Patent ID: 11868823
Assignee: HUAWEI TECHNOLOGIES CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 8:
9. An interconnected computer system comprising:
a first Peripheral Component Interconnect Express (PCIe) fabric;
a second PCIe fabric;
a PCIe non-transparent bridge interconnecting the first PCIe fabric and the second PCIe fabric;
a first node cluster communicatively coupled to the first PCIe fabric;
a second node cluster communicatively coupled to the second PCIe fabric;
a shared single-access hardware resource coupled to one of the first PCIe fabric and the second PCIe fabric and remote from both the first node cluster and the second node cluster;
the first node cluster including a first memory local to the first node cluster and configured to store:
at least one first flag indicating a desire of the first node cluster to access the shared single-access hardware resource; and
a turn variable indicating which of the first node cluster and the second node cluster has access to the shared single-access hardware resource; and
the second node cluster including a second memory local to the second node cluster and configured to store at least one second flag indicating a desire of the second node cluster to access the shared single-access hardware resource, wherein the turn variable is separated from the second node cluster by at least one of the first PCIe fabric and the second PCIe fabric.
