SAMD is a demonstrator project funded by the ESRC to demonstrate the benefits of applying Grid technologies to a social science research question. SAMD is short for Seamless Access to Multiple Datasets. The aim of SAMD was to simplify the process both of accessing data and the computer resources for analysing this data. In practice, this meant that a task that would normally take the best part of a day was actually completed within an hour.
The SAMD team built a mini demonstrator Grid that involved creating a specific Grid 'architecture' to incorporate a major social science databank drawn from the National Statistics (NS) Time Series Data hosted by MIMAS. (See Unit 2 for more details). This demonstrator Grid involved:
The single sign-on feature of SAMD provides the seamless access to datasets mentioned above. This feature enables multiple access to various compute resources including datasets and High Performance Computer (HPC) machines that make themselves available to the Grid community.
