Before revision: We study the optimisation and porting of the "Modal" code on Intel(R) Xeon(R) processors and /or Intel(R) Xeon Phi(TM) coprocessors using methods which should be applicable to more general compute bound codes. "Modal" is used by the Planck satellite experiment for constraining general non-Gaussian models of the early universe via the bispectrum  of the cosmic microwave background  .
After revision: We study the optimisation and porting of the "Modal" , the simulation and analysis pipeline used by the Planck satellite experiment for constraining general non-Gaussian models of the early universe via the bispectrum of the cosmic microwave background .
