This contribution has been added as of GT 4.0.5. In addition to the Release Notes and Admin Guide below, the following links take you to additional documentation available on the GridWay website. |
Starting with version 4.0.5, GT includes the GridWay Metascheduler, which enables large-scale, reliable and efficient sharing of computing resources (clusters , computing farms, servers, supercomputers...), managed by different LRM (Local Resource Management) systems, such as PBS, SGE, LSF, Condor..., within a single organization (enterprise grid) or scattered across several administrative domains (partner or supply-chain grid).
There exist a number of commercial and open source workload management and scheduling systems available today, each one suitable for different underlying computer infrastructures and execution profiles. GridWay stands out from other metascheduling systems because it has been specifically designed to work on top of Globus services, offering the highest functionality, quality of service and reliability on this kind of infrastructure, namely:
For project and infrastructure directors: GridWay is an open-source community project, adhering to Globus philosophy and guidelines for collaborative development.
For system integrators: GridWay is highly modular, allowing adaptation to different grid infrastructures, and supports several OGF standards.
For system managers: GridWay provides a scheduling framework similar to that found on local LRM systems, supporting resource accounting and the definition of state-of-the-art scheduling policies.
For application developers: GridWay implements the OGF standard DRMAA API (C and JAVA bindings), assuring compatibility between applications with LRM systems that implement the standard, such as SGE, Condor, Torque...etc.
For end users: GridWay provides an LRM-like CLI for submitting, monitoring, synchronizing and controlling jobs, that could be described using the OGF standard JSDL.
GridWay gives end users, application developers and managers of Globus infrastructures a scheduling functionality similar to that found on local DRM systems.
