Abstract: A method is presented for processing one or more instructions to be executed on multiple threads in a Single-Instruction-Multiple-Data (SIMD) computing system. The method includes the steps of analyzing the instructions to collect divergent threads among a plurality of thread groups of the multiple threads; obtaining a redirection array for thread-operand association adjustment among the divergent threads according to the analysis, where the redirection array is used for exchanging a first operand associated with a first divergent thread in a first thread group with a second operand associated with a second divergent thread in a second thread group; and generating compiled code corresponding to the instructions according to the redirection array.

Abstract: A memory management method includes: checking shared virtual memory (SVM) support ability of at least one device participating in data access of a buffer; referring to a checking result to adaptively select an SVM mode; and allocating the buffer in a physical memory region of a memory device, and configuring the buffer to operate in the selected SVM mode.
