摘要： A method and system are provided for transferring data in a networked system between a local memory in a local system and a remote memory in a remote system. A RDMA request is received and a first buffer region is associated with a first transfer operation. The system determines whether a size of the first buffer region exceeds a maximum transfer size of the networked system. Portions of the second buffer region may be associated with the first transfer operation based on the determination of the size of the first buffer region. The system subsequently performs the first transfer operation.

摘要： Embodiments of the invention describe systems, apparatuses and methods that enable sharing Remote Direct Memory Access (RDMA) device hardware between a host and a peripheral device including a CPU and memory complex (alternatively referred to herein as a processor add-in card). Embodiments of the invention utilize interconnect hardware such as Peripheral Component Interconnect express (PCIe) hardware for peer-to-peer data transfers between processor add-in cards and RDMA devices. A host system may include modules or logic to map memory and registers to and/or from the RDMA device, thereby enabling I/O to be performed directly to and from user-mode applications on the processor add-in card, concurrently with host system I/O operations.

摘要： One embodiment provides Subnet administrator (SA) proxy logic to be executed by a computer network node. The SA proxy logic includes provider logic that includes path record information of an associated subnet in communication with the computer network node; and provider interface logic to receive an address resolution request from at least one application that includes partial address information. The provider interface logic is also to determine at least one local port of the computer network node to enable packet routing associated with the address resolution request. The provider logic is also to determine at least one subnet associated with the address resolution request. The provider interface logic is also to determine at least one provider logic to utilize to obtain the path record information for at least one subnet associated with the address resolution request. The provider interface logic is also to generate an address resolution response that includes a resolved address, that includes the path record information, and the identity of at least one local port to enable the at least one application to route data packets through the at least one determined subnet.
