TOP500 supercomputer the list of top for June of 2018

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 been around for many years, but since November 2017 it was the first time that all TOP500 machines have used Linux. Before 2017 there were 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 powers the new number one supercomputer Summit (from the American energy company Oak Ridge National Laboratories, to "lead" the list. The computer runs on Red Hat Enterprise Linux (RHEL).

• Summit - IBM Power System AC922, IBM POWER9 22C 3.07GHz, NVIDIA Volta GV100, Dual-rail Mellanox EDR Infiniband , IBM
  DOE / SC / Oak Ridge National Laboratory

In the latest TOP500 rankings, 56% of the extra flops were due to NVIDIA Tesla GPUs. This marks the first time that the GPU has surpassed the CPU in supercomputer performance.
For example, the new Summit champ is powered by boards running on two IBM Power9 CPUs and six V100 GPUs. According to NVIDIA, 95% of the top 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).
