1. The outer level parallelization is adopted from the MPI approach: workloads from zones are explicitly distributed among the outer-level threads. The difference is that OpenMP now works on the shared data space as opposed to private data in the MPI version. The load balancing is done statically through the same bin-packing algorithm where zones are first sorted by size, then assigned to the least loaded thread one by one. The routine “map_zones” returns the number and list of zones (num_proc_zones and proc_zone_id) assigned to a given thread (myid) as well as the number of threads (nthreads) for the inner parallel regions.

Another potential way to reduce overhead associated with nested parallel regions is by predefining a thread tree structure as proposed in [1] and [13] so that the runtime can perform better scheduling optimization. The approach based on the Subteam extension to OpenMP overcame some of the limitations with nested OpenMP and showed promise in achieving performance close to that of the hybrid MPI+OpenMP method. Our study also points out the importance of extending the Subteam proposal to include API for subteam creation and management.

Beyond these two main approaches, two additional mixed approaches have recently been considered. Hybrid Transactional Memory (HyTM) [9], [10] supports transactional execution that generally occurs using HTM transaction but which backs off to STM transactions when hardware resources are exceeded. Hardware-assisted STM (HaSTM) combines STM with new architectural support to accelerate parts of the STMs implementation [11], [12]. These designs are both active research topics and provide very different performance characteristics: HyTM provides near-HTM performance for short transactions, but a “performance cliff” when falling back to STM.
