A storage system comprises a plurality of storage subsystems. One storage subsystem as a succeeding subsystem is configured to receive and store one or more blocks of data from another storage subsystem as a preceding subsystem. Each block of data has an associated sequence number in ascending order. The memory in each storage subsystem includes a queue to store the blocks of data and a sequence number associated with each block of data, a record to store a last sequence number associated with a last block of data received by the queue, and a table to store last sequence numbers stored in the last sequence number record gathered from each succeeding storage system. In some embodiments, a smallest last sequence number is determined from the last sequence numbers associated with the blocks of data in the storage subsystems. Blocks of data in the queue of each storage subsystem having associated sequence numbers less than or equal to the determined smallest last sequence number are deleted. In case of a failure of one or more storage subsystems, blocks of data are copied from the surviving storage subsystem having associated sequence numbers higher than the last sequence number of other surviving storage subsystems.

A high-performance distributed ledger and transaction computing network fabric over which large numbers of transactions (involving the transformation, conversion or transfer of information or value) are processed concurrently in a scalable, reliable, secure and efficient manner. In one embodiment, the computing network fabric or “core” is configured to support a distributed blockchain network that organizes data in a manner that allows communication, processing and storage of blocks of the chain to be performed concurrently, with little synchronization, at very high performance and low latency, even when the transactions themselves originate from distant sources. This data organization relies on segmenting a transaction space within autonomous but cooperating computing nodes that are configured as a processing mesh. Each computing node typically is functionally-equivalent to all other nodes in the core. The nodes operate on blocks independently from one another while still maintaining a consistent and logically-complete view of the blockchain as a whole. According to another feature, safe and performant transaction processing is provided using an optimistic concurrently control that includes a collision detection and undo mechanism.

In a drive of a stepping motor, an electromotive force is generated on the coil of a motor with a sinusoidal wave having the same period as an energization period by smoothly rotating a rotor with microstep driving, and an induced power is stably detected by detecting the electromotive force at the zero cross of driving current. The detection around the current zero cross makes it possible to shorten a detection section, form a driving waveform with few distortions, and perform driving with a driving waveform as in an ordinary micro step. Thus a circuit is provided which is aimed at reducing noise, vibrations, and loss of synchronization, and increasing current consumption efficiency in the determination of stop.

The present invention discloses a system and a methodology for enhancing performance during wireless communications by reducing system latency, MIPS requirements and power consumption. The present invention discloses a system and method of wireless data communication in which part of upper layer stack processing is performed on a controller to relieve a host processor of some data intensive operations. After the initial connection establishment phase in which the controller retrieves certain information required for data transmission and stores the same locally, the data source provides data directly to the controller without routing the data through the host. The host is relieved of the data processing that needs to be done while the data is being transferred. Hence, the overall latency of the system is improved because of the optimal routing of data traffic. The host can even go to lower power modes while the controller is performing the data operations on behalf of the upper layer stack thereby saving power consumption of the overall system.

A method, a system, an apparatus, and a computer program product are presented for reducing synchronization waits when unique sequential identifiers are being allocated for transactions committed to a database that are occurring in a multi-threaded server environment. A transactional object containing an identifier data item is created for a transaction in an object-oriented environment. A pre-process object is then generated that contains the transactional object; when subsequently processed, the pre-process object allocates a sequential identifier value for the identifier data item. The pre-process object is added to a list of pre-process objects that are to be processed prior to completing the transaction, such as committing the transaction to a database. After some initial business logic processing, a commit operation for the transaction is commenced during which the pre-process object is processed, thereby allocating a sequential identifier value for the identifier data item just prior to committing the transaction.
