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.
