UNIFORM REGISTER FILE FOR IMPROVED RESOURCE USE

摘要

A compiler parses a multithreaded application into cohesive blocks of statements. Cohesive blocks include instructions that do not diverge or converge. Each cohesive block is associated with one or more unified registers. When a set of threads execute the instructions in a given cohesive block, each thread in the set can access the unified register independently of the other threads in the set. Accordingly, the unified register may store a single copy of data from all threads in the set of threads, thereby conserving resources.
