Abstract: A remote data access method is applied to a first device that is coupled to and communicates with a second device. The first device and the second device each are configured with a network interface card (NIC) having a remote direct memory access (RDMA) function. The method is performed by a NIC of the first device, and the method includes: generating a first packet including a type identifier and a function identifier; and sending the first packet to the second device. The type identifier in the first packet indicates that the first packet is a remote memory function call (RMFC)-type packet, and the RMFC-type packet indicates the second device to perform a preset operation on local data of the second device. The function identifier in the first packet indicates an operation type of the preset operation.

Abstract: This application discloses a floating-point number multiplication computation method, an apparatus, and an arithmetic logic unit. The method includes: obtaining a plurality of to-be-computed first-precision floating-point numbers; decomposing each to-be-computed first-precision floating-point number to obtain at least two second-precision floating-point numbers, a second precision of the second-precision floating-point number is lower than a first precision of the first-precision floating-point number; determining various combinations including two second-precision floating-point numbers obtained by decomposing different first-precision floating-point numbers; inputting the second-precision floating-point numbers in each combination into a second-precision multiplier to obtain an intermediate computation result corresponding to each combination; and determining a computation result for the plurality of to-be-computed first-precision floating-point numbers based on the intermediate computation result corresponding to each combination.

Abstract: An operation unit, and a floating-point number calculation method and apparatus are provided. The operation unit includes a disassembly circuit and an arithmetic unit. The disassembly circuit may obtain a mode and a to-be-calculated floating-point number that are included in a calculation instruction, and disassemble the to-be-calculated floating-point number according to a preset rule. Then, the arithmetic unit completes processing of the calculation instruction based on the mode and the disassembled to-be-calculated floating-point number.
