FIG. 1 is a schematic diagram of a hardware resource sharing system 100 according to an embodiment of the present invention. The hardware resource sharing system 100 includes a connection bridge platform 110 and a shared resource controller 120. The shared resource controller 120 is coupled to the connection bridge platform 110.

In FIG. 1, the connection bridge platform 110 includes bus bars BUS ₁ to BUS ₁₈ and bridge devices SW ₁ to SW ₉ supporting a Peripheral Component Interconnect Express (PCIE) transmission format. Each of the bridge devices SW ₁ to SW ₉ has six input and output ports, and the shared resource controller 120 is capable of controlling the internal connection relationship of each of the input devices SW ₁ to SW ₉ .

In Fig. 1, the bridge device SW ₁ can be connected to the bus bars BUS ₁ to BUS ₃ , the bridge device SW ₂ can be connected to the bus bars BUS ₄ to BUS ₆ , and the bridge device SW ₃ can be connected to the bus bars BUS ₇ to BUS ₉ The bridge devices SW ₁ to SW ₃ may each be connected to the bridge devices SW ₄ to SW ₆ , respectively, and the bridge devices SW ₄ to SW ₆ may be respectively connected to the bridge devices SW ₇ to SW ₉ , respectively, and the bridge device SW ₇ may be connected to the bus bar BUS ₁₀ to BUS ₁₂ , bridge device SW ₈ can be connected to bus bars BUS ₁₃ to BUS ₁₅ , and bridge device SW ₉ can be connected to bus bars BUS ₁₆ to BUS ₁₈ . In this way, through the control of the shared resource controller 120, the electrical connection between the bus bars BUS ₁ to BUS ₁₈ can be flexibly established.

In order to enable the computer host coupled to the hardware resource sharing system 100 to flexibly share the peripheral devices coupled to the hardware resource sharing system 100, the user can set the preset connection group of the hardware resource sharing system 100 according to requirements. The CONF, and the shared resource controller 120 controls the connection bridge platform 110 according to the preset connection configuration CONF. The preset connection configuration CONF may include the number, type, and/or usage information of peripheral devices supported by the hardware resource sharing system 100, the number of supported computer hosts, and the bus bars BUS ₁ to BUS ₁₈ and Information such as the preset connection configuration between the bridge devices SW ₁ to SW ₉ .

The shared resource controller 120 can control the connection bridge platform 110 to set the bus bars BUS ₁ to BUS ₁₈ according to the preset connection configuration, the number of peripheral devices that can be supported in the CONF, and the number of supported computer hosts. It is a busbar for a plurality of peripheral devices and a plurality of computer host busbars. For example, in FIG. 1, the shared resource controller 120 can set the bus bars BUS ₁ to BUS ₉ as computer host bus bars, and can set the bus bars BUS ₁₀ to BUS ₁₈ as peripheral device bus bars. The mainframe bus bars BUS ₁ to BUS ₉ can be used to be coupled to external computer hosts C ₁ to C ₉ , and the peripheral device bus bars BUS ₁₀ to BUS ₁₈ can be used to couple with external peripheral devices B ₁ to B ₉ . Pick up. The shared resource controller 120 can configure the CONF control connection bridge platform 110 according to the preset connection to establish an electrical connection between the computer host bus bars BUS ₁ to BUS ₉ and the peripheral device bus bars BUS ₁₀ to BUS ₁₈ . connected to a corresponding host computer to further a C ₁ to C ₉ peripheral device B ₁ to B _9. The peripheral devices B ₁ to B ₉ can be, for example, a network interface controller (NIC), a general purpose graphic processing unit (GPU), and a non-volatile memory (Non-volatile Memory). Hardware resources such as Express Solid State Drive (NVMe SSD) and Fiber Channel Host Bus Adapter (HBA).

In the above embodiment, each of the bridge devices SW ₁ to SW ₉ has six input and output ports, and can be docked in a three-to-three manner, but the invention is not limited thereto. In other embodiments of the present invention, the connection bridge platform 110 can also be implemented by using other types of bridge devices, for example, each input/output port can be arbitrarily connected to other input and output ports, with a greater number of inputs. The bridging device of the output crucible, or the bridging device with other docking methods, can even use different types of bridging devices at the same time. In other words, the user can select the appropriate bridging device to implement the connection bridging platform 110 according to the actual usage requirements, such as the number of computer hosts that want to share the hardware resources, and the number of peripheral devices available for sharing.

In addition, the connection bridge platform 110 and the bridge devices SW ₁ to SW ₉ shown in FIG. ₁ are merely illustrative, and in other embodiments of the invention, the bridge bridge platform 110 may also include other numbers of bridges. The device and the connection relationship between the bridge devices can also be adjusted according to actual needs, and all should fall within the scope of the present invention.

