Abstract
This application describes methods, systems, and apparatus, for neural network-based program sampling (NPS). An example device may obtain an assembly code of a program and an execution trace of the program, and divide the assembly code into a plurality of execution intervals. The device may construct a plurality of code graphs respectively corresponding to the plurality of execution intervals, and for each of the plurality of code graphs: generate a plurality of graph snapshots based on the code graph and the execution trace of the program; embed, by using a Graph Neural Network, the plurality of graph snapshots into a plurality of vectors; and aggregate the plurality of vectors into an execution embedding. The device may cluster the plurality of execution embeddings into a plurality of clusters and select representative execution intervals of the program based on the plurality of clusters for execution.
