A user submits a job to IBM IBM Tivoli Workload Scheduler for Virtualized Data LoadLeveler and the scheduler attempts to find resources Centers V8.2 interacts with IBM Grid Toolbox so that jobs within the cluster to satisfy the requirements of the job. can run remotely on a set of machines managed by a job ′ At the same time, IBM LoadLeveler s objective is to help scheduling system using a set of Web Services maximize the efficiency of the cluster. It attempts to do Description Language (WSDL)/Open Grid Services this by maximizing the utilization of resources, while at Infrastructure (OGSI) client interfaces for submitting, the same time helping minimize the job turnaround time monitoring, and terminating a job. OGSA is an open experienced by users. standard managed by the Global Grid Forum (GGF) IBM LoadLeveler can: standards body. Its objective is to define open interfaces and protocols for managing grids of diverse resources. • Support three different scheduling algorithms (native, The OGSA platform defines the core set of interfaces, backfill, and gang) with preemption rules. Note: Gang behaviors, and bindings that address the functions is AIX only and preemption is AIX only. relevant to application scenarios in grid environments. • Provide a set of APIs so that other scheduling algorithms can be used.
