ABSTRACT:
Systems and methods are provided for accessing thread private data in a computer. In one embodiment, a method is provided for accessing thread private data in a computer for a program executed by using a plurality of threads, wherein each of the plurality of threads may be associated with a different area of its respective stack for storage of thread private data. Further, the stacks of threads may cover a coherent address space in a memory of the computer, starting at a base address. The method may include determining a thread identifier of the one of the plurality of threads based on the base address and a stack pointer of one of the plurality of threads. In addition, the method may include accessing thread private data of one of the stacks based on the determined thread identifier.
