The High cadence Transient Survey (HiTS) is a survey looking for fast optical transients in the southern sky using the Dark Energy Camera (DECam). HiTS pioneered the real-time analysis of DECam data, managing to analyze a data stream of more than 33 Mbps coming from CTIO via optical fiber link (REUNA), using the supercomputer leftraru at the National Laboratory for High Performance Computing (NLHPC), hosted at CMM, with a custom built pipeline which uses advanced techniques from image analysis, high perfomance computing, machine learning and visualization.

With the operation of the ALMA radio-interferometric observatory, a large amount of preprocessing will be required. The ALMA instrument observatory has already begun operations with reduced capabilities, and will reach completion by 2013, recording several GB per day in Fourier space radio signals over 60 antennas, in a 16 km wide surface.
