Linux at RUM
- 1995: Web stations all around the university
- 1996: Trumpf Beowulf Cluster
10 P133 SMP, Ethernet. Applications: PVM, MPI and a distributed indexer and search engine. First experiences with Apache on Linux - 1996: Various databases: TOP500 Database, History database, RUM Library
- 1997: Siemens Primergy Quad PPro200. As node 11 in the trumpf cluster
- 1997: Comyc Cluster
8 PPro 200 SMP, Myrinet, diskless nodes - 1997: As a Desktop with KDE and WindowMaker
- 1998: WWW Server for www.top500.org

- 1999: Samba PDC (Primary Domain Controller) for HPC/WWW Group. File Server, Print Server..
- 1999: top500.org powered by Siemens Primergy
- More projects planned
- Applications and development tools are widely and freely available
- Powerful servers with APIs to almost anything
- Our experience:
Linux + Apache + Mysql + PHP3 =
Powerful and free Intranet/Internet platform
- We are neither Yahoo nor Lycos....
- but to have 257.245 hits in one day is really encourging....
- Samba
- Linux can replace windows NT to control domains (PDC).
- Used to provide file and print services.
- Web Administration Tool (Swat) available
- Easier local and remote administration.
- Better performance:
- SMP
- 2.0.0 had poor SMP support (First stable kernel series with SMP support)
- SMP needs applications which use SMP capabilities
- Quad SMP on Primergy seems to work with a noticable stabiltity
- High availabilty (Uptimes of 100 days and more)
- HPC programing environment freely available
- Interconnect hardware support available
- Diskless configurations stable and ease administration
- Highly scalable: add or remove nodes whenever necessary
SAP R/3 in Mannheim
- 1998-: SAP R/3 (IDES) on RM1000
