This paper examines the eeectiveness of load balancing strategies for ray tracing on large parallel computersystems and cluster computers. Popular static load balancing strategiesare shown to be inadequate for rendering complex images with contemporary ray tracing algorithms, and for rendering NTSC resolution images on 128 or more computers. Strategies based on image tiling are shown to be inee...

In Japan, many concrete bridges along the coastline have suffered corrosion due to the chloride attack from seawater and airborne salt. Therefore, now, several researches on corroded RC structures have been ongoing around the world. Especially, as a basic research, many researchers have studied on the numerical and experimental method to evaluate static load resistant capacity of RC beams with ...

Load balancing is the process of improving the performance of a peer to peer networks through a redistribution of load among the processors. In this paper we present the performance analysis of various load balancing algorithms based on different parameters, considering two typical load balancing approaches static and dynamic. The analysis indicates that static and dynamic both types of algorit...

The present study examines how various types of attention cueing and cognitive preference affect learners’ comprehension of a cardiovascular system and cognitive load. EFL learners were randomly assigned to one of four conditions: non-signal, static-blood-signal, static-blood-static-arrow-signal, and animation-signal. The results indicated that attention cueing yielded similar performance but h...

In this paper, several scenarios for helper threading were implemented and analyzed on the SPEC2000 mcf benchmark [1]. After determining the delinquent load of the mcf benchmark, three helper threading scenarios were implemented to prefetch the delinquent load into L2 cache. First a static loop-based helper process was implemented, followed by a static loop-based helper thread. Finally, a stati...

This paper describes the experimental studies of vertical dynamic stiffness of single piles subjected to small amplitude of vibrations with constant dynamic load. The test results were correlated with the static load test results that had been carried out on the same piles. The ratio of dynamic to static stiffness mainly falls between 1.2-1.4. The dynamic stiffness measurements were compared wi...

The present study examines how different types of attention cueing and cognitive style affect learners’ comprehension of a cardiovascular system and cognitive load. In this study, the learners were randomly assigned into one of following groups: no-cueing, static-blood cueing, static-blood–static-arrow cueing, and dynamic-blood–dynamic-arrow cueing. The results showed that attention cueing yiel...

Parallelizing a problem by statically assigning a xed number of subprob-lems to each processor is very popular due to its simplicity and low communication overhead. In many cases it can be proved to be suucient to randomly assign O(log N) subproblems to each of N processors in order to smooth out load imbalance due to varying subproblem sizes. However, this is not true for the tree structured c...