In order to enable the computer host coupled to the hardware resource sharing system 100 to flexibly utilize the peripheral devices reserved by the hardware resource sharing system 100, the computer host is coupled to the hardware resource sharing system 100 and performs peripheral components quickly. When the bus bar scanning function is interconnected, the shared resource controller 120 can replace the peripheral device with its associated usage message, so that the computer host can reserve the memory segment using its peripheral devices.

For example, in FIG. 1 , when the computer host C _{1 is} coupled to the host bus BUS ₁ and performs the peripheral component quick interconnect bus scanning function, the shared resource controller 120 can be connected according to a preset. CONF configuration corresponding to the type of host computer peripheral device bus corresponding to the plurality of peripheral device bus BUS of ₁ and / or information back to the host computer C _1, for example, if the host computer ₁ corresponding to the bus BUS to all The peripheral device bus BUS ₁₀ to BUS ₁₈ , at this time, the shared resource controller 120 can return the types and/or usage information of the peripheral devices B ₁ to B ₉ corresponding to the peripheral device bus bars BUS ₁₀ to BUS ₁₈ to The first computer host C ₁ . In this way, the first computer host C ₁ can know the peripheral devices that can be used, and can reserve the memory required to use the peripheral devices B ₁ to B ₉ according to the return information of the shared resource controller 120. Section.

However, at this time, the peripheral devices B ₁ to B ₉ may not be coupled to the peripheral device bus bars BUS ₁₀ to BUS ₁₈ . When the first computer host C ₁ wants to use a specific peripheral device, such as the peripheral device B ₁ , and the peripheral device B _{1 is} not coupled to the corresponding peripheral device bus BUS ₁₀ , the shared resource controller 120 can send a busy message to the computer. The host C ₁ makes the computer host C ₁ temporarily unable to use the specific peripheral device B ₁ .

Then, when the peripheral device B ₁ is coupled to the corresponding peripheral device bus BUS ₁₀ by a hot plug, the shared resource controller 120 can control the connection bridge platform 110 to establish the computer host bus BUS ₁ The electrical connection between the corresponding peripheral device bus BUS ₁₀ and the peripheral device BUS ₁₀ enables the computer host C ₁ to exchange data with the peripheral device B ₁ through the connection bridge platform 110 and can normally use the peripheral device B ₁ .

Since the memory segment using the peripheral device B ₁ has been reserved in advance in the computer host C ₁ , the peripheral device B ₁ can be coupled to the corresponding peripheral device bus bar BUS in a hot plug manner. ₁₀ , without being connected to the peripheral device bus BUS ₁₀ before the computer host C _{1 is} turned on. In this way, the user can decide whether it is necessary to purchase a new peripheral device B ₁ according to the usage of the system.

For example, although the hardware resource sharing system 100 can initially set the peripheral device supported by the computer host C ₁ to have 16 general-purpose graphics processors, the user does not need to set 16 general-purpose graphics at the beginning. The processor can be set up, for example, with four general-purpose graphics processors, and then consider whether it is necessary to add a general-purpose graphics processor depending on the operation of the system. Since the unit price of the general-purpose graphics processor is not low, such an elastic application for the entire system can not only greatly improve the efficiency of hardware use, but also reduce unnecessary waste of resources.

FIG. 2 is a usage context diagram of the hardware resource sharing system 100. In the second figure, when the computer host C _{2 is} coupled to the corresponding computer host bus BUS ₂ in the computer bus BUS ₁ to BUS ₉ , the computer host C ₂ also performs the peripheral component quick interconnection bus scanning function. In order to confirm the peripheral device that can be used, the shared resource controller 120 will return the usage information of the peripheral device corresponding to the peripheral device busbar of the computer bus BUS ₂ according to the preset connection configuration CONF. Pass to the computer host C ₂ . In the embodiment of FIG. ₂ , the peripheral device busbar corresponding to the computer host busbar BUS ₂ may be the peripheral device busbars BUS ₁₀ to BUS ₁₁ , so the shared resource controller 120 will correspond to the peripheral device B ₁ and The usage information of B ₂ is transmitted back to the computer host C ₂ , so that the computer host C ₂ can reserve the memory segment required for the corresponding peripheral devices B ₁ and B _{2 first} .

Although the computer host C ₂ and the first computer host C ₁ all correspond to the peripheral device B ₁ , in the same period, only one computer host can use the peripheral device B ₁ , and the shared resource controller 120 plays the center coordination. The role of the feet. For example, when the computer host C ₁ occupies the peripheral device B ₁ , if the computer host C ₂ also wants to use the peripheral device B ₁ , the shared resource controller 120 can send a busy message to the computer host C _{2 to} make the computer host Peripheral device B _{1 is} temporarily unavailable for C ₂ . Then, if the computer host C ₁ stops using the peripheral device B _{1 by itself} , or the computer host C ₁ notifies the peripheral device B ₁ via the shared resource controller 120, when the computer host C ₂ again sends out the handshake of the peripheral device B ₁ . When the message is received, the shared resource controller 120 will not send the busy message to the computer host C _{2 again} , so the computer host C ₂ can normally use the peripheral device B ₁ .

