Oak Ridge Summit Scheduled For 2018, Will Offer Up To 200 Petaflops Of Performance
Currently China holds the title for manufacturing the world’s fastest supercomputer, The Sunway TaihuLight, which offers 93 petaflops of performance. This machine has maintained the no. 1 spot in the top 500 list, and is three times more powerful then the second placed machine. However, things are about to change, as a US based, Oak Ridge Summit, supercomputer will give this machine a run for its money.
The Oak Ridge Summit will use a combination of IBM Power9 CPUs and Nvidia Volta GPUs. The Oak Ridge Summit is being developed by U.S Department of Energy, and will offer five times more performance compared to current Oak Ridge labs supercomputer named Titan.
This leadership class computing machine is scheduled to be powered on in early 2018 for the first time. Oak Ridge Summit will have a hybrid architecture, with each node will contain multiple IBM Power9 CPUs and Nvidia Volta GPUs.
All of these will be connected together with Nvidia’s high speed NVLink.
Each node will have over 512 GB of HBM and DDR4 memory, which will be accessible by every processor along with a buffer of 800 GB of NVRAM. Combine all of this and you will have a world most powerful supercomputer.
According to its creators the Oak Ridge Summit will open a new door to new ways to simulate and explore the complex systems in the natural world. Scientists using the Summit will be able to make their calculations faster and results will be more accurate and complex. Hopefully the power this supercomputer offers will provide solutions beyond the current experimental scope of the supercomputer.
Oak Ridge Summit was announced back in 2014, however, the specifications of this supercomputer have been completely revised. The expected performance of this supercomputer is 150-200 petaflops or more.
