    1. Fast Computation of Database Operations using Graphics Processors Naga K. Govindaraju Univ. of North Carolina

    2. Goal Utilize graphics processors for fast computation of common database operations

    3. Motivation: Fast operations Increasing database sizes Faster processor speeds but low improvement in query execution time Memory stalls Branch mispredictions Resource stalls Eg. Instruction dependency One of the main reasons for requiring fast database operations is the increase in database sizes leading to an increase in query execution time. On the other hand, improvements in semi-conductor technology lead to faster processor speeds. However, there is relatively low Improvement in query execution time as traditional database operation implementations involve memory stalls due to cache misses, branch mispredictions due to conditionals, resource stalls due to instruction dependencies etc. Therefore, there is a need to develop new algorithms that take advantage of the architecture features and reduce query execution timesOne of the main reasons for requiring fast database operations is the increase in database sizes leading to an increase in query execution time.
