Embodiment approach

[0041] According to an implementation manner of this embodiment, the general-purpose multi-core processor 101 is a Xeon series processor of Intel (Intel). According to another implementation manner of this embodiment, the general-purpose multi-core processor 101 is a Phenom series processor of AMD.

[0042]The storage bus 102 connects the plurality of general multi-core processors and the shared memory 103 , and is used for realizing reading and writing of the shared memory 103 by the plurality of general multi-core processors 101 . The memory bus 102 includes address lines and data lines. The address lines are used to transmit address signals to determine the address of the storage unit read or written by the general multi-core processor 101 at a certain moment. The data lines are used for transmitting data signals. The general multi-core processor 101 transmits data information for reading or writing to the shared memory 103 through the data line.

[0043] The shared memo...

Abstract

The invention discloses a multiscale-calculation-oriented computer system. The computer system comprises a plurality of general multi-core processors, a multi-instruction multi-data many-core processor, a single-instruction multi-data many-core processor and a network interface card, wherein the plurality of general multi-core processors are used for control and scheduling of the calculating process; the multi-instruction multi-data many-core processor is used for processing calculation tasks with more judgments and branches; the single-instruction multi-data many-core processor is used for processing calculation tasks with less judgments and branches; and the network interface card is used for connecting the computer system with a computer network. By adoption of the computer system provided by the invention, the calculation tasks with different characteristics in the multiscale calculation can acquire matchable efficient execution components, and the total efficiency of calculation is improved, so that the evaluation time is shortened and the operating cost is reduced.

Description

technical field [0001] The invention relates to the field of high-performance computers, in particular to a multi-scale computing-oriented computer system. Background technique [0002] With the rapid development of modern science and technology, traditional scientific experiments and theoretical research methods can no longer fully meet the needs of contemporary scientific research and technological progress. Accelerator" has received more and more attention. Large-scale computer simulation is based on computing power, and uses numerical calculation methods based on the theoretical model of the research target to conduct virtual experiments on the computer. Large-scale computer simulation is characterized by low cost, short period, convenience and flexibility, and wide application. It can even simulate scientific experiments that cannot be realized by modern human technology, such as the evolution of galaxies and the formation of the universe. Therefore, supercomputing sy...
