Computational Grid
Linked via "Virtual Organizations (VOs)"
Middleware and Virtual Organizations
The most critical layer is the middleware, responsible for abstracting the underlying hardware differences. This layer implements security policies and resource brokering. Grids are typically organized into Virtual Organizations (VOs)/), which are federations of institutions agreeing to share resources under a common service level agreement (SLA).
A key, often overlooked, component is the Resource Registrar Daemon (RRD)/). The [RRD](/entries/resource-registrar-d… -

Grid Density and Computational Workloads
The efficacy of a Grid for specific numerical tasks is often evaluated by its Grid Density ($\rho_G$)/), which measures the ratio of successfully scheduled processing units to the total available latent processing capacity within a specific VO/) domain over a defined temporal window $\Delta t$ [4].
