Abstract: Disclosed are techniques for processing user profiles using data structures that are specialized for processing by a GPU. More particularly, the disclosed techniques relate to systems and methods for evaluating characteristics of user profiles to determine whether to offload certain user profiles to the GPU for processing or to process the user profiles locally by one or more central processing units (CPUs). Processing user profiles may include comparing the interest tags included in the user profiles with logic trees, for example, logic trees representing marketing campaigns, to identify user profiles that match the campaigns.

Abstract: A pipe reaming tool for use with a bit driver includes a hollow cylindrical member having a plurality of cutting teeth disposed along the edge of one end of the cutting member and extending outwardly therefrom. A stop member is connected to the other end for limiting the depth of the ream to a predetermined length and a rod is connected to the stop member for engagement by a bit driver for rotating the tool.
