Geosciences and the Office of Polar Programs HPCC activities build on a substantial infrastructure within the directorate. Incremental funds are used to enhance present activities and to synergistically integrate existing efforts into a geosciences program and the Global Change Research Program that is responsive and effective in using emerging technologies. The acquisition and testing (using Geoscience codes) of parallel computers of various architectures is being carried out to determine which technology offers the most promising capabilities. This initial work will guide the acquisition of a massively parallel machine in the FY 95-97 time frame.
Software that effectively uses parallel computers for geoscience problems is being developed and enhanced, including parallel algorithms to be used in models such as the Community Climate, global atmospheric chemistry, and eddy-resolving global ocean circulation models. Extended activities are carried out to provide access to unique scientific and informational resources by connecting the Antarctic science facilities to the Internet for high speed data transmission (especially during the southern hemisphere winter) of global data,images from telescopes, and general interactive tele-science from remotely located experimental centers. The education and training of geoscientists in high performance computing and communication is being addressed through a broad spectrum of courses ranging from program son a parallel computer to effective visualization techniques. These courses are offered at NCAR and the other NSF supercomputer centers. Graduate assistantships and postdoctoral positions that focus on HPCC activities are established at NCAR. Technologies are being developed for Internet distribution of real-time geophysical data that have multiple sources at separate locations. Geoscience data necessary for monitoring global change is widely distributed with total databases anticipated to grow to 10's of petabytes. The development of services, standards, tools, and user interfaces for storing, finding, transmitting,manipulating, displaying, comparing, and analyzing three dimensional historical and near real-time geophysical data is a major activity. It is the aim of this effort to allow a university user transparent access to petabytes of geosciences data located at several centers from which data of interest can be selected. |

Demonstrated Earth Simulation models simultaneously running on MPP, clustered and shared memory computers and connected by 'flux-coupler' software and high speed networking technology.
Upgraded Climate Simulation Laboratory 5 processor CRAY Y-MP/T3D machine to 8 processor CRAY Y-MP. Completed partial implementation of internet data distribution. Together with NASA and NOAA demonstrated the 256 Kbps data transmission between the U.S. and South Pole Station. |
Replace shared memory computer at NCAR and upgrade MPP machines.
Complete final development phase of Earth Simulation models running on different computers. Establish preliminary Volcano Network and fully implement geophysical data distribution. Establish an HPCC graduate and postdoctoral program for geosciences and revise exiting postdoctoral program to add HPCC thrust. Six to eight people will be supported. Enhance Mass Store software to effectively work with high performance MPP computers. Bring to operation 1.5Mbps link at Palmer Station, Antarctica using ACTS satellite. |
This activity is now incorporated into the activity described under Applications. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
