Here’s a riddle: when new GPUs are constantly being produced, product cycles are ~18-24 months long, and each cycle doubles GPU power (per Huang’s Law), what happens to 10-year-old server GPUs? Here at Trail of Bits, we want to use old GPUs—even those past their official end of life—to solve interesting computer security and program analysis problems. This is not a use of GPUs, but is related to GPU programming: We believe that we can use MLIR and Trail of Bits’ VAST to transparently compile code across API layers.
