Titan is a parallel scientific database for remote-sensing data . In addition to retrieving data, Titan performs navigation, correction and composition to generate a land-cover image of the region of interest. The region of interest is specified by temporal and geographical (latitude-longitude) ranges. This application performs I/O using the asynchronous lio_listio() operations. It throttles the number of requests to keep the number of outstanding I/O requests under a user-specified limit.
Titan contains two months of data from the NOAA-7 satellite. The total database size is 30 GB which spans 60 data-files.
To drive this application, we used three queries which span a 30-day period over the entire globe, North America and Asia respectively .
You can download the trace files in the following formats:
