Abstract
Method and apparatus to enable collection of information required for solving a problem caused by simultaneous access to a shared resource in a multithreading environment. In an information processor capable of executing a routine including a tracing process of collecting information related to the processing status in multithreading, a routine being executed is registered for each thread being activated, and the level of the tracing process for the routine being executed is determined based on information in the registration. The tracing process level for the routine being executed can be determined based on whether any routine identical to, or in a predetermined relation with, the routine is already registered.References Cited

Independent Claims | See all claims (20)
- 1. An information processor suitable for executing a routine including a tracing process for collecting information related to multithreading processing status, the information processor comprising: routine registration means for registering a routine being executed for each thread being activated; and level determination means for determining a level of a tracing process for the routine being executed based on registration information registered by the routine registration means, wherein the level determination means indicates permission, in determining the level of the tracing process for the routine being executed, for unrestricted execution of a tracing process if a routine identical to, or in a predetermined relation with, the routine being executed is registered.
- 11. A tracing process method in an information processor suitable for executing a routine including a tracing process for collecting information related to multithreading processing status; the tracing process method comprising: a routine registration step for registering a routine being executed for each thread being activated; and a level determination step for determining a level of the tracing process for the routine being executed based on information included in the registrations wherein the level determination step indicates permission, in determining the level of a tracing process for the routine being executed, for unrestricted execution of the tracing process if any routine identical to, or in a predetermined relation with, the routine being executed is registered.
