Software Roadmap to Plug and Play Petaflop/s

Description: In the next five years, the DOE expects to build systemsthat approach a petaflop in scale. In the near term (two years), DOE willhave several near-petaflops systems that are 10 percent to 25 percent ofa peraflop-scale system. A common feature of these precursors to petaflopsystems (such as the Cray XT3 or the IBM BlueGene/L) is that they rely onan unprecedented degree of concurrency, which puts stress on every aspectof HPC system design. Such complex systems will likely break current bestpracti… more

Harnessing the Department of Energy’s High-Performance Computing Expertise to Strengthen the U.S. Chemical Enterprise

Description: High-performance computing (HPC) is one area where the DOE has developed extensive expertise and capability. However, this expertise currently is not properly shared with or used by the private sector to speed product development, enable industry to move rapidly into new areas, and improve product quality. Such use would lead to substantial competitive advantages in global markets and yield important economic returns for the United States. To stimulate the dissemination of DOE's HPC expertise, … more

A framework for graph-based synthesis, analysis, and visualization of HPC cluster job data.

Description: The monitoring and system analysis of high performance computing (HPC) clusters is of increasing importance to the HPC community. Analysis of HPC job data can be used to characterize system usage and diagnose and examine failure modes and their effects. This analysis is not straightforward, however, due to the complex relationships that exist between jobs. These relationships are based on a number of factors, including shared compute nodes between jobs, proximity of jobs in time, etc. Graph-bas… more
