Abstract: Disclosed are a subgraph matching strategy determining method, a subgraph matching method, a counting method, and a device; the matching strategy determining method includes: obtaining a pattern; generating a plurality of restriction sets, for the pattern, each restriction set being capable of eliminating all other automorphisms different from the pattern per se in the automorphisms of the pattern; obtaining a plurality of search order schedules, for the pattern; combining the plurality of restriction sets and the plurality of search order schedules, each combination being referred to as a configuration; using a performance prediction model to predict a computation amount of a subgraph matching algorithm corresponding to each configuration, and determining one or more configurations as a subgraph matching strategy, based on the predicted computation amount.

Abstract: A computer executed parallel program scalability bottleneck detection method is provided, which includes: building a program structure graph for a program source code; collecting performance data based on a sampling technique during runtime; the performance data including: performance data of each vertex of the program structure graph and inter-process communication dependence of communication vertices; building a program performance graph by filling the program structure graph with the collected performance data, the program performance graph recording data and control dependence of each process as well as inter-process communication dependence; detecting problematic vertices from the program performance graph, and starting from some or all of the problematic vertices, backtracking through data/control dependence edges within a process and communication dependence edges between different processes, to detect scalability bottleneck vertices.

Abstract: Disclosed is an artificial intelligence infrared thermal imaging bra system with breast disease detecting function. The system includes a side support, two chest support layers and two shoulder straps; the two shoulder straps are fixed at both ends of the side support, and the two chest support layers are symmetrically fixed between the two shoulder straps at the top of the side support; the two chest support layers are internally provided with sliding mechanisms that are adjustable according to different chests of users; a rotating mechanism for driving the sliding mechanisms to move is arranged between the two chest support layers at the top of the side support, and the rotating mechanism and the sliding mechanisms are in transmission connection; one end of the side support is fixed with a sub-buckle, and the other end of the side support is provided with a stretching mechanism.
