Uncle Sam's next big supercomputer might use something more exotic than GPUs

Of the world’s most powerful supercomputers, nine of the top 10 are powered by GPUs, but that might not be the case for much longer. As chipmakers like Nvidia prioritize AI FLOPS over the ultra-precise floating point calculations used in scientific computing, US National Labs are turning to new chip architectures to get their FP64 fix. Among the candidates is NextSilicon’s Maverick-2, a dataflow processor designed explicitly with the 64-bit floating point mathematics that dominate the Department
