摘要： A memory leveling system updates physical memory blocks, or blocks, to maintain generally even wear. The system maintains an update count for each block, incrementing a wear level count when the update count reaches a wear level threshold. The system compares a wear level of blocks to determine whether to update a block in place or move data on the block to a less-worn physical block. The system groups the blocks into wear level groups identified by a common wear level to identify blocks that are being worn at a faster or slower than average rate. If an empty block count of a least worn group drops below a threshold, the system moves data from one of the blocks in the least worn group to an empty block in a most worn group.

摘要： A packet classifier within a network adapter detects an application packet header belonging to a packet in a data stream associated with an application that uses a network protocol, such as TCP/IP, SNA or IPX. Offsets included within the application header are identified and a plurality of registers is loaded with the identified offsets. Each of a plurality direct data placement patterns are masked with contents of the loaded registers. Each direct data placement pattern is associated with an application packet header and includes a corresponding I/O context. Additionally, each direct data placement pattern includes a corresponding connection path for direct placement of a payload corresponding to the detected application header in a memory that is utilized by the application.

摘要： Conflicts are resolved between competing nodes in a multi-node communications network. After a first node in the network requests an initiation of communications with a target node, the requesting node may simply initiate the requested communications with the target node if the target node is not busy. If the first node determines that the target node is busy, it proceeds to resolve the conflict. Namely, the first node repeats the process of waiting for a first delay then requesting initiation of communications with the target node. After each unsuccessful attempt, the first delay is successively increased. As an example, the delay may be increased exponentially, with a controlled randomness added. After a or more queued messages to other nodes. Following this, the first node performs another sequence to initiate communications with the target node, successively increasing the delay between unsuccessful attempts, as before. After a predetermined number of unsuccessful passes through the foregoing routine, the first node proceeds to take appropriate action, such as initiating an error recovery routine, sending the message via different hardware components, or issuing an error message.

摘要： A method enables a host processor, which employs variable length (VL) records, to transparently communicate with disk storage which employs fixed length (FL) sectors for storage of the VL records. The method comprises the steps of: a) deriving a first control data structure for an update VL record, the first control data structure including information describing segments of the update VL record; b) determining an FL sector wherein an old VL record commences that corresponds to the update VL record; c) if the old VL record commences at other than a sector break of the FL sector, deriving a second control data structure for a portion of a prior VL record that immediately precedes the old VL record and a third control data structure for the old VL record; d) substituting in the third control data structure, information regarding update segments of the update VL record from the first control data structure; and recording in the FL sector determined in c), data indicated by the second control data structure and at least a portion of the update VL record, through use of the third control structure as altered in d).

摘要： A multi-nodal data processing system includes a plurality of processing nodes, each node connected to plural other nodes by bidirectional data links. Each node comprises receivers for receiving messages on bidirectional data links and transmitters for transmitting messages on bidirectional data links. Each node records child nodes to which a message was transmitted and is further adapted to transmit a lock-up message received from a child node to a parent node, the lock-up message indicating a successful establishment of a message signal path to a destination node. Each node further is adapted to transmit a link cancel signal to another node to close the link in the event of an unsuccessful message transfer attempt over the link. Each node inhibits transmission of a lock-up signal to a parent node until link cancel signals have been received from all child nodes (other than a node from which a lock-up signal was received). A source node (where a message originates) continues transmission of its message, even before a lock-up signal has been received. The destination node which originates the lock-up message terminates a bidirectional data link by an end-of-session signal when it has received an entire message.

摘要： An apparatus for dynamically allocating memory includes a processor, a free buffer pool memory and a control memory which stores control block data structures. The control block data structures enable a segmentation of the free buffer pool memory into a series of free buffer pools, each free buffer pool comprising plural identical size buffers, each succeeding free buffer pool including a larger buffer size than a preceding free buffer pool. A selection size parameter for a given free buffer pool is a value that is larger than the buffer size comprising the given free buffer pool, but less than a next larger buffer size in the next of the series of free buffer pools. A memory allocation procedure responds to a request from an executing procedure for allocation of buffer space by: (i) allocating a buffer from a free buffer pool memory whose associated selection size parameter is a next larger value than the buffer space that was requested; (ii) determining a difference between the allocated buffer size and the requested buffer space to find an unfulfilled amount of the requested buffer space; (iii) allocating a buffer from a free buffer pool memory whose selection size parameter is a next larger value, among selection size parameters, than the unfulfilled amount; and (iv) repeating ii and iii until the memory allocation procedure determines that there is no unfulfilled amount of the requested buffer space. The apparatus further includes "quickcell" memory which is allocated without use of control block data structures.
