2. Motivation

Task stealing algorithm has been enhanced by various optimization strategies. [9, 12, 13] address the issues based on profiling data which require the tools to capture it. Theses profile based strategies do not consider the topology of core and memory interconnections. In contrast to this, we propose a topological aware, non-profile and dynamic task stealing strategy. This proposed strategy is based on capturing the topology of underlying hardware which does not cause any overhead since building topology tree is one time process and that too during the initialization of the library. This optimized task stealing strategy can be directly opted into user-level run-time libraries such as Cilk[4], OpenMP and TBB[14]. To the best of our knowledge, the work proposed in the paper provides better solution for On Chip NUMA Multi Core runtime environments.
