The majority of auto-tuning research in HPC to date has focused on improving the performance of a single objective function. More recently, interest has grown in optimizing multiple objective functions simultaneously, for example balancing the trade-off between execution time and energy consumption. Evolutionary algorithms for multi-objective optimization(More)
Application auto-tuning has produced excellent results in a wide range of computing domains. Yet adapting an application to use this technology remains a predominately manual and labor intensive process. This paper explores first steps towards reducing adoption cost by focusing on two tasks: parameter identification and range selection. We show how these(More)
This study was designed to compare the surface change in 6 brands of composite resins immersed in 4 topical fluoride gels of various pH. The result was evaluated by visual change in light reflectance and SEM. The findings were as follows: 1) five 4-minute immersions in acidic fluoride gels increased surface roughness and decreased the light reflectance of(More)
The benefit of automated application tuning has been the focus of numerous research projects, yet applying this technology remains a completely manual and labor-intensive process. This paper explores first steps towards reducing the adoption cost of auto-tuning in the context of Chapel; a parallel programming language whose development is being led by Cray(More)
The quantum-chemical calculation of an entire molecule of hagfish insulin was done by the ENFC method in which the matrix elements were calculated at the ab initio level using a minimal basis set with simulation of the aqueous solution environment. The ac conductivity for hagfish insulin was also calculated at the ab initio level by random walk theory. All(More)
This paper is a quality control system involved in using data mining to discover the main inconsistency reasons in the manufacturing process of semiconductor plants and compare the correctness of classification analysis of the two methods, so as to set up a quality control system providing an efficiency tool for analyzing problems, with a view to(More)
