The collaboration between the groups in Theoretical Chemistry, Physical Chemistry and Structural Mechanics started in 1986. In 1996 the three groups enlarged with Theoretical Physics formed a center for scientific and technical computing at Lund University. Although the original groups still represent a large portion of the usage, today they are but a few among many different groups using the Lunarc systems.
Over the years LUNARC has gone through four stages - mainframe, workstations, multicpu SMP machines and PC clusters.
