Two papers accepted to IEEE Access (Journal, SCIE)

Two papers were accepted to IEEE Access. One paper proposes GhostLeg, a low-overhead architectural defense approach against correlation-based GPU security attacks. GhostLeg selectively applies secure executions for load warps to minimize performance overhead induced by concealing memory coalescing. Another paper presents detailed characteristics of GCN aggregation kernels on GPU via an in-depth analysis using real GPU hardware and a cycle-accurate GPU simulator.
