Optimization of thread partitioning parameters in speculative multithreading based on artificial immune

Yu-xiang LI,Yin-liang ZHAO,Bin LIU,Shuo JI

Frontiers of Information Technology & Electronic Engineering 2015, Volume 16, Issue 3,   Pages 205-216 doi: 10.1631/FITEE.1400172

Abstract: Thread partition plays an important role in speculative multithreading (SpMT) for automatic parallelization of irregular programs. Using unified values of partition parameters to partition different applications leads to the fact that every application cannot own its optimal partition scheme. In this paper, five parameters affecting thread partition are extracted from heuristic rules. They are the dependence threshold (DT), lower limit of thread size (TSL), upper limit of thread size (TSU), lower limit of spawning distance (SDL), and upper limit of spawning distance (SDU). Their ranges are determined in accordance with heuristic rules, and their step-sizes are set empirically. Under the condition of setting speedup as an objective function, all combinations of five threshold values form the solution space, and our aim is to search for the best combination to obtain the best thread granularity, thread dependence, and spawning distance, so that every application has its best partition scheme. The issue can be attributed to a single objective optimization problem. We use the artificial immune algorithm (AIA) to search for the optimal solution. On Prophet, which is a generic SpMT processor to evaluate the performance of multithreaded programs, Olden benchmarks are used to implement the process. Experiments show that we can obtain the optimal parameter values for every benchmark, and Olden benchmarks partitioned with the optimized parameter values deliver a performance improvement of 3.00% on a 4-core platform compared with a machine learning based approach, and 8.92% compared with a heuristics-based approach.

A density functional theory study of methane activation on MgO supported NiM cluster: role of M on C–H

Frontiers of Chemical Science and Engineering 2022, Volume 16, Issue 10,   Pages 1485-1492 doi: 10.1007/s11705-022-2169-8

Abstract: In present work, methane activation on MgO supported Ni–M (M = Fe, Co, Cu, Pd, Pt) cluster was exploredthrough detailed density functional theory calculations, compared to pure Ni cluster.CH4 adsorption on Cu promoted Ni cluster requires overcoming an energy of 0.07 eV, indicatingDoping elements of the same period in Ni cluster, such as Fe, Co and Cu, for C–H bond activation followsConsequently, C–H bond activation demands a lower energy barrier on Ni–Pt cluster.
