Asst. Prof. Jeff Blanchard and his collaborator Prof. Jared Tanner (Oxford) recently launched www.gaga4cs.org as the platform for the first release of their compressed sensing software. The software, GAGA: GPU Accelerated Greedy Algorithms for Compressed Sensing, solves large compressed sensing problems with millions of unknowns in fractions of a second by exploiting the power of graphics processing units. Two related www.gaga4cs.org/research have also been submitted in the past year. This ongoing project is the major emphasis of Dr. Blanchard's NSF grant and has spawned three projects involving Grinnell Mathematics and Statistics majors.
