System to optimally create parallel processes and recording medium

An optimizing device to generate object code for a source program which is executed in parallel by generating a plurality of threads, comprising:

• a first parallel process creation system to create respective ones of the plurality of threads relative to repeating processes for which the source program does not include instructions for parallel processing;
• a thread management system to store, in a memory, information regarding the respective threads created;
• and
• a second parallel process creation system to create other respective ones of the plurality of threads that reference information controlled by the thread management system for the threads,
• wherein information is stored in the memory relative to the respective threads created for the processes for which parallel processing is specified.

A computer readable recording medium to implement with a computer a method of optimally creating parallel processes for a source program, the method comprising:

• generating code to create a plurality of threads relative to repeating processes for which the source program does not include instructions for parallel processing;
• storing in a memory information regarding the respective threads created;
• and
• generating code to create other threads that reference information controlled by a thread control management system for the threads,
• wherein information is stored in the memory relative to the respective threads created for the processes for which parallel processing is specified.

A device to create parallel processes for a source program, comprising:

• a first parallel process creation system to generate first parallel processes for first portions of the source program;
• a second parallel process creation system, different from the first parallel process creation system, to generate second parallel processes for second portions of the source program;
• and
• an optimizing device to optimize a generation of the first and second parallel processes with respect to the source program by using the first parallel process creation system and the second parallel process creation system.

An optimizing device, comprising:

• a thread management system to store, in a memory, information regarding a plurality of generated threads;
• a first parallel process creation system to generate a first portion of object code from a source program to create respective ones of the plurality of threads corresponding to repeating processes that are not specified as parallel in the source program;
• and
• a second parallel process creation system to generate a second portion of the object code from the source program to create other respective ones of the plurality of threads that reference information controlled by the thread management system relative to processes for which parallel processing is specified in the source program, the first and second portions of object code being executed in parallel by the plurality of threads.
