High-temperature superconductors (HTS) are a vital technology for future particle accelerators, motors, generators and other electric power systems, fusion reactors, and many other medical and defense applications requiring high magnetic fields. One remaining limiting factor limiting to the implementation of HTS systems is the lack of adequate sensors to monitor the temperature and strain states o ...

Solid State Drives (SSDs) are emerging as attractive alternatives to traditional HDDs due to there reduced power consumption and potential for increased performance. SSDs have the potential to improve the performance of both Checkpoint Restart (CPR) and the Metadata Server (MDS) for high performance File Systems, e.g., Lustre. However, the write performance of SSDs is relatively poor (compared to ...

Energy consumption is quickly becoming one of the primary bottlenecks of compute clusters and supercomputers. The DOE is a primary developer and consumer of these power hungry supercomputers, however smaller cluster machines are also widely used through other government agencies and industries. Yet, there are few power profiling tools that allow application developers transparent insight into the ...

Due to huge levels of computing parallelism and higher performance per watt, comuting accelerators are crucial for increasing HPC efficiency. This is economically significant for small and medium size manufacturing companies (SMMs) and essential for transition to Exascale computing. However, due to high procurement costs, in-house maintenance of an accelerated HPC cluster is prohibitive for many ...

An important objective of the NEAMS program is to enable widespread use of the software tools among the industry, academia, and regulatory communities. For solving the problems occurring at various stages of NEAMS simulations, typically there are several possible choices for numerical subroutines. Furthermore, the best method for a numerical problem may also evolve over the course of the simulatio ...

In a catastrophic event, much of the electrical infrastructure can be damaged, even destroyed. The US Power Grid is a critical infrastructure and a catastrophic failure would result in huge humanitarian and economic loss. In addition, a widespread power outage would affect the readiness and response capabilities of various security agencies including Department of Homeland Security (DHS), Local P ...

The predictive modeling approaches and softwares being continually developed and updated by the DOE nuclear engineering scientists (under programs such as NEAMS, CASL, RISMC etc.) need to be efficiently transferred to the nuclear science and engineering community. An advanced workflow management workbench is required to allow efficient usage from small and large bossi- ness and research groups. Th ...

The feasibility for fusion as a practical energy source needs to be enhanced significantly by removing some of the restrictions that low-temperature superconductors put on the fusion magnet systems. This can be done by using high-temperature superconductors, allowing for much larger temperature margins, a higher magnet performance and less mechanical degradation during operation. There are curren ...

Currently the commercially available technologies for H2 separation such as pressure swing adsorption and cryogenic distillation are very energy intensive. Membrane technologies can be very energy efficient; but for high selective membranes low flux and high cost are the major challenges that frustrate commercialization. Recently, cermet has shown promise because of less precious metal usage and m ...

Higher operating temperature for the gas turbine engine is needed for enhanced efficiency, lower emission and increased performance goal. The current state-of-the-art thermal barrier coatings (TBCs) are not adequate to provide the needed protection for the metallic components of the turbine engine operating at higher TBC surface temperature (>1300
