The US Department of Energy (DOE)s networking cyber infrastructures are experiencing a massive explo- sion of data volumes because of emerging e-science applications to support high-energy physics, astrophysics, genomics, climate modeling, large-scale science collaborations, etc. The same is true for other networks around the world to support smart devices, big data applications, social ne ...

Designing an efficient and scalable network fault diagnose tool for such a complex system is facing the following challenges: 1) Inherently unpredictable and fault-prone status in the involved networks for scientific collaboration and science mission due to the dynamic nature of network and service demands, and the increasing complexity of configuration options resulting from the imp ...

As supercomputing speeds increase and storage costs drop, scientists running applications in various disci- plines, such as high-energy physics, genomics, climate studies, etc., generate datasets of ever-increasing sizes at distributed locations around the world. Backbone Research-and-Education Network (REN) providers such as DOEs Energy Sciences Network (ESnet) and Internet2, provide high-speed, ...

This Small Business Innovation Research proposal presents AutoPHY, an autonomous, virtualized layer 0 interconnection service for data centers and cloud computing. The Open Systems Interconnection (OSI) stack representing the Internet infrastructure consists of layers 0 to 7. Today all layers can be automatically configured and managed through software, with the exception ...

The interconnect networks of datacenters and extreme scale high performance computers (HPC) will require a bandwidth density, in terms of connections per area, that cannot practically be met with todays optical transceiver technology. The push for high-radix connectivity in combination with an ever increasing amount of data transported on these advanced networks requires increasing num ...

This DOE SBIR program would develop a manufacturing process to produce plastic optical fibers with bandwidth, bend loss and ease of installation significantly improved over currently available products. Current polymer optical fibers are manufactured using bulk polymer processing methods. These methods limit the types of fiber waveguides that may be formed, so significantly l ...

High-resolution and accurate terrestrial moisture, temperature and carbon conditions are increasingly demanded for precision energy, agriculture, water, and disaster management. However, the required information must be integrated and inferred from huge volumes of satellite, in-situ, and morel information that is produced by many different agencies and organizations. To address these issues, the ...

Additive manufacturing technology creates objects using a sequential layering process that directly contrasts with the traditional subtractive approaches commonly used to manufacture the majority of fabricated components. The additive manufacturing technology can be used anywhere throughout the product life cycle, from pre-production to full-scale production in addition to tooling applications and ...

Software development faces many challenges as high-performance computing (HPC) moves towards exascale: scalability, programmability, performance portability, resilience, and energy efficiency. To tackle these challenges, fundamental shifts in the basic execution models and programming models employed by HPC software are required. In particular, commonly used linear algebra libraries performance s ...

The availability and continued growth of High Performance Computing (HPC) is opening new avenues for complex physics based software simulations. The usage of HPC is particularly important in high-fidelity Large-Eddy Simulation (LES) a branch of computational fluid dynamics (CFD) of multi-physics engineering problems such as the development of more efficient and less polluting advanced energy ...
