Abstract: In one embodiment, a block data transfer interface employing offload data transfer engine in accordance with the present description includes an offload data transfer engine executing a data transfer command set to transfer a block of data in a transfer data path from a source memory to a new region of a destination memory, wherein the transfer data path bypasses a central processing unit to minimize or reduce involvement of the central processing unit in the block transfer. In response to a successful transfer indication, a logical address is re-mapped to a physical address of the new region of the destination memory, instead of a physical address of the original region of the destination memory. In one embodiment, the re-mapping is performed by a central processing unit. In another embodiment, the re-mapping is performed by the offload data transfer engine. Other aspects are described herein.

Abstract: An extension of node architecture and proxy requests enables a node to expose memory computation capability to remote nodes. A remote node can request execution of an operation by a remote memory computation resource, and the remote memory computation resource can execute the request locally and return the results of the computation. The node includes processing resources, a fabric interface, and a memory subsystem including a memory computation resource. The local execution of the request by the memory computation resource can reduce latency and bandwidth concerns typical with remote requests.

Abstract: Examples relate to a non-transitory, computer-readable medium, method, and computer system for prefetching data during executing of a computer program. The non-transitory, computer-readable medium comprises machine-readable instructions that, when the program code is executed on a processor, causes the processor to pre-fetch to a processor cache, using data transfer offloading circuitry of the processor, data being accessed by an application program from a main memory of the computer system, and to execute the computer program using the pre-fetched data that is stored in the processor cache.

Abstract: A processor includes an instruction decoder to receive an instruction to perform a machine check operation, the instruction having a first operand and a second operand. The processor further includes a machine check logic coupled to the instruction decoder to determine that the instruction is to determine a type of a machine check bank based on a command value stored in a first storage location indicated by the first operand, to determine a type of a machine check bank identified by a machine check bank identifier (ID) stored in a second storage location indicated by the second operand, and to store the determined type of the machine check bank in the first storage location indicated by the first operand.
