History
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.
| 1986 - 1988 | IBM 3090 150/VF |
| 1988 - 1991 | IBM 3090 170S/VF |
| 1991 - 1997 | Workstations, IBM RS/6000 |
| 1994 - 1997 | IBM SP2, 8 processors. |
| 1998 | Origin 2000, 46 processors, R10000, 250 Mhz24 Gb processor memory, 64x9 Gb disk Onyx 2 |
| 1999 | Origin 2000, 100 processors, R12000, 300 Mhz |
| 2000 | Origin 2000, 116 processors, R12000, 300 Mhz |
| 2000 | Beowulf Cluster, linux cluster with 32 cpus and windows cluster with 8 cpus. The cpus were AMD 1.1 GHz. |
| 2001 | 64 of the Origin 2000 processors (embla) were sold to National Supercomputer Centre (NSC) in Linköping. |
| 2002 | A 65 processor Linux cluster called whenim64 was installed. The cpus are AMD Athlon 1900+. |
| 2003 | A cluster called toto7 with 128 Intel P4 2.53 GHz processors was added to the same queueing system as whenim64. |
| 2003 | 100 cpu cluster called sigrid was installed as part of the SweGrid project. |
| 2004 - 2005 | 210 cpu Opteron 148 (64-bit) cluster called docenten was installed. |
