Processing 1 ExaByte per Day for the SKA Radio Telescope


Published on

In this deck the Disruptive Technologies Panel at the HPC User Forum, Peter Braam from Cambridge University presents: Processing 1 EB per Day for the SKA Radio Telescope.

"The Square Kilometre Array is an international effort to investigate and develop technologies which will enable us to build an enormous radio astronomy telescope with a million square meters of collecting area."
