The embodiments of the present disclosure disclose a page swap method, device, and electronic device. In the page swap method described in the present disclosure, the swap-out overhead of the hybrid storage structure can be reduced by: (1) using a per-thread page table and TLB shootdown operation to track the page mapping cache and reduce the TLB shootdown overhead; (2) through the operating system kernel and the programming language runtime with garbage collection and lightweight concurrency, the swap-out is regarded as a lightweight thread scheduled by the programming language runtime with garbage collection and lightweight concurrency to perform the swap-out asynchronously.

The present invention relates to a trusted execution method and system for blockchain computing-intensive transactions. The computing nodes under the chain of the present invention execute transaction calculations and package the calculation tree and the calculation results together and publish them on the blockchain; during the publicity period of the transaction results, all computing nodes monitor and compare whether the calculation results on the blockchain are the same as the local results, and if they are different, a transaction objection is initiated; the publisher of the calculation results receives the transaction objection information and publishes the variable status that is objected to in its own calculation tree; the consensus node arbitrates the correctness of the specified variable status and takes the final honest one as the latest result of the transaction; according to the availability status of the computing-intensive transaction, it is checked whether the transaction result meets the confirmation condition, and the relevant transaction results that do not meet the confirmation condition are discarded. A large number of transaction calculations are executed on a small number of nodes under the chain, thereby reducing the calculation overhead of the blockchain node when verifying the transaction, and preventing the long execution time of the computing-intensive transaction from blocking the blockchain.

This application provides a source code generation method and apparatus. The method includes: determining target features based on a first fragment, wherein the first fragment includes one or more codes input by a user before a first moment, and the target features are used to indicate code attributes of the codes in the fragment; generating multiple candidate fragments; and selecting a second fragment from the multiple candidate fragments based on the target features, wherein the features of the second fragment have the highest similarity to the target features among the features of the multiple candidate fragments. The target features are obtained based on the source code input by the user and serve as the user's sequence preference. The source code suggestions provided to the user are generated based on the user's sequence preference. In other words, the generated source code is related to the source code input by the user. Therefore, the accuracy of the generated source code can be improved.

We generally describe an optical demultiplexer, comprising: an electro-optic modulator for changing the polarization of an optical pulse having a first polarization and passing through the electro-optic modulator from the first polarization to a second polarization when the electro-optic modulator is in a first state; a first mirror and a second mirror, wherein the electro-optic modulator is located in an optical track between the first mirror and the second mirror, such that an optical pulse traveling in the optical track between the first mirror and the second mirror passes through the electro-optic modulator, wherein the first mirror and the second mirror are located in the optical demultiplexer, such that an optical pulse traveling in the optical track between the first mirror and the second mirror passes through the electro-optic modulator. The pulse, during each round of travel between the first and second mirrors, is shifted perpendicular to the propagation direction of the light pulse between the first and second mirrors; and a first polarization beamsplitter is located in the optical track between the first mirror and the electro-optic modulator, wherein the first polarization beamsplitter is configured to: transmit a light pulse having a first polarization and reflect a light pulse having a second polarization to remove a light pulse having a second polarization from the optical track between the first and second mirrors, wherein the first polarization beamsplitter is configured to reflect light pulses that are shifted perpendicular to each other's propagation direction onto different, respective output tracks.
