GridWay [E. Huedo, R. S. Montero and I. M. Llorente: [http://dx.doi.org/10.1002/spe.584 "A Framework for Adaptive Execution in Grids"] . Software - Practice and Experience 34 (7): 631-651, 2004] is an open source meta-scheduling technology that enables large-scale, secure, reliable and efficient sharing of computing resources (clusters, computing farms, servers, supercomputers...), managed by different DRM (Distributed Resource Management) systems, such as Sun Grid Engine, Condor, PBS, Load Sharing Facility..., within a single organization (enterprise grid) or scattered across several administrative domains (partner or supply-chain grid).

Functionality

GridWay provides end users and application developers with a scheduling framework similar to that found on local DRM systems, allowing to submit, monitor, synchronize and control jobs by means of a DRM-like command line interface (gwsubmit, gwwait, gwkill...) and DRMAA (a OGF standard).

GridWay performs job execution management and resource brokering, allowing unattended, reliable, and efficient execution of jobs, array jobs, or complex jobs on heterogeneous, dynamic and loosely-coupled Grids. GridWay performs all the job scheduling and submission steps transparently to the end user and adapts job execution to changing Grid conditions by providing fault recovery mechanisms, dynamic scheduling, migration on-request and opportunistic migration. The GridWay framework is a light component for meta-scheduling in the [http://www.globus.org/grid_software/computation/gridway.php Grid Ecosystem] intended for end users and grid application developers.

GridWay is an execution management tool for use with the Globus Toolkit. In fact, it does not require new services apart from Globus Toolkit services. Starting with Globus Toolkit 4.0.5 (released June 25, 2007), GridWay is now included by default with the Globus Toolkit distribution.
