  • Exa- is a prefix denoting 1018, or 1,000,000,000,000,000,000.
    • In computing, a Thread refers to the smallest sequence of programmed instructions an operating system can perform, typically one thread per CPU, though this can be multiplied via Multithreading. A "billion giga-threads" is exactly one exa-thread (109 × 109 = 109+9 = 1018); for comparison most commercially available CPUs can perform anywhere from 1 to 32 threads.
