ARCHER (Advanced Research Computing High End Resource) is HECToR's successor, a petascale x86 supercomputer serving as the UK's primary academic research supercomputer. ARCHER begun operations in March 2014 becoming the most powerful system in UK and the 19th most powerful on the TOP500 at the time. ARCHER is expected to be succeeded by ARCHER 2 in 2020.
