| Popis: | Delta Execution is a preemptive and transparent thread migration mechanism for supporting load distribution and balancing in a cluster of workstations. The design of Delta Execution allows the execution system to migrate threads of a Java application to different nodes of a cluster so as to achieve parallel execution. The approach is to break down and group the execution context of a migrating thread into sets of consecutive machine-dependent and machine-independent execution sub-contexts. Each set of machine-independent subcontexts, also known as a delta set, is then migrated to a remote node in a regulated manner for continuing the execution. Since Delta Execution is implemented at the virtual machine level, all the migration-related activities are conducted transparently with respect to the applications. No new migration-related instructions need to be added to the programs and existing applications can immediately benefit from the parallel execution capability of Delta E. |
