New supercomputer in Wyoming to rank among world s fastest – New Delhi Times

January 28, 2021 Share A new supercomputer in Wyoming will rank among the world’s fastest and help study phenomena including climate change, severe weather, wildfires and solar flares. Houston-based Hewlett Packard Enterprise won a bid to provide the $35 million to $40 million machine for a supercomputing center in Cheyenne, the National Center for Atmospheric Research in Boulder, Colorado, announced Wednesday. The HPE-Cray EX supercomputer will theoretically be able to perform almost 20 quadrillion calculations per second 3.5 times faster than the existing machine at the NCAR-Wyoming Supercomputing Center. The new machine’s maximum speed per second will be roughly equivalent to each person on Earth completing a math equation every second for an entire month.
