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.
After revision: We present a case study describing efforts to optimise and modernise "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.
