Abstract
Abstract A multi-task program debugging system comprises program converting section 13, with a multi-task program being entered, for generating a multi-task converting program 15 for collating the contents of arrayed data to be processed in parallel and, with a serial program being entered, a serial converting program 14 for saving the contents of arrayed data in the corresponding position. A collated data saving section 16 saves, when the serial converting program 14 is being executed, the contents of data into a collated data file 17 in the positions of data collation. A data collating section 18 collates, when the multi-task converting program 15 is being executed, the contents of data with the collated data file 17 in data collating positions.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
192 words
A system for debugging multi-task programs, comprising: means for converting a serial program from which a multi-task program was generated, into a converted serial program containing an instruction to save a first array of data generated prior to the execution of a parallel loop, and an instruction to save a second array of data generated after the execution of said parallel loop; means for converting said multi-task program into a converted multi-task program containing an instruction to save a third array of data generated prior to execution of a parallel loop, and an instruction to save a fourth array of data generated after execution of said parallel loop; means for executing said converted serial program, thereby to generate said first and second data arrays; means for saving at least said first and second data arrays; means for executing said converted multi-task program, thereby to generate said third and fourth data arrays; means for collating said first and third data arrays and said second and fourth data arrays, respectively; and means for generating an output indicative of a lack of identity between said first and third or said second and fourth data arrays.
Claim 2
Independent Claim
192 words
A system for debugging multi-task programs, comprising: means for converting a serial program from which a multi-task program was generated, into a converted serial program containing an instruction to save a first array of data generated prior to the execution of a parallel loop, and an instruction to save a second array of data generated after the execution of said parallel loop; means for converting said multi-task program into a converted multi-task program containing an instruction to save a third array of data generated prior to execution of a parallel loop, and an instruction to save a fourth array of data generated after execution of said parallel loop; means for executing said converted serial program, thereby to generate said first and second data arrays; means for saving at least said first and second data arrays; means for executing said converted multi-task program, thereby to generate said third and fourth data arrays; means for collating said first and third data arrays and said second and fourth data arrays, respectively; and means for generating an output indicative of a lack of identity between said first and third or said second and fourth data arrays.
Claim 3
Independent Claim
178 words
A method for debugging multi-task programs, comprising: converting a serial program from which a multi-task program was generated, into a converted serial program containing an instruction to save a first array of data generated prior to the execution of a parallel loop, and an instruction to save a second array of data generated after the execution of said parallel loop; converting said multi-task program into a converted multi-task program containing an instruction to save a third array of data generated prior to execution of a parallel loop, and an instruction to save a fourth array of data generated after execution of said parallel loop; executing said converted serial program, thereby to generate said first and second data arrays; saving at least said first and second data arrays; executing said converted multi-task program, thereby to generate said third and fourth data arrays; collating said first and third data arrays and said second and fourth data arrays, respectively; and generating an output indicative of a lack of identity between said first and third or said second and fourth data arrays.
Claim 4
Independent Claim
178 words
A method for debugging multi-task programs, comprising: converting a serial program from which a multi-task program was generated, into a converted serial program containing an instruction to save a first array of data generated prior to the execution of a parallel loop, and an instruction to save a second array of data generated after the execution of said parallel loop; converting said multi-task program into a converted multi-task program containing an instruction to save a third array of data generated prior to execution of a parallel loop, and an instruction to save a fourth array of data generated after execution of said parallel loop; executing said converted serial program, thereby to generate said first and second data arrays; saving at least said first and second data arrays; executing said converted multi-task program, thereby to generate said third and fourth data arrays; collating said first and third data arrays and said second and fourth data arrays, respectively; and generating an output indicative of a lack of identity between said first and third or said second and fourth data arrays.
