Abstract
In one embodiment, the present invention includes a method for accessing registers associated with a first thread while executing a second thread. In one such embodiment a method may include preventing an instruction of a first thread that is to access a source operand from a register file of a second thread from executing if a synchronization indicator associated with the source operand indicates incompletion of a producer operation of the second thread, and executing the instruction if the synchronization indicator indicates completion of the producer operation of the second thread. Other embodiments are described and claimed.
