Abstract: A computer system executing a learning process for generating a model includes: a computer having calculation cores; and a learning section. The learning section acquires performance information indicating performance characteristics of the calculation cores executing a positive sample calculation and the calculation cores executing a negative sample calculation, computes a maximum value of the number of negative samples in the negative sample calculation on the basis of the performance information, determines the number of the negative samples based on the maximum value, and generates the model by causing at least one of the calculation cores to execute the positive sample calculation using a predetermined number of pieces of training data to serve as positive samples in the training data, and by causing at least one of the calculation cores to execute the negative sample calculation using the determined number of the negative samples randomly selected from the training data.

Abstract: In some examples, a first node is able to communicate with one or more second nodes for participating in a consensus system. The first node may receive, from a computing device, a request to execute a first smart contract associated with a first blockchain. The first node may invoke execution of the first smart contract to cause the first smart contract to execute a transaction by reading at least a portion of transaction data from the first blockchain as a transaction result. Further, the first node may check whether a simulation indicator has been set, which indicates that an expiration time of the first smart contract has been reached. Based on determining that the first smart contract has the simulation indicator set, the first node refrains from writing the transaction result to the blockchain as a valid transaction result and sends the transaction result to the computing device.

Abstract: Method and apparatus creating test environments for blockchain systems involving recreating system configurations and state database without block data to set up staging environments for blockchain systems. The example implementations involve a function getting the latest config block and database files of state database from a production environment. Further, there is a function extracting system configurations from the received latest config block, replacing root certifying authority certificate(s) in the system configurations with the certificate(s) for the staging environment, creating a system configuration transaction and sending the system configuration transaction to the staging environment to reflect the system configurations. Further, there is a function extracting a list of states from database files, creating a transaction request message having the list of states and sending a transaction to the staging environment to load the states into the state database.

Abstract: An information processing device for reducing the number of times of interrupt notification for notifying completion of execution of input/output instruction and lightening a load of interrupt processing is described. The information processing device prescribes that a driver checks a completion state of a preceding input/output instruction after issuance of the input/output instruction. An issuing timing of the input/output instruction is considered to be a polling timing for checking the completion state of the preceding input/output instruction. Before the input/output device transmits interrupt notification to a CPU, the input/output device sets a timer to stand by for a prescribed time. A processing unit which resets the timer and extends the standby time by a prescribed time in a case where notification that a subsequent input/output instruction is issued arrives from a driver to the input/output device during the time is additionally provided to the input/output device.

Abstract: A token management system records consent of an end user who entrusts operation of a token to a blockchain network participant organization deploying a token based on a request from an end user. The system includes a token registration unit, a user management unit, a token management unit, a policy management unit, and a life cycle management unit. The token registration unit registers a test result, an electronic signature, and a hash of a token program in the memory device as repository information, the electronic signature and the hash being confirmation evidence. The user management unit records consent of the end user, as a trail, to entrust operation of the token to a virtual organization, and registers the consent in the memory device. The token management unit records consent of the end user, as a trail, to deploy the token, and registers the consent in the memory device.
