Interesting Grid Applications

Environment/Earth

Earth Science Grid 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.securitysystem monitoring UCAR

Medicine/Biology

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
