Abstract: The disclosed embodiments relate to a computing system that facilitates performing prefetching for scatter/gather operations. During operation, the system receives a scatter/gather prefetch instruction at a processor core, wherein the scatter/gather prefetch instruction specifies a virtual base address, and a plurality of offsets. Next, the system performs a lookup in a translation-lookaside buffer (TLB) using the virtual base address to obtain a physical base address that identifies a physical page for the base address. The system then sends the physical base address and the plurality of offsets to a cache. This enables the cache to perform prefetching operations for the scatter/gather instruction by adding the physical base address to the plurality of offsets to produce a plurality of physical addresses, and then prefetching cache lines for the plurality of physical addresses into the cache.

Abstract: A system and method for transferring data and messages between nodes in a cluster is disclosed. Each node in the cluster is a separate physical domain but is connected to other nodes in the cluster through point-to-point high speed links. Each side of a link is coupled to a coprocessor which facilitates the movement of data between and among the nodes. Because each physical domain is separate from any other domain, the coprocessor in a physical domain uses a certificate, called and RKey, to obtain permission to transfer data to another physical domain. When an RKey is received from another physical domain, the coprocessor in the receiving domain validates the key and obtains the physical addresses associated with the key so that it can provide or accept the remote data. Data transfers between pairs of remote nodes in the cluster are permitted as well.

Abstract: A system and method implementing revocable secure remote keys is disclosed. A plurality of indexed base secrets is stored in a register of a coprocessor of a local node coupled with a local memory. When it is determined that a selected base secret expired, the base secret stored in the register based on the base secret index is changed, thereby invalidating remote keys generated based on the expired base secret. A remote key with validation data and a base secret index is received from a node requesting access to the local memory. A validation base secret is obtained from the register based on the base secret index. The coprocessor performs hardware validation on the validation data based on the validation base secret. Hardware validation fails if the base secret associated with the base secret index has been changed in the register of the selected coprocessor.

Abstract: Techniques for processing a query are provided. One or more operations that are required to process a query are performed by a coprocessor that is separate from a general purpose microprocessor that executes query processing software. The query processing software receives a query, determines one or more operations that are required to be executed to fully process the query, and issues one or more commands to one or more coprocessors that are programmed to perform one of the operations, such as a table scan operation and/or a lookup operation. The query processing software obtains results from the coprocessor(s) and performs one or more additional operations thereon to generate a final result of the query.
