In another embodiment, please refer to fig. 2, in order to facilitate understanding of the technical solution of the present invention, an AI server including 8 AI accelerator CARDs and 8 indicator lamps is taken as an example for description, assuming that 8 AI accelerator CARDs ID are respectively denoted as CARD0 to CARD7, a Slot in which an AI accelerator CARD is located is respectively denoted as Slot0 to Slot7, and 8 indicator lamp index numbers located at one side of the AI accelerator CARD and corresponding to the AI accelerator CARDs are respectively denoted as LED0 to LED7, where the method for indicating the operating status of the AI server accelerator CARD provided in this embodiment specifically includes the following steps:
s01, the BIOS is responsible for collecting 8 accelerator CARD IDs, recording the 8 accelerator CARD IDs as CARD0 to CARD7 respectively and transmitting the 8 accelerator CARD IDs to the BMC; specifically, resource allocation and ID allocation are carried out on PCIE Slot positions of a mainboard according to hardware design at the initial stage of POST (power on self test), Slot IDs of the PCIE Slot positions are read and matched with Slot IDs in a Slot silk-screen table, and if matching is successful, corresponding silk-screen information and PCIE equipment information (namely CARD 0-CARD 7) are taken out from the Slot silk-screen table and sent to a BMC through CPU packaging.
S02, the CPLD establishes the index numbers of the LEDs, namely the LEDs 0 to the LEDs 7, according to the sequence from left to right, and establishes the corresponding relation between the index number of each LED and the slot position ID;
s03, the BMC continuously polls the temperature, Power consumption, asset information, video memory ECC error, Thermal Alert state, Power Brake state and the like of each accelerator card through SMBUS protocol. When ECC errors occur, state information such as Thermal Alert, Power Brake and the like is regarded as an abnormal state.
And S04, when the BMC inquires the state information, confirming each Slot ID and corresponding state information according to the corresponding relation between the accelerator card ID and the PCIE Slot, and transmitting the state information to the CPLD chip.
And S05, after receiving the BMC polling information, the CPLD determines the corresponding LED index number according to the slot ID, and sets the corresponding color or flicker of the LED lamp corresponding to the index state information.
For example, an uplink communication link of the CPLD chip is connected to the BMC, receives a control instruction sent by the BMC through the SMBUS communication protocol, and a downlink communication link is connected to a signal control port of the LED through the GPIO line. The LED adopts a mature multicolor LED display scheme, can display various colors, and the different colors respectively represent different operating states of the accelerator card. For example, green generally represents normal; red for over-temperature; orange represents insufficient power supply; purple indicates the presence of ECC errors; yellow flashes represent a need to be reset. Each LED has a plurality of control pins and a ground terminal, and the LED can display different colors after the levels of different control pins are pulled up. When the level signal has a PWM waveform, flicker occurs.
Assuming that when all AI acceleration cards in the read state information are in a normal state in the current polling period BMC, the BMC transmits the information to the CPLD through the SMBUS protocol, and the CPLD controls the LEDs 0 to the LED7 to be green; when the next polling cycle BMC reads that the accelerator CARDs CARD 0-CARD 6 are normal, the accelerator CARD CARD7 has overhigh temperature, the CPLD controls the LEDs 0-LED 6 to be green at the moment, and the output signal of the LED7 is changed to display red.
According to the method, the LEDs are added beside the PCIe slot positions where the AI acceleration board cards are located, the state information of the AI acceleration board cards is collected through the BMC, the slot position information and the operation information corresponding to the acceleration board cards are sent to the CPLD through the BMC, and therefore the LED display state control of the corresponding states of the acceleration board cards is carried out through the CPLD chip.
