Abstract: Method and system for performing data movement operations is described herein. One embodiment of a method includes: storing data for a first memory address in a cache line of a memory of a first processing unit, the cache line associated with a coherency state indicating that the memory has sole ownership of the cache line; decoding an instruction for execution by a second processing unit, the instruction comprising a source data operand specifying the first memory address and a destination operand specifying a memory location in the second processing unit; and responsive to executing the decoded instruction, copying data from the cache line of the memory of the first processing unit as identified by the first memory address, to the memory location of the second processing unit, wherein responsive to the copy, the cache line is to remain in the memory and the coherency state is to remain unchanged.

Abstract: Embodiment of this disclosure provides a mechanism to use a portion of an inactive processing element's private cache as an extended last-level cache storage space to adaptively adjust the size of shared cache. In one embodiment, a processing device is provided. The processing device comprising a cache controller is to identify a cache line to evict from a shared cache. An inactive processing core is selected by the cache controller from a plurality of processing cores associated with the shared cache. Then, a private cache of the inactive processing core is notified of an identifier of a cache line associated with the shared cache. Thereupon, the cache line is evicted from the shared cache to install in the private cache.

Abstract: Particular embodiments described herein provide for an electronic device that can be configured to group two or more small packets that are to be communicated to a common destination, where the two or more packets are grouped together in a queue dedicated to temporarily store small packets that are to be communicated to the common destination, coalesce the small packets into a coalesced packet, where the coalesced packet is a network packet, and communicate the coalesced packet to the common destination. In an example, the size of a small packet is a packet that is smaller than the network packet. In another example, the size of a small packet is less than half the size of the network packet.
