One command''': In order to make easier to use DRM4G, there is only one command available, which is `drm4g`.
     24
     25
     26=== What is DRM4G's architecture? ===
     27
     28Infrastructure layer consists of the following components :
     29
     30* '''DRM4G CLI''' offers users commands to submit, cancel, and monitor jobs and configure resources.
     31
     32* '''!GridWay core''' is in charge of job execution and resource brokering. DRM4G takes the most of !GridWay by using its core.
     33
     34* '''DRM4G Middleware Access Driver (MAD)''' gives access to computing resources. In order to do that, there are two kind of components:
     35  * Resource Manager is responsible for collecting resource information.
     36  * Communicator provides the authentication type to access them.
     37
     38* '''DRM4G Sched''' is responsible for scheduling jobs.
