perfSONAR is a framework for developing multi-domain measurement and monitoring services. This framework separates the collection of data from the use of this data. It also provides access control mechanisms and services that allow network providers to control how collected data is shared with peers and other potential data consumers. The ability to separate data collection from data consumption p ...

network infrastructure must be actively managed to ensure that the infrastructure itself does not become a major performance bottleneck. This management requires an understanding of how traffic is currently flowing, making predictions about how traffic flows will change in the future, and, increasingly, how much energy this infrastructure is using. Network operations staff need tools and services ...

Optical networks have revolutionized wide area network infrastructure deployments providing ever increasing amounts of bandwidth at ever decreasing costs. As costs dropped, optical network components moved out of the wide area and into the metro area and now the home distribution environment. This expansion requires a shift away from small numbers of very expensive optical test gear to a world wit ...

Over the past 30 years, The Department of Energy’s (DOE) supercomputing program has played an increasingly important role in scientific research by allowing scientists to create more accurate models of complex processes, simulate problems once thought to be impossible, and analyze the increasing amount of data generated by experiments. Computational Science has become the third pillar of science ...

HPC modeling and simulation applications are utilized by many industries in their product development cycle, but hurdles remain for wider adoption especially for small and medium sized manufacturing and engineering firms. Some of the hurdles are: overly complex applications, lack of hardware resources, inability to run proof of concept simulations on desktop workstations, solutions that have well ...

Many tools and services have been developed over the years to support the HPC user and development community. These tools (debuggers, profilers,workflow engines, low-level libraries, etc), although very powerful, take a good deal of time and effort to learn and use. For a company to utilize HPC in the development of their product or service they need to invest a substantial amount in learning thes ...

The Office of Science (SC) Office of Advanced Scientific Computing (ASCR) has invested millions of dollars in the development of HPC software in the areas of modeling and simulation, solvers, and tools. Many of these tools are open source, but are complex “expert” level tools. The expertise required to install, utilize and run these assets poses a significant barrier to many organizations due ...

World-wide energy production is modifying the chemical composition of the atmosphere. Such modifications are linked not only with environmental degradation and human health problems but also with changes in the most sensitive parts of the physical climate system – namely, clouds and aerosols. The Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) examined the effect ...
