چکیده

We study the effect of irregular function behavior and dynamic task partitioning on the parallel performance of the adaptive multivariate integration algorithm currently incorporated in ParInt. In view of the implicit hot spots in the computations, load balancing is essential to maintain parallel efficiency. A convergence model is given for a class of singular functions. Results are included for the computation of the cross section of a particle interaction. The adaptive meshes produced by ParInt for these problems are represented using the ParVis visualization tool.

Design and Evaluation of a Method for Partitioning and Offloading Web-based Applications in Mobile Systems with Bandwidth Constraints

Computation offloading is known to be among the effective solutions of running heavy applications on smart mobile devices. However, irregular changes of a mobile data rate have direct impacts on code partitioning when offloading is in progress. It is believed that once a rate-adaptive partitioning performed, the replication of such substantial processes due to bandwidth fluctuation can be avoid...

Prediction of slope stability using adaptive neuro-fuzzy inference system based on clustering methods

Slope stability analysis is an enduring research topic in the engineering and academic sectors. Accurate prediction of the factor of safety (FOS) of slopes, their stability, and their performance is not an easy task. In this work, the adaptive neuro-fuzzy inference system (ANFIS) was utilized to build an estimation model for the prediction of FOS. Three ANFIS models were implemented including g...

Evaluating Locality Optimizations For Adaptive Irregular Scientific Codes

Irregular scientific codes experience poor cache performance due to their memory access patterns. Researchers have proposed several data and computation transformations to improve locality in irregular scientific codes. We experimentally compare their performance and present GPART, a new technique based on hierarchical clustering. Quality partitions are constructed quickly by clustering multipl...
