While CUDA has been the dominated parallel computing platform and programming model for general-purpose GPU computing, CUDA synchronization undergoes significant challenges for GPU programmers due to its intricate parallel computing mechanism and coding practices. In this paper,we propose AuCS, the first general framework to automate synchronization for CUDA kernel functions. AuCS transforms the original LLVM-level CUDA program control flow graph in a semantic-preserving manner for exploring the possible barrier function locations. Accordingly, AuCS develops mechanisms to correctly place barrier functions for automating synchronization in multiple erroneous (challenging-to-be-detected) synchronization scenarios, including data race, barrier divergence, redundant barrier functions. To evaluate the effectiveness and efficiency of AuCS, we conduct an intensive set of experiments and the results suggest that AuCS can automate 20 out of 24 erroneous synchronization scenarios.
