Title:
RDMA EVENT MANAGEMENT METHODS, AND DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/088268
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are RDMA event management methods, and a device and a storage medium. In the embodiments of the present application, a user mode event management instance for event notification is additionally set between an RDMA application and an RDMA device, and on the basis of the user mode event management instance, during an event notification process for the RDMA application, a CPU hardware resource for performing completion event notification to the RDMA application can wait for the occurrence of a completion event in a low-power-consumption state, such that the power consumption is reduced; and when the completion event occurs, the RDMA device can "wake up" the CPU hardware resource in a user mode, and after the CPU hardware resource is woken up, the RDMA application can be directly notified of the occurrence of the completion event. The whole process does not require the involvement of a kernel mode, such that context switching between the kernel mode and the user mode is not required, thereby shortening the path and period of event notification, reducing a network communication delay of the RDMA application, and improving the application performance of RDMA.
