Description
A grid consists of high-end computational, storage, and network resources that,
while known a priori, are dynamic with respect to activity and availability.
Efficient co-scheduling of requests to use grid resources must adapt to this
dynamic environment while meeting administrative policies. We discusses
the necessary requirements of such a scheduler and introduce a distributed
framework called SPHINX that schedules complex, data intensive High Energy
Physics and Data Mining applications in a grid environment, respecting local and
global policies along with a specified level of quality of service. The SPHINX
design allows for a number of functional modules and/or distributed services to
flexibly schedule workflows representing multiple applications on grids. We
present experimental results for SPHINX that effectively utilize existing grid
middleware such as monitoring and workflow management/execution systems. These
results demonstrate that SPHINX can successfully schedule work across a large
number of grid sites that are owned by multiple units in a virtual organization.
