By varying key work stealing parameters, we expose important tradeoffs between the granularity of load balance, the degree of parallelism, and communication costs. Since dynamic load balancing requires intensive communication, performance portability remains difficult for applications such as UTS and performance degrades on PC clusters. Benchmarks (2) (BT, CG, EP, FT, IS, LU, MG, SP), two appli-cations using work stealing from the UPC Task Library (9) (b, nqueens), three applications in the UPC test suite (guppie, laplace, mcop) and Unbalanced Tree Search (UTS) (11). However, UPC cannot alleviate the underlying communication costs of distributed-memory systems. Results show that both UPC and OpenMP can support efficient dynamic load balancing on shared-memory architectures. We found it simple to implement UTS in both UPC and OpenMP, due to UPC's shared-memory abstractions. We benchmarked the performance of UTS on various parallel architectures, including shared-memory systems and PC clusters. The size and shape of the tree are random and inferring these parameters from any node in the tree would require a shortcut to solving the SHA-1 secure hash algorithm.

The UTS benchmark presents significant load imbalance problems to any parallelization scheme. ![]() PotentialCUDAScientific computing UIUC Parboil Benchmark MRI-FHDMagnetic.

Our approach demonstrates low overheads and improved performance (relative to MPI and UPC versions) for up to 12288 cores on the NERSC Edison system. as exempli ed by the UTS and NQueens benchmarks. What does UTS stand for in Benchmark Get the top UTS abbreviation related to Benchmark. Lawrence Berkeley National Laboratory, Berkeley, California Vivek Sarkar. We created versions of UTS in two parallel languages, OpenMP and Unified Parallel C (UPC), using work stealing as the mechanism for reducing load imbalance. passing (MPI) is examined using two approaches (work stealing and work sharing). Benchmark UTS abbreviation meaning defined here. We describe algorithms for building a variety of unbalanced search trees to simulate different forms of load imbalance. This paper presents an unbalanced tree search (UTS) benchmark designed to evaluate the performance and ease of programming for parallel applications requiring dynamic load balancing.
