ABSTRACT:
A method and an apparatus for managing thread private data in which the thread private data can be declared globally and which can deal with the change of the number of threads. The thread private data to be globally accessible from the multiple threads and to be managed separately by each one of the multiple threads are detected before the actual execution of the program, and a thread private data region for managing all the detected thread private data is allocated to the stack for each one of the multiple threads separately. Then, a pointer to specify a base address of the thread private data region with respect to the stack for each one of the multiple threads is registered separately, such that while executing one of the multiple threads, accesses to the thread private data are made by making accesses to the thread private data region in the stack for that one of the multiple threads according to the base address specified by the pointer registered for that one of the multiple threads.
