摘要： Provided are systems, methods, and computer-readable medium for enabling sharing of a multi-channel packet processor by multiple processes executing on a network device. The network device can include a memory management unit, configured to include an address map. The address map can include a reserved portion. The virtual machine can allocate a guest portion in the address map, where the guest portion is allocated in a part of the address map that does not include the reserved portion. A first channel from the packet processor can be assigned to the guest portion, and the virtual machine can use the first channel to receive packets. The reserved portion can be assigned to a host process executing on the network device. A second channel from the packet processor can be assigned to the reserved portion. The host process can transmit packets to the network using the second channel.

摘要： A distributed storage system (100) includes memory hosts (110), each including non-transitory memory (114) and a network interface controller (116) in communication with the memory and servicing remote direct memory access requests (122) from clients (120). The memory receives a data transfer rate (313) from each client in communication with the memory host through remote direct memory access. Each memory host also includes a data processor (112) in communication with the memory and the network interface controller. The data processor executes a host process (118) that reads each received client data transfer rate, determines a throttle data transfer rate (317) for each client, and writes each throttle data transfer rate to non-transitory memory accessible by the clients through remote direct memory access.

摘要： In one example, a memory network may control access to a shared memory that is by multiple compute nodes. The memory network may control the access to the shared memory by receiving a memory access request originating from an application executing on the multiple compute nodes and determining a priority for processing the memory access request. The priority determined by the memory network may correspond to a memory address range in the memory that is specifically used by the application.

摘要： The present invention provides a lock management solution in a cluster, where the cluster includes a client and a lock server, the lock server includes an interface card and a memory, the memory stores a read lock request queue recording an identifier of a client that waits for a read lock or obtains a read lock, the memory further stores a write lock request queue recording an identifier of a client that waits for a write lock or obtains a write lock, and the memory further includes a read lock allocation count and a write lock allocation identifier, where the read lock allocation count is used to record an allocated read lock, and the write lock allocation identifier is used to indicate whether a write lock has been allocated. The client communicates with the interface card of the lock server by using the RDMA protocol to perform a lock operation.

摘要： A method for storage includes storing multiple memory pages in a memory of a first compute node. Using a second compute node that communicates with the first compute node over a communication network, duplicate memory pages are identified among the memory pages stored in the memory of the first compute node by directly accessing the memory of the first compute node. One or more of the identified duplicate memory pages are evicted from the first compute node.

摘要： A memory appliance system is described that includes a memory unit comprising a memory unit controller and a plurality of memory devices. A reconfigurable memory structure is stored in the plurality of memory devices, wherein the memory structure comprises a plurality of variably sized containers. Each container of data includes metadata, payload, and relationship information that associates a corresponding container with one or more other containers stored in the memory structure. The controller is data structure aware such that the controller is configured to traverse the memory structure and perform operations on the memory structure based on the metadata and relationship information.

摘要： A parallel processing system includes a plurality of computers accessibly connected through a network, and distributedly executing a plurality of processes. Each of the plurality of computers is composed of an operation processing unit configured to execute an allocated process, a local memory group having a first area and a second area and an I/O control circuit. The operation processing unit executes the allocated process by using the first area as an access destination in a first period and, and executes the allocated process by using the second area as the access destination in a second period subsequent to the first period. The I/O control circuit is composed of an updating section configured to update data stored in the local memory group to the latest data by carrying out communication among the computers. The updating section updates the data stored in the first area in the second period.