In some embodiments of the present invention, since the original shared resource controller 120 does not know what peripheral devices each computer host actually needs to use, when a computer host wants to use a specific peripheral device, the computer host and the like The connection between the peripheral devices used may not be established yet, so when the host computer sends a handshake message to a specific peripheral device, the shared resource controller 120 can dynamically control the connection bridge platform 110 to establish a host computer. The connection between the peripheral device and the peripheral device it is intended to use.

For example, in the above embodiment, when the host computer using a peripheral device to be C ₂ B _1, C ₂ corresponding to the host computer to the host computer bus and _a bus BUS ₂ corresponding to the peripheral device a peripheral device B BUS ₁₀ The connection may not be established between the two, so the shared resource controller 120 establishes a connection between the computer host bus BUS ₂ and the peripheral device bus BUS ₁₀ according to requirements, for example, through the bridge devices SW ₁ , SW ₆ and SW ₇ To establish a connection between the computer host bus BUS ₂ and the peripheral device bus BUS ₁₀ .

In some embodiments of the present invention, the shared resource controller 120 can obtain the information output by each computer host through the corresponding computer host bus through the computer bus BUS ₁ to BUS ₉ , so that each computer can be used according to each computer. The host uses the peripheral device to dynamically set the connection between the computer bus BUS ₁ to BUS ₉ and the peripheral device bus BUS ₁₀ to BUS ₁₈ , so that the computer host can be connected to the connection bridge by hot plugging. Peripheral device of platform 110.

In addition to being able to dynamically set the connection between the computer bus bars BUS ₁ to BUS ₉ and the peripheral device bus bars BUS ₁₀ to BUS ₁₈ , the hardware resource sharing system 100 can also reallocate the bus bar BUS according to the needs of the user. ₁ to the number of bus bars and peripheral devices in BUS ₁₈ . The user only needs to update the preset connection configuration CONF according to the required number of computer hosts and peripheral devices, and the shared resource controller 120 can configure the bus bar BUS ₁ to BUS ₁₈ according to the updated preset connection configuration CONF'. The centrally set up at least one busbar of the peripheral device busbars BUS ₁₀ to BUS ₁₈ is changed to be set to at least one computer host busbar, or the busbars BUS ₁ to BUS ₁₈ are originally set as the computer host busbars BUS ₁ to BUS. At least one busbar of ₉ is changed to be set to at least one peripheral device busbar.

For example, when the user wants to increase the number of computer hosts that the hardware resource sharing system 100 can support and reduce the number of peripheral devices that can be supported, the user can update the preset connection configuration CONF according to his needs. The shared resource controller 120 can change the part of the bus bar BUS ₁ to BUS ₁₈ originally set as the peripheral device bus bar BUS ₁₀ to BUS ₁₈ to be set as the host computer according to the updated preset connection configuration CONF'. The bus bar, for example, changes the bus bars BUS ₁₀ and BUS ₁₂ to be set to the computer host bus. Thereafter, the hardware resource sharing system 100 will obtain the message transmitted by the computer host to which it is coupled through the bus BUS ₁₀ and the BUS ₁₂ , and when the computer host performs the peripheral component quick interconnection bus scanning function, correspondingly The location returns the usage information of the peripheral devices corresponding to it.

On the other hand, if the user wants to reduce the number of computer hosts that the hardware resource sharing system 100 can support and increase the number of peripheral devices that can be supported, the shared resource controller 120 can configure CONF' according to the updated preset connection. The busbars BUS ₁ to BUS ₁₈ are originally set to be part of the busbars BUS ₁ to BUS _{9 and} the busbars are changed to be set as peripheral device busbars. For example, the busbars BUS ₇ and BUS _{9 are} changed to be set as peripheral device sinks. row. Thereafter, the hardware resource sharing system 100 will not obtain information about the host computer from the bus BUS ₇ to BUS ₉ . In order to enable the shared resource controller 120 to change the settings of the bus bars BUS ₁ to BUS ₁₈ according to the updated preset connection configuration CONF', in some implementations of the present invention, it may be necessary to add the hardware resource sharing system 100 Reset, so when you want to reset the bus BUS ₁ to BUS ₁₈ according to the updated preset connection configuration CONF', you can shut down or offline the computer hosts C ₁ to C ₉ to avoid the original operation. The computer host in the computer cannot operate normally because it cannot be connected to the corresponding peripheral device.

Through the hardware resource sharing system 100, different computer hosts can share the same peripheral device, and the shared resource controller 120 can not only dynamically adjust the connection between the host computer and peripheral devices, but also facilitate the user. The hot plugging method couples the peripheral device to the hardware resource sharing system 100, thereby not only increasing the efficiency of the hardware sharing, but also greatly improving the flexibility in use.
