Interesting Grid Applications

Environment/Earth

Earth Science Gridhttps://www.earthsystemgrid.org/

• Producing, archiving, and providing access to climate data that informs research on global climate change. This image displays data from ESG and shows sea ice extent (white/gray), sea ice motion, sea surface temperatures (colors), and atmospheric sea level pressure (contours). ESG uses Globus software for security, data movement, and system monitoring. Image provided by UCAR.

DNA as a linear array

Sequence alignment problem• Sequences used to find biologically meaning relationships among organisms

–Evolutionary information–Determining diseases, causes, cures–Finding out information about proteins

• Problem especially compute intensive for long sequences–Needleman and Wunsch (1970) - optimal global alignment–Smith and Waterman (1981) - optimal local alignment–Taylor (1987) - multiple sequence alignment by pairwise

alignment–BLAST trades off optimal results for faster computation

• Challenge - achieve optimal results without sacrificing speed

Physics

Modeling Black Holes• Einstein’s equations of General Relativity: Gab = 0

• One of the most complex set of equations in physics– Mixed hyperbolic-elliptic initial value problem– 3 Dimensional, multiple scales– 12 or more equations, with thousands of terms

• Require diverse distributed collaborations & many large scale simulations:– Parallelization, optimization– Parallel IO, data management, viz– Checkpointing, steering, interaction

Class project

• Each person to find one interesting grid computing application or topic and present 1 slide to WebCT (assignment 6)

• Search Internet for material. Provide URL on slide

• 2% of overall grade if submit slide for class Thursday Nov 17th, 2005 (by 11 am) and are there to say a couple of words about your slide.
