Despite the importance of nitrogen (N) limitation of forest carbon (C) sequestration at rising atmospheric CO2 concentration, the mechanisms responsible are not well understood. To elucidate the interactive effects of elevated CO2 (eCO2) and soil N availability on forest productivity and C allocation, we hypothesized that (1) trees maximize fitness by allocating N and C to maximize their net gr...

Over the past few years, as part of the Oak Ridge Leadership Class Facility project (OLCF-3), Oak Ridge National Laboratory (ORNL) has been engaged with several third party tools vendors with the aim of enhancing the tool offerings for ORNLs GPU-based platform, Titan. This effort has resulted in enhancements to CAPS’ HMPP compiler, Allinea’s DDT debugger, and the Vampir suite of performance ana...

Since 1964, as an adjunct to its automated technical information processing services to ERDA and other federal agencies, a generalized language translation system has been used by the Oak Ridge National Laboratory (ORNL) to translate Russian scientific text to English. The translation system, first implemented at Georgetown University around 1960, has been rewritten and improved through the yea...

Oak Ridge National Laboratory (ORNL) leads two of the five big Genomes-to-Life projects funded in the USA. As a part of these projects researchers at ORNL have been using PVM to build a computational biology grid that spans the USA. This talk will describe this effort, how it is built, and the unique features in PVM that led the researchers to choose PVM as their framework. The computations suc...
