A shared memory parallel processing system interconnected by a multi-stage network combines new system configuration techniques with special-purpose hardware to provide remote memory accesses across the network, while controlling cache coherency efficiently across the network. The system configuration techniques include a systematic method for partitioning and controlling the memory in relation to local verses remote accesses and changeable verses unchangeable data. Most of the special-purpose hardware is implemented in the memory controller and network adapter, which implements three send FIFOs and three receive FIFOs at each node to segregate and handle efficiently invalidate functions, remote stores, and remote accesses requiring cache coherency. The segregation of these three functions into different send and receive FIFOs greatly facilitates the cache coherency function over the network. In addition, the network itself is tailored to provide the best efficiency for remote accesses.

A high-speed method for maintaining a summary of thread activity reduces the number of remote-memory operations for an n processor, multiple node computer system from n2 to (2n−1) operations. The method uses a hierarchical summary of-thread-activity data structure that includes structures such as first and second level bit masks. The first level bit mask is accessible to all nodes and contains a bit per node, the bit indicating whether the corresponding node contains a processor that has not yet passed through a quiescent state. The second level bit mask is local to each node and contains a bit per processor per node, the bit indicating whether the corresponding processor has not yet passed through a quiescent state. The method includes determining from a data structure on the processor's node (such as a second level bitmask) if the processor has passed through a quiescent state. If so, it is then determined from the data structure if all other processors on its node have passed through a quiescent state. If so, it is then indicated in a data structure accessible to all nodes (such as the first level bitmask) that all processors on the processor's node have passed through a quiescent state. The local generation number can also be stored in the data structure accessible to all nodes. If a processor determines from this data structure that the processor is the last processor to pass through a quiescent state, the processor updates the data structure for storing a number of the current generation stored in the memory of each node.

A memory mapping unit requests allocation of a remote memory to memory mapping units of other processor nodes via a second communication unit, and requests creation of a mapping connection to a memory-mapping managing unit of a first processor node via the second communication unit. The memory-mapping managing unit creates the mapping connection between a processor node and other processor nodes according to a connection creation request from the memory mapping unit, and then transmits a memory mapping instruction for instructing execution of a memory mapping to the memory mapping unit via a first communication unit of the first processor node.

A non-uniform memory access (NUMA) computer system includes a remote node coupled by a node interconnect to a home node having a home system memory. The remote node includes a local interconnect, a processing unit and at least one cache coupled to the local interconnect, and a node controller coupled between the local interconnect and the node interconnect. The processing unit first issues, on the local interconnect, a read-type request targeting data resident in the home system memory with a flag in the read-type request set to a first state to indicate only local servicing of the read-type request. In response to inability to service the read-type request locally in the remote node, the processing unit reissues the read-type request with the flag set to a second state to instruct the node controller to transmit the read-type request to the home node. The node controller, which includes a plurality of queues, preferably does not queue the read-type request until receipt of the reissued read-type request with the flag set to the second state.

A method of selecting images from a plurality of images previously stored in a local digital memory, ordering services to be provided utilizing the images, and transferring such images over a channel to a remote digital memory where the services are to be provided includes storing a plurality of images in the local memory location along with corresponding thumbnail images and displaying at least a subset of the thumbnail images for viewing by a user. The user selects those images to be transferred after viewing the displayed thumbnail images and provides image identifiers for each selected image to be uploaded to the remote location and a service order which specifies the services to be provided utilizing such selected images. The remote location confirms the receipt of the service order. The images are transferred over the channel to the remote memory location at a suitable time for effective data transfer whereby the ordered services can be subsequently provided.

Memory demands of large-memory applications continue to remain one step ahead of the improvements in DRAM capacities of commodity systems. Performance of such applications degrades rapidly once the system hits the physical memory limit and starts paging to the local disk. A distributed network-based virtual memory scheme is provided which treats remote memory as another level in the memory hierarchy between very fast local memory and very slow local disks. Performance over gigabit Ethernet shows significant performance gains over local disk. Large memory applications may access potentially unlimited network memory resources without requiring any application or operating system code modifications, relinkling or recompilation. A preferred embodiment employs kernel-level driver software.

A memory module includes a memory hub that monitors utilization of the memory module and directs devices of the memory module to a reduced power state when the module is not being used at a desired level. System utilization of the memory module is monitored by tracking system usage, manifested by read and write commands issued to the memory module, or by measuring temperature changes indicating a level of device activity beyond normal refresh activity. Alternatively, measured activity levels can be transmitted over a system bus to a centralized power management controller which, responsive to the activity level packets transmitted by remote memory modules, direct devices of those remote memory modules to a reduced power state. The centralized power management controller could be disposed on a master memory module or in a memory or system controller.

A home node aware replacement policy for a cache chooses to evict lines which belong to local memory over lines which belong to remote memory, reducing the average transaction cost of incorrect cache line replacements. With each entry, the cache stores a t-bit cost metric (t≧1) representing a relative distance between said cache and an originating memory for the respective cache entry. Responsive to determining that no cache entry corresponds to an access request, the replacement policy selects a cache entry for eviction from the cache based at least in part on the t-bit cost metric. The selected cache entry is then evicted from the cache.

A data processing node has an inter-node messaging module including a plurality of sets of registers each defining an instance of a GET / PUT context and a plurality of data processing cores each coupled to the inter-node messaging module. Each one of the data processing cores includes a mapping function for mapping each one of a plurality of user level processes to a different one of the sets of registers and thereby to a respective GET / PUT context instance. Mapping each one of the user level processes to the different one of the sets of registers enables a particular one of the user level processes to utilize the respective GET / PUT context instance thereof for performing a GET / PUT action to a ring buffer of a different data processing node coupled to the data processing node through a fabric without involvement of an operating system of any one of the data processing cores.

The present invention relates to generating and executing a playlist in a scheduled programming environment. In one embodiment, a media content recommendation for select media content is received from a first entity. The select media content for the media content recommendation is then added to a playlist for a first user. The playlist will identify numerous media content items to be consumed at particular times, in a particular order, or a combination thereof. The playlist is provided to a content control function, which controls, either directly or remotely, a scheduled programming interface (SPI) device to execute the playlist. The SPI device effectively consumes the media content items of the playlist in an automated fashion. Consumption of the media content items may include presenting the media content to the first user via an audio or video monitor, recording the media content in local or remote storage, or a combination thereof.

Each node's memory controller may be configured to send and receive messages on a dedicated memory-to-memory interconnect according to the communication protocol and to responsively perform memory accesses in a local memory. The type of message sent on the interconnect may depend on which memory region is targeted by a memory access request local to the sending node. If certain regions are targeted locally, a memory controller may delay performance of a local memory access until the memory access has been performed remotely. Remote nodes may confirm performance of the remote memory accesses via the memory-to-memory interconnect.
