Apparatus and methods for sequentially scheduling a plurality of commands in a processing environment which executes commands concurrently

摘要

A data processing system and method for scheduling a sequential execution of multiple commands. The data processing system includes an environment which executes the commands concurrently. Execution of the plurality of commands is scheduled in the environment so that the commands execute sequentially in programming order. When the commands are scheduled, a first one of the commands in the order begins and completes executing prior to a second one of the commands in the order beginning executing. When scheduled, the commands execute in the environment sequentially in programming order. In order to execute the commands sequentially, a process is spawned within which to execute the command. The execution status of the process is checked periodically by checking a process table. When the process has completed executing, a new process is spawned within which to execute the next command in the sequential order.
