20100169501 | Massage communication techniques - A network protocol unit interface is described that uses a message engine to transfer contents of received network protocol units in message segments to a destination message engine. The network protocol unit interface uses a message engine to receive messages whose content is to be transmitted in network protocol units. A message engine transmits message segments to a destination message engine without the message engine transmitter and receiver sharing memory space. In addition, the transmitter message engine can transmit message segments to a receiver message engine by use of a virtual address associated with the receiver message and a queue identifier, as opposed to a memory address. | 07-01-2010 |
20100169528 | Interrupt technicques - Techniques are described that can be used by a message engine to notify a core or hardware thread of activity. For example, an inter-processor interrupt can be used to notify the core or hardware thread. The message engine may generate notifications in response to one or more message received from a transmitting message engine. Message engines may communicate without sharing memory space. | 07-01-2010 |

20090006668 | Performing direct data transactions with a cache memory - In one embodiment, the present invention includes a method for receiving data from a producer input/output device in a cache associated with a consumer without writing the data to a memory coupled to the consumer and storing the data in a cache buffer until ownership of the data is obtained, and then storing the data in a cache line of the cache. Other embodiments are described and claimed. | 01-01-2009 |
20090089505 | STEERING DATA UNITS TO A CONSUMER - A computer system may comprise a second device operating as a producer that may steer data units to a first device operating as a consumer. A processing core of the first device may wake-up the second device after generating a first data unit. The second device may generate steering values after retrieving a first data unit directly from the cache of the first device. The second device may populate a flow table with a plurality of entries using the steering values. The second device may receive a packet over a network and store the packet directly into the cache of the first device using a first steering value. The second device may direct an interrupt signal to the processing core of the first device using a second steering value. | 04-02-2009 |

20100042579 | GENERATING AND/OR RECEIVING, AT LEAST IN PART, AT LEAST ONE DATA ACCESS REQUEST - In an embodiment, an apparatus is provided that may include circuitry to generate, at least in part, and/or receive, at least in part, at least one request to access at least one portion of data. The at least one request may indicate, at least in part, at least one subset of the at least one portion of the data that is of relatively higher importance than one or more other subsets of the at least one portion of the data that are of relatively lower importance. The at least one request may be to request, at least in part, that the at least one subset be accessed prior to the one or more other subsets are accessed. The at least one request may be comprised, at least in part, in at least one packet in accordance with a protocol that permits variable packet size. | 02-18-2010 |

20090089454 | Network packet payload compression - Methods and apparatus relating to network packet payload compression/decompression are described. In an embodiment, an uncompressed packet payload may be compressed before being transferred between various components of a computing system. For example, a packet payload may be compressed prior to transfer between network interface cards or controllers (NICs) and storage devices (e.g., including a main system memory and/or cache(s)), as well as between processors (or processor cores) and storage devices (e.g., including main system memory and/or caches). Other embodiments are also disclosed. | 04-02-2009 |
