    2828 * On each request, the scheduler decides whether to trust the host as follows:
    2929  * If E(H) > A, don't trust the host.
    30   * Otherwise, trust the host with probability 1 - E(H)/A.
     30  * Otherwise, trust the host with probability 1 - sqrt( E(H)/A ).
    3131 * If we decide to trust the host, preferentially send it unreplicated jobs.
    3232 * Otherwise, preferentially send it replicated jobs.  If we have to send it an unreplicated job, mark it as replicated and create new instances accordingly.
