摘要
Technologies for determining unique values include a computing device that further includes one or more accelerator devices. Each accelerator device is to receive input data and query configuration data, the input data including a packed array of unsigned integers of column data from a database and the query configuration data including an element width of the input data, and generate, in response to receiving the query configuration data, a bit-map output table based on the query configuration data, generate a write request for each element of the input data to set a corresponding bit-map output bit of the bit-map output table which corresponds to an element value of the corresponding element. Subsequently, the accelerator device is further to set the corresponding bit-map output bit to indicate a presence of the corresponding element and output the bit-map output table indicative of unique elements that are present in the input data.
