The Cray XT system at ORNL is the world s most powerful computer with several applications exceeding one-petaflops performance. This paper describes the architecture of Jaguar with combined XT4 and XT5 nodes along with an external Lustre file system and external login nodes. We also present some early results from Jaguar.

The Interim Examination and Maintenance (IEM) Cell is located inside the Reactor Containment Building (RCB) at the Fast Flux Test Facility (FFTF). The IEM Cell is a shielded, hot-cell complex which houses the remotely operated equipment originally designed for the performance of nondestructive examination of core components and limited maintenance of reactor plant equipment. The cell is currently being used for preparation and packaging of fueled components into Core Component Containers (CCC) for transfer to dry storage. This analysis provides an assessment of radiological consequences onsite and at the site boundary for three bounding postulated accident scenarios.

In September 1996, the seal tube at the 3CL window of the Interim Examination and Maintenance (IEM) Cell at the Fast Flux Test Facility (FFTF) failed. Replacement of the seal tube required removing the 3CL master slave manipulator (MSM) and shielding creating a streaming path for radiation from irradiated fuel and activated hardware in the IEM Cell. As a part of the preparation for the seal tube replacement, expected dose rates in the IEM Cell gallery outside the open 3CL penetration during the repair work were evaluated.
The Fast Flux Test Facility (FFTF) interim examination and maintenance (IEM) cell is used for the remote disassembly of irradiated fuel and material experiments. The absorber open-test assembly (AOTA) is a 12-m (40-ft)-long instrumented absorber (control-rod-material) test assembly. Its primary purpose is to characterize the FFTF control-rod-material reaction rate during reactor operation. Instrumentation allowed temperature and pressure measurements at various locations in several absorber pins during reactor operation. After residing several months in the reactor, the assembly was transferred to the IEM cell by the closed-loop ex-vessel machine (CLEM) for separation of the irradiated portion of the experiment from the instrument stalk. After separation, the 3.6-m (12-ft)-long assembly was processed through the sodium removal system and shipped off-site for examination. This success allowed the timely completion of a major task on the FFTF operations schedule.

Nuclear Security Administration | (NNSA) Two of the World's Most Powerful Computers work for NNSA Monday, January 4, 2016 - 12:00pm NNSA Blog Two NNSA supercomputers-Trinity and Sequoia-are among the top six systems in the world, according to the 46th edition of the twice-yearly TOP500 list of the most powerful supercomputers released this month. Sequoia has been the world's third most powerful computer since June 2013, while Trinity is new to the top-ten list this fall in sixth place.

A principal tenant of the scientific method is that experiments must be repeatable and relies on ceteris paribus (i.e., all other things being equal). As a scientific community, involved in data sciences, we must investigate ways to establish an environment where experiments can be repeated. We can no longer allude to where the data comes from, we must add rigor to the data collection and management process from which our analysis is conducted. This paper describes a computing environment to support repeatable scientific big data experimentation of world-wide scientific literature, and recommends a system that is housed at the Oak Ridge National Laboratory in order to provide value to investigators from government agencies, academic institutions, and industry entities. The described computing environment also adheres to the recently instituted digital data management plan mandated by multiple US government agencies, which involves all stages of the digital data life cycle including capture, analysis, sharing, and preservation. It particularly focuses on the sharing and preservation of digital research data. The details of this computing environment are explained within the context of cloud services by the three layer classification of Software as a Service , Platform as a Service , and Infrastructure as a Service .
Each successive generation of computing system has provided greater computing power and energy efficiency.
