The SCIAMA supercomputer based at the University of Portsmouth is approaching its fifth birthday. Up to now, around two hundred and fifty researchers have used the environment, including ICG members, the wider University of Portsmouth, and SEPnet. Many of the researchers collaborate with the ICG from institutions around the globe, logging in and using the facilities remotely.

The many users have enjoyed an uptime of better than 99%, any short outages mainly having been for upgrades. From an initial 960 cores there have been two further upgrades bringing the compute core count to over 3,700, and with the storage now approaching 1 petabyte. Over 30 million hours (nearly 3,500 years) of processor time have been recorded so far, with that number continuing to grow rapidly following the latest upgrades.
