'''Data-Intensiveintensive Computingcomputing''' is a class of [[parallel computing]] applications which use a [[data parallel]] approach to processing large volumes of data typically [[terabytes]] or [[petabytes]] in size and typically referred to as [[Big Data]]. Computing applications which devote most of their execution time to computational requirements are deemed compute-intensive and typically require small volumes of data, whereas computing applications which require large volumes of data and devote most of their processing time to I/O and manipulation of data are deemed data-intensive.<ref>[http://www.cse.fau.edu/~borko/HandbookofCloudComputing.html Handbook of Cloud Computing], "Data-Intensive Technologies for Cloud Computing," by A.M.
