Component extensible parallel execution of multiple threads assembled from program components specified with partial inter-component sequence information

A computer-readable medium carrying one or more sequences of instructions for executing a plurality of program components in parallel, wherein execution of the one or more sequences of instructions by one or more processors causes the one or more processors to perform the steps of:

• defining and storing a plurality of members of a parallel execution;
• defining and storing evaluation sequence information that describes a partial order of execution of the plurality of program components;
• ordering the plurality of program components into one or more execution threads based on the evaluation sequence information;
• and
• initiating parallel execution of at least two of the execution threads with respect to two different members among the plurality of members.

An apparatus that executes a plurality of computer program components in parallel, comprising:

• one or more processors;
• one or more stored sequences of processor instructions that carry out a process of executing a plurality of program components in parallel and which, when executed by the one or more processors, cause the one or more processors to carry out the steps of:
• defining and storing a plurality of members of a parallel execution;
• defining and storing evaluation sequence information that describes a partial order of execution of the plurality of program components;
• ordering the plurality of program components into one or more execution threads based on the evaluation sequence information;
• and
• initiating parallel execution of at least two of the execution threads with respect to two different members among the plurality of members.

An apparatus that executes a plurality of computer program components in parallel, comprising:

• means for ordering the plurality of program components into one or more execution threads based on the evaluation sequence information;
• and
• means for initiating parallel execution of at least two of the execution threads with respect to two different members among the plurality of members.
