摘要： Supporting multiple graphics processing units (GPUs) comprises a first path coupled to a north bridge device (or a root complex device) and a first GPU, which may include a portion of the first GPU's total communication lanes. A second communication path may be coupled to the north bridge device and a second GPU and may include a portion of the second GPU's total communication lanes. A third communication path may be coupled between the first and second GPUs directly or through one or more switches that can be configured for single or multiple GPU operations. The third communication path may include some or all of the remaining communication lanes for the first and second GPUs. As a nonlimiting example, the first and second GPUs may each utilize an 8-lane PCI express communication path with the north bridge device and an 8-lane PCI express communication path with each other.
摘要翻译：支持多个图形处理单元（GPU）包括耦合到北桥设备（或根复杂设备）的第一路径和可以包括第一GPU总通信线路的一部分的第一GPU。第二通信路径可以耦合到北桥设备和第二GPU，并且可以包括第二GPU的总通信线路的一部分。第三通信路径可以直接地耦合在第一和第二GPU之间，或者通过一个或多个可以被配置用于单个或多个GPU操作的交换机。第三通信路径可以包括用于第一和第二GPU的剩余通信线路中的一些或全部。作为非限制性示例，第一和第二GPU可以各自利用与北桥设备的8通道PCI快速通信路径和彼此之间的8通道PCI快速通信路径。

摘要： A system and method for supporting multiple graphics processing units (GPUs) includes a first communication path coupled to a root complex device and a first connection point of a first GPU. A second communication path is coupled to the root complex device and a first set of switches. The first set of switches is configured to route communications between the root complex device to either a second connection point of the first GPU via a second set of switches or to a first connection point of a second GPU. The second set of switches is coupled to a second connection point of the first GPU. The second set of switches is configured to route communications to and from the second connection point of the first GPU and to either the root complex device via the first set of switches or to a second connection point of the second GPU.
