TOP500 supercomputer: Once again, if you are looking for the fastest and most powerful computer, the TOP500 supercomputing ranking for June 2018 shows that Linux dominates the operating systems. To put it another way, every computer in the TOP500 supercomputing runs on Linux.
Linux has dominated for many years, but since November 2017 it was the first time that all machineof the TOP500 use Linux. Before 2017 there were also a few IBM AIX, a Unix variant, very low on the list.
For the future there is no doubt that Linux will continue to dominate supercomputing as there seems to be no competition.
Linux companies like Red Hat will help Linux stay on top. Red Hat is powering the new number one Summit supercomputer (the American company energyof Oak Ridge National Laboratories, to "lead" the list. The computer is running Red Hat Enterprise Linux (RHEL).

In the latest TOP500 rankings, 56% of the additional flops were a result of its GPUs NVIDIA Tesla. This marks the first time that the GPU has surpassed the CPU in super performance computers.
For example, the new Summit champ is powered by boards that work with two IBM Power9 CPUs and six V100 GPUs. According to NVIDIA, 95% of the peak performance (187,7 petaflops) comes from the system's 27.686 GPUs.
NVIDIA also dominated with the less powerful Sierra GPU, used by the world's third fastest supercomputer with 71,6 Linpack petaflops. It has four GPU V100s in each node Power9 dual connection, instead of six (IBM Power System S922LC, IBM POWER9 22C 3.1GHz, NVIDIA Volta GV100, Dual-rail Mellanox EDR Infiniband, IBM
DOE / NNSA / LLNL).
