Petascale large eddy simulation of jet engine noise based on the truncated SPIKE algorithm
We apply the truncated SPIKE algorithm to petascale simulation of jet engine noise. We derive a tridiagonal linear system solver from the truncated SPIKE algorithm. The new solver has optimal weak scalability not found in traditional methods. Experimental data show the new solver to be much faster than traditional methods.
