Some apps scale upto several hundreds of thousands of cores. These are Gordon Bell award apps, with sustained levels around the PF. See this link : http://www.ncsa.illinois.edu/News/Stories/BW1year/apps.pdf Another one not in this list is DCA++, which has been ported also to GPUs. Jaguar had five applications that had sustained performance of over 1 petaflop on full applications: DCA++: 1.9 PF, LSMS: 1.8 PF, DRC: 1.3 PF, NWchem: 1.39 PF, and OMEN: 1.03 PF.
