[0003] The purchase cost of three-way power supply control equipment is relatively high. For the increasing market competitiveness and the equipment cost of enterprises, if the product performance and quality are guaranteed, cost saving is particularly important for the survival of enterprises. Single-way There are also devices in the market, but they cannot switch modes, and they do not give full play to the performance of computing power devices, such as the common high computing power mode, high efficiency mode and balanced mode

Abstract
The invention discloses a method for controlling a multi-computing-power board based on a single-path power supply. The method is suitable for a main control board to control the single-path power supply to output voltage to multiple computing power boards, and is characterized by comprising the following steps: establishing a voltage, computing power board optimal frequency point and first computing power relationship correspondence table; establishing a voltage, calculation power board frequency point, second calculation power and total power relationship correspondence table; and accordingto the selected working mode, inquiring the voltage, the optimal frequency point of the computing power board and the first computing power relationship corresponding table or inquiring the voltage, the frequency point of the computing power board, the second computing power and the total power relationship corresponding table, and calculating and outputting corresponding voltage and characteristic frequency points to each computing power board. The invention further discloses a device for controlling the multi-computing-power board based on the single-circuit power supply. The invention relates to the technical field of power supplies. The method and the device for controlling a multi-computing-power board based on a single-path power supply overcome the technical problem of high cost ofthe existing three-path power supply control equipment, save the cost and can randomly switch the working modes of the computing power boards.
Description
technical field [0001] The present invention relates to the field of power supply technology, in particular to a method and device for controlling multiple computing power boards based on a single power supply. Background technique [0002] At present, most of the power supplies used by high-performance computing servers are three-way voltage output and single-way adjustable power supply equipment, which are basically based on certain protocols (such as I2C, SPI, etc.) The optimal state of computing power needs to be given different voltages and different operating frequencies. On the high-performance service board, it is necessary to continuously send instructions to the power supply to control the voltage on the board, so that the high-performance service board can work to the best of the corresponding mode. point. [0003] The purchase cost of three-way power supply control equipment is relatively high. For the increasing market competitiveness and the equipment cost of ...
