Summary: The U.S. Department of Energy (DOE) plays a very special role in In fields where scientists deal with issues from disaster relief to the keeping you safe. DOE has two supercomputers in the top ten supercomputers in electric grid, simulations provide real-time situational awareness to the whole world. Titan is the name of the supercomputer at the Oak Ridge inform decisions. DOE supercomputers have helped the Federal National Laboratory (ORNL) in Oak Ridge, Tennessee. Sequoia is the name of Bureau of Investigation find criminals, and the Department of the supercomputer at Lawrence Livermore National Laboratory (LLNL) in Defense assess terrorist threats. Currently, ORNL is building a Livermore, California. How do supercomputers keep us safe and what makes computing infrastructure to help the Centers for Medicare and them in the Top Ten in the world? Medicaid Services combat fraud. An important focus lab-wide is managing the tsunamis of data generated by supercomputers and facilities like ORNL’s Spallation Neutron Source. In terms of national security, ORNL plays an important role in national and global security due to its expertise in advanced materials, nuclear science, supercomputing and other scientific specialties. Discovery and innovation in these areas are essential for protecting US citizens and advancing national and global security priorities.

GPGPUs are mainstream performance hardware in workstation and cluster environments and Available online 30 September 2020 their behavior in such setups are highly analyzed. Recently, NVIDIA, the leader hardware and software vendor in GPGPU computing, started to produce more energy efficient embedded GPGPU systems, Jetson Keywords: NVIDIA Jetson, series GPUs, to make GPGPU computing more applicable in domains where energy and space are limited. Embedded GPGPU, CUDA Although, the architecture of the GPUs in Jetson systems is the same as the traditional dedicated desktop graphic cards, the interaction between the GPU and the other components of the system such as main memory, central processing unit (CPU), and hard disk, is a lot different than traditional desktop solutions. To fully understand the capabilities of the Jetson series embedded solutions, in this paper we run several applications from many different domains and compare the performance characteristics of these applications on both embedded and dedicated desktop GPUs. After analyzing the collected data, we have identified certain application domains and program behaviors that Jetson series can deliver performance comparable to dedicated GPU performance.

    Titan is also a green powerhouse 14 November 2012 modestly more power than a CPU-only system. "With Titan, ORNL provides an exponential increase in scientific computing power toward predictive capabilities to address complex challenges without significantly increasing energy consumption," noted Jeff Nichols, ORNL associate laboratory director for computing and computational sciences. The Cray XK7 system contains 18,688 nodes, each with a 16-core AMD Opteron 6274 processor and an NVIDIA Tesla K20X graphics processing unit (GPU) accelerator. Titan also has more than 700 terabytes of memory. Not only is Oak Ridge National Laboratory's Titan the Because they handle hundreds of calculations world's fastest supercomputer, it is also ranked third in energy efficiency. simultaneously, GPUs can go through many more than CPUs in a given time.
