This paper presents a hybrid shared memory architecture which combines the scalability of a multistage interconnection network with the contention reduction benefits of coherent caches. We achieve this by replacing the memory modules and final stages of a multistage interconnection network with clusters of coherent caches. The performance of Cache Coherent Hybrid Interconnected Memory Extension...

Preconditioning methods can help explicit multistage multigrid flow solvers to achieve fast and accurate convergence for a wide range of Mach numbers including incompress-ible flows. The implementation of preconditioning methods and the corresponding matrix dissipation terms in existing flow solvers is a challenging task if good convergence rates are to be obtained. This task can be made more c...

OBJECTIVES The relation between blood lead concentration (PbB) and blood pressure was examined in a Taiwan nationwide population survey of PbB from July 1993 to June 1994. METHODS After multistage sampling procedures, 2800 subjects (1471 males and 1329 females) with a mean (range) age of 44 (15-85) years were enrolled in this study. Anthropometric, blood pressure, and lifestyle factors were m...

Fouling is the most important performance degradation factor, so it is necessary to accurately predict the effect of fouling on engine performance. In the previous research, it is very difficult to accurately model the fouled axial flow compressor. This paper develops a new performance calculation method of fouled multistage axial flow compressor based on experiment result and operating data. F...

A double-blind study of the effects of isosorbide dinitrate, 10 mg given orally four times a day, propranolol, 40 mg four times a day, and the combination of these two drugs was performed on 21 patients with angina pectoris. Each patient received placebo, isosorbide, propranolol, and the combination of the two drugs for 1 month each in a random sequence over 4 months. The number of anginal pain...

The choice of an interconnection network for a parallel computer depends on a large number of performance factors which are very often application dependent. We propose a performance evaluation and a comparison methodology. This methodology is applied to a recently introduced class of interconnection networks (Multistage Chordal Ring Based multistage interconnection network). These networks are...
