The gravity field dedicated satellite missions like CHAMP, GRACE, and GOCE are supposed to map the Earth’s global gravity field with unprecedented accuracy and resolution. New models of Earth’s static and time-variable gravity field will be available every month as one of the science products from GRACE. Here we present an alternative method to estimate the gravity field efficiently using the i...

A vector instruction set is a well known method for exposing bandwidth to applications. Although extensively studied in the scientific programming community, less work exists on vectorizing other kinds of applications. This work examines vectorizing a traditional database operation, a Grace hash-join. We how to vectorize both the hash and join phases of the algorithm, and present performance re...
