That era ended. Peak floating-point throughput stopped scaling the way it used to, and the compute density now available in leadership-class machines comes almost entirely from GPU accelerators — thousands of streaming multiprocessors per node, operating under a fundamentally different programming model than the CPU clusters that most production scientific software was written for.</p>
