Algorithm for the Placement of Adapters in a Personal Computer System

       This article describes an algorithm by which a user can
place adapters within a personal computer (PC) system to gain
advantage of the availability of the cooling characteristics of the
system.

      Typically, there is no automated means by which adapters can be
placed in a PC system expansion area to maximize the benefits of the
convection.  Certain slots are inherently cooler than others by
virtue of their proximity to the fan and other cooling
characteristics of each particular system.  This means that the
coolest slots will be different in each system.  The algorithm
disclosed herein helps the user select the slots for each adapter.

      A power and thermal configurator for the system is required to
provide information essential to the algorithm as follows:
      - An ordered list of slots - Coolest slot first, hottest slot
last
      - An ordered list of adapters - Hottest adapter first, coolest
last
The algorithm assumes access to these lists in the most expeditious
manner.  It works with these lists to generate another list.  This
resulting list is the placement list for the ordered list of cards.

      The algorithm takes into consideration the fact that it is most
desirable to place the hottest card in the coolest card slot.
Typically, this will mean taking the card number off the ordered
adapter list (shown in Fig. 1) and associating it with a slot tak...
