Embodiment 1

[0229] The software and hardware environment parameters of Shenwei 26010 heterogeneous many-core processor are:

[0230] Table 1 Software and hardware environment

[0231] CPU Memory translater SW26010 1.45GHz 32G for 4CG Sw5cc

[0232] The data used in Example 1 is grid point data with a grid size, and a point source is used to solve the quark propagator. The ratio of the operation time of each part of the program and the acceleration effect of parallel computing are analyzed.

[0233] The data cutting method of the present invention can improve the bandwidth utilization rate (indicated by DMA in the present invention) between the slave core and the main memory, and reduce the transmission of redundant data. Compared with the serial computing method, because the data redundancy is reduced by 8 times, and the number of direct memory access transmissions is reduced, the experimental results are shown in Table 2, and the performance is improved by 14...

Abstract

The invention discloses a lattice point quantum color dynamics parallel acceleration method based on a heterogeneous many-core processor. The lattice point quantum color dynamics parallel accelerationmethod comprises the following steps: step 1, carrying out position division on a slave core according to a slave core identification number; step 2, storing read data information according to the position of a four-dimensional space; step 3, reading a grid point numerical value which is responsible for calculation from a memory by the slave core according to the position identification of the slave core; and step 4, carrying out lattice point numerical value iterative updating on any slave core to obtain updated lattice point numerical values belonging to the slave cores. The lattice point quantum color dynamics parallel acceleration method is a parallelization method for Shenwei 26010 heterogeneous many-core processors, fully utilizes unique register communication characteristics amongthe Shenwei many-core processors, improves data reusability, and reduces a large amount of redundant data. After parallel acceleration, compared with operation only on a main core, the lattice point quantum color dynamics parallel acceleration method improves the performance by 63 times.
