Improving Locality for Adaptive Irregular Scientific Codes
Irregular scientific codes experience poor cache performance due to their memory access patterns. In this paper, we examine three issues for locality optimizations for irregular computations. First, we experimentally determine efficient parameters for optimizations based on partitioning algorithms. Second, we find locality optimizations can improve performance for parallel codes, but is depende...
متن کاملLocality Optimizations For Adaptive Irregular Scientific Codes
Irregular scientific codes experience poor cache performance due to their memory access patterns. We examine several data and computation locality transformations including GPART, a new technique based on hierarchical clustering. GPART constructs quality partitions quickly by clustering multiple neighboring nodes in a few passes, with priority on nodes with high degree. Overhead is kept low by ...
متن کاملSulphate, Phosphate and Histidine Conjugations
Phenols were detoxified in the Onycophoran Peripatoides novaezealandiae by conjugation with sulphuric acid and phosphoric acid, but no evidence for a glycoside detoxication could be found. [14C]Benzoic acid was metabolized in 24h to N2-benzoyl-L-histidine, which was identified by electrophoresis, chromatography and dilution analysis. Similar conjugates were formed with p-aminobenzoic acid and p...
متن کاملFixed Points of Generalized Conjugations
Conjugation, or Legendre transformation, is a basic tool in convex analysis, rational mechanics, economics and optimization. It maps a function on a linear topological space into another one, defined in the dual of the linear space by coupling these space by meas of the duality product. Generalized conjugation extends classical conjugation to any pair of domains, using an arbitrary coupling fun...
متن کاملReducing Communication Cost for Parallelizing Irregular Scientific Codes
In most cases of distributed memory computations, node programs are executed on processors according to the owner computes rule. However, owner computes rule is not best suited for irregular application codes. In irregular application codes, use of indirection in accessing left hand side array makes it difficult to partition the loop iterations, and because of use of indirection in accessing ri...
