APPARATUS FOR TASK DISTRIBUTION METHOD AND METHOD OF TRANSACTION AT A TASK THREAD GROUP UNIT ON THE DISTRIBUTED PARALLEL PROCESSING SYSTEM

摘要

A device for distributing a task per a task thread group in a distributed parallel processing system, a method thereof and a processing method thereof are provided to allocate a map task per a task thread group and share an intermediate result file about an individual map task, thereby reducing the number of reduce task transfer files. A thread unit task distributing device comprises a work manager(521) and a map task launcher(531). The work manager distributes works requested by a user by a core unit task of a separated node processor. The task launcher processes the task by a thread unit of the core in parallel. The task launcher generates an integrated intermediate result file.
