Abstract: Abstract We give an overview of the two current UK national HPC services: HPCx and HECToR. HPCx was the flagship UK academic supercomputer from 2002 to 2007, at which point the larger HECToR system was installed. It is particularly interesting to compare the two machines as they will now be operating together for some time, so users have a choice as to which machine best suits their requirements. Results of extensive experiments are presented.
