Abstract: Method and device for data transmissions using RDMA. The present invention is implemented between a first entity using a first data structure type and a second entity using a second data structure type over a third entity. The third entity is coupled to a table caching fingerprints of first data structures of the first data structure type and second data structures of the second data structure type associated therewith. A certain first data structure and the second data structure associated therewith represent a certain, identical RDMA function call. A first data structure representing a certain RDMA function call is sent from the first entity to the third entity; the fingerprint for the sent first data structure is determined; a second data structure associated with the determined fingerprint is looked up in the table; and the looked up second data structure is sent to the second entity.

Abstract: A computer-implemented method, system, and article of manufacture for data communication between a requester and a responder in a remote direct memory access (RDMA) network, where each of the requester and the responder is an RDMA-enabled host of the network. The method includes: sending a request for the responder to provide data, where the request includes a mapped steering tag that is obtained by mapping a set of memory buffers of the requester onto a single representation that allows for identifying each of the memory buffers of the set; and receiving the requested data together with the mapped steering tag and assigning the data being received to the memory buffers of the set consistently with the mapping.

Abstract: A method of distributed memory access in a network, the network including a plurality of distributed compute elements, at least one control element and a plurality of distributed memory elements, wherein a data element is striped into data segments, the data segments being imported on at least a number of the distributed memory elements by multiple paths in the network, includes receiving, by a requesting element, credentials including an access permission for accessing the number of distributed memory elements and location information from the control element, the location information indicating physical locations of the data segments on the number of distributed memory elements; and launching, by the requesting element, a plurality of data transfers of the data segments over the multiple paths in the network to and/or from the physical locations.
