A communications device that includes a requester and a responder may support multiple transaction classes, including an ordered transaction class, while maintaining a bifurcated requester/responder architecture. Before a responder has a non-posted transaction response to transmit on an interconnect, it receives an indication from the requester that there is not a pending posted transaction on the interconnect.

Examples include a ticketing system for managing performance of computer services. The ticketing system includes a ticket database to store a plurality of tickets, each ticket defining a job to be performed on a computing system, and a master to create a ticket, store the ticket in the ticket database, and update the ticket. The ticketing system includes a scheduler to determine whether to create the ticket based at least in part on a set of conditions, and to request the master to create the ticket when the ticket is to be created, and a worker to get the ticket from the master, perform the job defined by the ticket, and request the master to update the ticket with a status of the ticket. The ticketing system includes a supervisor to request the master to find a stale ticket, and, if found, to request the worker to abort performance of the job defined by the stale ticket.

An accelerated transaction processing apparatus includes a memory for storing one or more instructions, a communication interface for communicating with a blockchain network, and a processor. The processor is configured to determine whether the blockchain network is in a congested state based on monitoring information about the blockchain network, adjust a batch size based on a result of the determination, and perform batch processing for one or more individual transactions using the adjusted batch size.

A method of ensuring atomicity of transactions across a plurality of active hosts in a distributed environment, is provided. The method generally includes receiving, from a client, a second request to commit a second transaction subsequent to receiving a first request to commit a first transaction; assigning a second prepare identifier (ID) to the second transaction, wherein the second prepare ID assigned to the second transaction is greater than a first prepare ID assigned to the first transaction; transmitting, to the plurality of active hosts, instructions to prepare for committing the second transaction, the instructions including the second prepare ID; receiving, from each host, an acknowledgement indicating successful preparation for committing the second transaction; and transmitting, to the plurality of active hosts, instructions to commit the second transaction prior to receiving, from each host, an acknowledgement indicating successful preparation for committing the first transaction.

An example of communicating transaction data between a first service and a second service includes receiving transactions of first service, and processing the received transactions and storing the results in a database of the first service. For at least some of the received transactions, corresponding transaction messages are produced for processing by the second service, and tracking that each of the transaction messages is provided to a message queue. The transaction messages are received from the message queue and are processed using the second service, and the results are stored in a database of the second service. When there are duplicate transaction messages received from the message queue, the database of the second service only stores the results of one of the duplicate transaction messages.

An apparatus for verifying validity of transactions and/or blocks includes: a processor, a memory, and a communication device, wherein the processor executes a program stored in the memory to perform: verifying validity of a predetermined number of transactions and/or blocks among a plurality of transactions and/or blocks received from at least one peer in a blockchain system; and determining an increase or a decrease of the predetermined number according to a verification result of the predetermined number of transactions and/or blocks is provided.

Systems and methods provide reception of a call to a first function, determination of a first configuration file associated with the first function, the first configuration file indicating a primary function, a secondary function and a relationship between a first property of the primary function and a second property of the secondary function, calling of the primary function and reception of a corresponding first result set, calling of the secondary function, the call to the secondary function including a filter on the second property based on values of the first result set associated with the first property, reception of a second result set corresponding to the call to the secondary function, generation of a composed result set based on the first result set, the second result set, and the relationship, and return of the composed result set in response to the call to the first function.

Provided are a method and apparatus for operating a blockchain system, a device and a storage medium. The method is described below. To-be-processed blockchain data is acquired through a kernel engine of a blockchain system. The to-be-processed blockchain data is processed through the kernel engine, and a kernel component interface provided by a component adaptor is called during the processing process of the to-be-processed blockchain data to call a kernel component.

A method for selecting an AI solution for an automated robotic process including receiving at least one functional media including information indicative of brain activity by a human engaged in a task of interest, analyzing the functional media, identifying an activity level in at least one brain region, identifying a brain region parameter and an activity parameter; identifying an action parameter based in part on the brain region parameter or the activity parameter; and selecting a component of the AI solution in part on the brain region parameter, the activity parameter, or the action parameter.

Disclosed in some examples are systems, methods, devices, and machine-readable mediums to detect and terminate programmable atomic transactions that are stuck in an infinite loop. In order to detect and terminate these transactions, the programmable atomic unit may use an instruction counter that increments each time an instruction is executed during execution of a programmable atomic transaction. If the instruction counter meets or exceeds a threshold instruction execution limit without reaching the termination instruction, the programmable atomic transaction may be terminated, all resources used (e.g., memory locks) may be freed, and a response may be sent to a calling processor.
