equilvalence of ARM versus x86 for numerical computation?

    As ARM is making inroads into the cluster market, I am curious
    how easy it will be to switch to this platform.

    In the noughties I worked for a company using clusters of Opterons.
    They looked at using Teslas for parallel grunting. However these had
    different rounding errors. Since many of their algorithms involved
    successive approximations, it took six programmer-months to tweak code
    and prove they got the same results as on x86.
