In this paper, we present the work in progress that studies the run-time impact of various DTM techniques on a proposed 1024-core XMT chip. XMT aims to improve single task performance using fine-grained parallelism. Via simulations, we show that relative to a general global scheme, speedups of up to 46% with a dedicated interconnection controller and 22% with distributed control of computing clusters are possible. Our findings lead to several high level insights that can impact the design of a broader family of shared memory many-core systems.
