I noted “Japan’s Fugaku Keeps Position As Fastest Supercomputer.” There were two items of interest in the write up.
First, the machine:
performed over 442 quadrillion computations per second, around three times faster than the Summit system developed by the U.S. Oak Ridge National Laboratory.
Second, the chips in the Fugaku were Fujitsu’s. These may be the the Fujitsu A64FX microprocessor based on the ARM technology.
Intel and IBM are arm wrestling maybe?
