Description

technical field [0001] The invention relates to the technical field of high-performance computer numerical simulation, in particular to a general algorithm based on a variational multi-scale method and a parallel computing system. Background technique [0002] Computer simulation has become the third basic method of scientific research and technology development alongside theory and experiment, and it is also the main application direction of high-performance computing. But at present, the development of high-performance computing systems is mainly driven by the development of hardware technology, and the corresponding computer systems have not been designed based on the common characteristics of computer simulation. Therefore, as the component technology marked by the line width of integrated circuits is gradually approaching the limit under current conditions, the bottleneck of further improving computing power is becoming more and more prominent, which is mainly manifeste...

AI Technical Summary

Problems solved by technology

At present, even for single-processor microcomputers, the widening speed gap between the data processing speed of the processor and the data access speed of the memory makes it only about 10% of the peak value of the actual efficiency of running many calculation programs. For MPP systems, it is often reduced to only 1-2%

[0004] 2) The accuracy of the calculation method is increasingly incompatible with the complexity of the simulated object

[0005] 3) The gap between the popularity of high-performance computing and the demand for high-performance computing is growing

[0043] Although the above-mentioned patent application considered the multi-scale effect (multi-layer direct connection and the coupling of processing chips with different properties) and the generalization of the short-range effect model (local memory sharing and short-range direct connection mode), it has not systematically considered the more general meaning A dedicated computing system for the multi-scale discrete simulation system under the multi-scale discrete simulation system; although the connection between the upper and lower units is used to deal with the long-range correlation between the model units, it has not been proposed to use the variational multi-scale method to constrain the role of the model units, simplify the calculation, and improve Efficient system approach, as well as the reliability and flexibility of large-scale parallelism, as well as the optimization of calculation, storage and communication speed matching, etc.
