Total cranks up computing power to see more clearly below earth's surface

Oil company Total has almost tripled the performance of Pangea, a supercomputer it uses for analyzing subsurface imaging in search of new oilfields.
Pangea's performance is now 6.7 petaflops (floating-point operations per second), up from 2.3 petaflops, the French company said Tuesday.
That's enough to put it among the 10 fastest supercomputers in the world, according to Total, which based its claim on rankings published last November by Top500.org, the international supercomputer ranking organ
