Thread debugging device, thread debugging method and information storage medium

A thread debugging method for debugging at least one thread among a plurality of threads which are executed in association with each other on a computer and adapted to sequentially execute respective predetermined command sequences of threads, comprising:

• a first step of causing the computer to execute at least some processing of at least one target thread to be debugged among the plurality of threads;
• a second step of causing the computer to execute non-target threads, which are threads other than the at least one target thread among the plurality of threads, during execution of the at least one target thread by the first step while restricting advance of processing of the command sequences of the non-target threads;
• and
• when debugging a target thread, a third step of embedding a command in each non-target thread to execute processing to jump to itself, wherein
• the advance of processing of the command sequences of the non-target threads is restricted by causing the non-target threads to execute the embedded command,
• wherein the plurality of threads are respectively allocated to a plurality of processors within the computer and executed, and these threads map hardware resources in the processors to which the respective threads are allocated to an address space referred to by each thread such that the hardware resources can be referred to by each thread.

A non-transitory computer-readable recording medium having stored therein a program for debugging at least one thread among a plurality of threads which are executed in association with each other on a computer and adapted to sequentially execute respective predetermined command sequences of threads, wherein the program causes the computer to:

• execute at least some processing of at least one target thread to be debugged among the plurality of threads;
• execute non-target threads, which are threads other than the at least one target thread among the plurality of threads, during execution of the at least one target thread while restricting advance of processing of the command sequences of the non-target threads;
• and
• when debugging a target thread, embed a command in each non-target thread to execute processing to jump to itself, wherein
• the advance of processing of the command sequences of the non-target threads is restricted by causing the non-target threads to execute the embedded command,
• wherein the plurality of threads are respectively allocated to a plurality of processors within the computer and executed, and these threads map hardware resources in the processors to which the respective threads are allocated to an address space referred to by each thread such that the hardware resources can be referred to by each thread.
