Abstract: A method, a computer or computer program product for automatically restructuring a program having arrays in inner loops to reduce an average penalty incurred for bursty cache miss patterns by spreading out the cache misses. The method may be used separately or in conjunction with methods for reducing the number of cache misses. The method determines a padding required for each array according to a proportion of the cache line size, to offset the starting points of the arrays relative to the start of a cache line memory access address for each array. Preferably, the starting points of the arrays that induce bursty cache misses are padded so that they are uniformly spaced from one another.

Abstract: An ambient air condition sensor housing includes a front portion releasably coupled to a rear portion and defining an interior space therebetween adapted to retain at least one ambient air condition sensor. The rear portion defines apertures for passage of the ambient air therethrough. A labyrinth having a plurality of spaced apart upstanding walls is integrally attached to an inner surface of the rear portion and is positioned so as to cooperate with the air condition sensor. Each wall of the labyrinth includes a slightly arcuate configuration for funneling the ambient air toward the air condition sensor. The rear portion and labyrinth are completely covered with a black coating so as to minimize light reflectivity within the interior space whereby to enhance proper functioning of the air sensor.
