Any collection of views can be displayed while a sequencer plays back the state trace on every view simultaneously, in real time proportional to observed event timing. Parts of the state of the network more » are displayed as colorations of otherwise static displays, where parameters are represented as immobile display objects and the object's color codes the value of its parameter. The user defines a mapping from parameter values to colors for six different parameter types. States are viewed as collections of scalar-execution parameters. And finally, drag that cube along the w axis to create a 4D hypercube An interesting pattern can be observed here: a line had 2 points, a square had 4 lines, and a cube had 6 squares, so it follows that our tesseract will have 8 cubes. Drag that square along the z axis to create a 3D cube. Seecube is an interactive graphical analysis tool for viewing these state traces. Drag that line along the y axis to create a 2D square. He combines event traces from all processors into a single global-event trace, and uses this to compute a state trace for the entire network of processors. Using the Intel iPSC and NCUBE hypercubes as examples, the author shows how global performance of a message-passing multiprocessor can be reconstructed from event traces of message-passing activity for each constituent processor. The demonstration code used for this work is a Monte Carlo simulation of the response to photons of a ''nearly realistic'' lead, iron and plastic electromagnetic and hadronic calorimeter, using the EGS4 code system. These parallel machines are typical MIMD types with from 8 to 30 processors, each rated at from 1 to 10 MIPS processing power. Benchmark results are presented for parallel computers such as the Alliant more » FX/8, the Encore MultiMax, the Sequent Balance, the Intel iPSC/2 Hypercube and a network of Sun 3 workstations. The parallelism is implemented using standard UNIX (tm) tools and a small number of easily understood synchronization concepts (monitors and message-passing techniques) to construct and coordinate multiple cooperating processes on one or many processors. Fortran programs with intrinsic parallelism of coarse and medium granularity are easily converted to parallel programs which are portable among a number of commercially available parallel processors in the class of shared-memory bus-based and local-memory network based MIMD processors. Compared with the traditional typhoon simulation method, the improved typhoon simulation method has higher accuracy in predicting the typhoon extreme wind speed in Hong Kong, increasing by about 8% and 11% respectively at 200 m height and gradient height.Experience using the Argonne-developed PARMACs macro package to implement a portable parallel programming environment is described. The results show that the improved typhoon simulation method can generate the correlations among all typhoon key parameters satisfactorily. The results show that the correlation coefficients among typhoon key parameters can be maintained satisfactorily with this improved typhoon simulation method. To validate this method, two aspects of analysis is carried out, including correlation analysis among typhoon key parameters and prediction of extreme wind speeds under various return periods. Then, this method is applied to the prediction of extreme wind speeds under various return periods in Hong Kong. Whether to use an optimization scheme to improve the quality after sampling. In this paper, the improved typhoon simulation method is first given a detailed introduction. Again these numbers are transformed using the function to give our required sample. However here the interval 0,1 is divided into portions and a number is sampled randomly from each interval. In order to further improve the prediction accuracy of typhoon simulation method for extreme wind speed in typhoon prone areas, an improved typhoon simulation method is proposed by introducing the Latin hypercube sampling method into the traditional typhoon simulation method. The following is a code for a Latin Hypercube Simulation.
