When the 4-path server is provided with only two processors, only one path of bus is connected between the processors; after the connecting device is added, the connecting bandwidth between the processors can be increased, the processors are interconnected by three buses, which is three times of the bandwidth of the traditional scheme, so that the interconnection bandwidth between the processors is greatly increased, and the data access delay is reduced.
In this embodiment, the embodiment of the present application provides a four-way server, which has the following beneficial effects: according to the application, the two connecting devices capable of receiving and transmitting clock signals are additionally arranged, and the time data ends and the clock ends of the two processors are connected in series through the two connecting devices, so that the bandwidth of the four-way server is increased, the communication rate is improved, and the data access delay is reduced.
Referring to fig. 5, a flow chart of an initialization method of a four-way server according to an embodiment of the present application is shown.
In an embodiment, the method for initializing the four-way server is applicable to the four-way server described in the above embodiment.
In an embodiment, different four-way servers need to configure different files for initialization processing, so as to accurately perform initialization processing according to placement positions of each processor in the four-way servers, where, as an example, the method for initializing the four-way servers may include:
s11, after the level detection signals of the CPU slots of the four-way server are obtained, the installation state of the CPU slots is determined according to the level detection signals, and the installation type comprises an in-place state and a type state.
An interface capable of collecting signals is designed on the CPU slot (CPU SOCKET), the level detection signal of the CPU slot (CPU SOCKET) can be detected, and whether the CPU slot (CPU SOCKET) is provided with an installation processor or a connection device is determined through the level detection signal; still alternatively, it may be determined by the level detection signal that the CPU SOCKET (CPU SOCKET) is currently mounted with a processor or a connection device.
Wherein the in-place state refers to whether a processor or a connecting device is installed; the type state means that the CPU SOCKET (CPU SOCKET) is currently installed with a processor or a connection device.
In one implementation, a level detection signal may be sent to a CPU SOCKET (CPU SOCKET), and then a level detection signal may be collected at an output terminal, and the bit state and the type state may be determined by determining whether the level detection signal is at a high level or a low level.
It should be noted that, the detection signals of the bit state and the type state may be connected to the GPIO of the CPU0 to enable the BIOS to obtain the installation information of other SOCKET.
In an alternative embodiment, the determination of the bit state may include the following sub-steps:
and S21, if the level detection signal is at a low level, determining that the in-place state is a mounting processor or a mounting connection device.
And S22, if the level detection signal is at a high level, determining that the bit state is a state that the processor is not installed or the connecting device is not installed.
Specifically, a detection signal for detecting an in-place state can be sent to a main board of the four-way server, the main board can pull up the in-place detection signal to be high level through a pull-up resistor, and if a processor or a connecting device is not installed in a CPU slot (CPU SOCKET), the signal is still high level at the moment; when the CPU SOCKET (CPU SOCKET) is provided with a processor or a connecting device, the processor or the connecting device strongly pulls down the bit signal, and the signal is at a low level. So that it can be determined whether the CPU SOCKET (CPU SOCKET) has the mounted processor or the connection means by the high and low level.
In an alternative embodiment, the determining the type state includes:
and S31, if the level detection signal is at a low level, determining that the type state is a CPU slot installation processor.
S32, if the level detection signal is at a high level, determining that the type state is the CPU slot installation connection device.
Specifically, the detection signal for performing the type state detection may also be sent to the motherboard of the four-way server, and the motherboard may pull the type detection signal high to a high level through a pull-up resistor. When the CPU slot (CPU SOCKET) installs the CPU, the CPU strongly pulls the signal low, and the type detection signal is at low level; when the connection means are installed, the connection means do not process the signal, which is still high. The technical effect of quickly determining the type of the device mounted in the CPU SOCKET (CPU SOCKET) is achieved through the high and low levels.
Referring to the following table, showing the state detection result, if a high level is represented by 1 and a low level is represented by 0, the bit state and the type state are as shown in the following table 1:
| status detection result | In-situ detection signal | Type detection signal | Code |
| SOCKET installs CPU | 0 | 0 | 00 |
| SOCKET mounting and connecting device | 0 | 1 | 01 |
