The invention discloses a memory scheduling method, system and product based on a separated memory system, and relates to the technical field of memory scheduling. The method comprises the following steps: determining target memory equipment accessed by a current task according to demand parameters of the current task and actual operation parameters of a separated memory system, and before actually deploying the memory equipment, executing the target memory equipment according to the demand parameters of execution of the current task; the target memory device to be accessed by the current task is preliminarily determined corresponding to the demand parameters of different tasks and the actual operation parameters of the separated memory system. In order to reduce the access time delay corresponding to the current task, the access cost of the current target memory device is estimated through the historical call times and the access time delay of the target calculation accelerator corresponding to the current task, and the scheduling memory device of the current task is determined according to the access cost. Therefore, the access cost of the scheduling memory device accessed by the target computing accelerator corresponding to each task is low, and the access execution efficiency of the target computing accelerator of the current task is improved.

This utility model belongs to the technical field of comparative test blocks and discloses a comparative test block for digital radiography (DR) pipe thickness measurement. It includes a magnetic block with a straight rod connected to its center. A stepped test block is installed in the middle of the straight rod, and a round bar is fixedly installed at the end of the straight rod. Based on the current availability of only one set of data to ensure the authority of the final data used, this method allows for the simultaneous acquisition of data from both the direct measurement method using a round bar and the experimental comparison method using a stepped test block in a single installation. The two sets of data are compared and verified, making the data more authoritative.

This invention relates to the field of electronic payment technology, and discloses a method and system for electronic evidence preservation for transaction security. The method includes: injecting a payment request as an evidence preservation identifier into the transaction data of a payment gateway to generate evidence-preserving transaction data; extracting key elements of the transaction and binding them with the user's payment identity credentials to form a structured evidence preservation instruction; performing a hash operation on the evidence-preserving payload of the instruction to obtain a digital digest; constructing a trusted evidence preservation data packet by combining a timestamp and the digital digest; generating an evidence preservation completion receipt by associating index information with the evidence preservation identifier as the main body; and digitally signing the receipt to finally obtain a digital evidence preservation certificate. This invention can enhance the evidentiary effect of electronic evidence preservation for transaction security.

This invention relates to the field of rolling mill technology, specifically to a rapid adjustment device for the parallelism of rolling mill rolls. The device includes a base plate, a vertical plate, and a main drive mechanism. The output end of the main drive mechanism is meshed with upper and lower distributed work rolls and support rolls. The support rolls penetrate the vertical plate and extend to both sides of the vertical plate. Bearings are fitted onto the work rolls and support rolls at positions corresponding to the vertical plate. The width of the bearing cross-section is greater than the thickness of the vertical plate. Guide grooves are formed on the vertical plate, and a hydraulic mechanism is fixedly installed at the upper end of the guide grooves. This invention allows for easy insertion of the acute-angled tip of a trapezoidal feeler gauge into the narrow gap between two cylindrical bearings, enabling precise positioning and stable support of the support rolls. Combined with a finely adjustable hydraulic lifting mechanism for the work rolls, it achieves standardized and quantitative measurement and comparison of the gap between the two ends of the rolls without relying on the operator's feel, thus providing a direct and reliable basis for rapid and precise adjustment of parallelism.
