Evaluation of LH*LH for a Multicomputer Architecture
نویسندگان
چکیده
Scalable, distributed data structures can provide fast access to large volumes of data. In this paper, we present a simulation study in which the performance behaviour of one of these data structures, called LH*LH, is evaluated for a multicomputer architecture. Our experimental results demonstrate that the access-time to LH*LH can be very small and does not deteriorate for increasing data structure sizes. Furthermore, we also show that parallel access to the LH*LH data structure may speed up client applications. This speed-up is, however, shown to be constrained by a number of effects.

LH*LH: A scalable High Performance Data Structure for Switched Multicomputers
Abs t r ac t . LH*LH is a new data structure for scalable high-performance hash files on the increasingly popular switched multicomputers, i.e., MIMD multiprocessor machines with distributed RAM memory and without shared memory. An LH*LH file scales up gracefully over available processors and the distributed memory, easily reaching Gbytes. Address calculus does not require any centralized compo...

Background: Prescription of the atypical antipsychotic drugs like as Sulpiride for the treatment of schizophrenic patients was increased because of their less side effects. This study was aimed to evaluate the effect of sulpiride on hormonal milieu of adult male mice namely their serum level of prolactin and sexual hormones. Materials and Methods: 24 adult male mice were divided in three groups...

Classic one-dimensional data structures are very important. Nevertheless, the new data management systems (CAD, Web,..) need new access methods that support efficiently spatial operations on multi-attributes (multidimensional ) data files. Scalable Distributed Data Structures (SDDS) is a new class of data structures conceived specially for multicomputers: collection of PCs and workstations inte...
متن کاملI-24: Individualized Controlled Ovarian Stimulation (iCOS)
Background: With the recent development of recombinant gonadotropins (FSH and LH), it has become possible to further adjust the stimulation protocol according to the expected needs of the patient. In this respect, the possible beneficial role of exogenous LH activity supplementation for stimulated ART cycles has received increasing attention. According to the two-cell, two- gonadotropin theory,...
