cray supercomputers?

Question

what is the application of the cray xt3??anybody can help me..

Answer 1

Don't know the xt3 exactly, but a generic answer to the use of supercomputers is the application of finite element programs. Suppose you want to know what will happen if the space aliens stole Hoover Dam is a flash. Just divide all the water behind it into 1 cubic foot pieces, number them all, and solve the simple equation of F=ma. Assume that each cube will always be a cube. Remember the force applied to the front row to hold it in place. Now, remove that force and solve for the forces at that instant. With the new forces, find the value for "a" for each piece of water, assume that a millisecond has passed, and calculate where each piece is then. That will change all the forces. With the new forces, calculate new values for all the "a"s. Allow another millisecond and move them all again. On your CRT, observe the resulting flood. Afterwords, flex a jet airliner's wing and model the weather over the planet. Same thing. Divide the thing into small pieces and handle each with simple mathematics. But, that takes a lot of computer horsepower and that is where Cray comes in. Want to see a really big one? Look up the Lawrence Livermore National Laboratory and rummage around their site. They are very proud of their supercomputer, an IBM product.
