Abstract: Systems and methods for a controller including controller memory and logic are presented herein. The logic is configured to control access to a persistent storage media and, in response to one or more commands, the logic determines an intermediate parity value based on a first parity calculation, and using the intermediate parity value determines a final parity value based on the intermediate parity value and a second parity calculation. Determining the intermediate parity value includes sending a uni-directional command to read an old data value from an address indicated in the uni-directional command, perform an exclusive-or operation on the old data value and a new data value indicated in the uni-directional command to determine the intermediate parity value and store, in the persistent storage media, the intermediate parity value at a location associated to an index indicated in the uni-directional command.

Abstract: An embodiment of an electronic apparatus may include one or more substrates, and logic coupled to the one or more substrates, the logic to control local access to a persistent storage media and, in response to one or more commands, to determine an intermediate parity value based on a first local parity calculation, locally store the intermediate parity value, and determine a final parity value based on the intermediate parity value and a second local parity calculation. Other embodiments are disclosed and claimed.

Abstract: Systems, apparatuses, and methods provide for a memory controller to manage cache evictions and/or insertions in a two level memory controller mode that uses a dynamic random access memory as a transparent cache for a persistent memory. For example, a memory controller includes logic to map cached data in the dynamic random access memory to an original address of copied data in the persistent memory. The cached data in the dynamic random access memory is tracked as to whether it is dirty data or clean data with respect to the copied data in the persistent memory. Upon eviction of the cached data from the dynamic random access memory, a writeback of the cached data that has been evicted to the persistent memory is bypassed when the cached data is tracked as dirty data.

Abstract: Techniques and mechanisms for communicating compiled software instructions via a network, wherein the compiled instructions are to execute a kernel process of a network device. In an embodiment, a first node of a network receives a kernel source code from a second node of the network.
