The AMD-based El Capitan supercomputer isn't set to go online until 2023. However, in preparation for the new exascale supercomputer, the National Nuclear Security Administration (NNSA, not to be confused with the NSA or NASA) has produced three smaller prototype supercomputers to test out El Captains' hardware systems. Despite not being the real supercomputer deal, these three computing monsters have been found to pack a serious punch, with each landing on the top 200 list of the world's fastest supercomputers.
El Capitan is a brand-new exascale supercomputer behemoth being built for the NNSA that will be responsible for modeling nuclear weapon simulations. Once completed, El Capitan is expected to be, at the very least, the fastest supercomputer owned by the United States government, with an estimated 2 exaflops of computing power.
Out of the three systems, rzVernal ranks the fastest with and lands at number 123, featuring 4.1 petaflops of performance in High-Performance Linpack. Tioga landed close behind at number 135, with 3.67 petaflops, and Tenaya edges onto the list at number 200, with 2.86 petaflops of performance. But, again, that is position 200 on the list of the fastest supercomputers worldwide, so it's far from a bad result.
