Pacioli - Linux cluster of the UZWR


Our HPC-Cluster named Pacioli consits of one frontend, 39 compute nodes and a dedicated storage node.

  • The frontend and the nodes (001 to 016) feature two AMD Opteron 252 processors (2,6 GHz) and 8 GB of memory.
  • The nodes (017 to 035) feature two AMD Opteron 2218 dual-core processors (2,6 GHz) and as well 8 GB of memory.
  • The most modern four nodes (036 to 039) are based on Intels Sandy-Bridge-EP (Xeon E5-2630) processors, each equipped with 128 GiB of RAM.

Our cluster is named after the Italian mathematician and Franciscan friar Luca Pacioli who lived more than 500 years ago.  Among other things, he did major work on the double-entry bookkeeping system.

Upgrading 11/2010:
Another storage node ("storage01") with a capacity of 12 TB (10 TB for use, RAID5 ) was added to the cluster. Furthermore a newer operating system (Scientific Linux) and a cluster management system (Bright CM, Cluster Vision) was installed.

Updating 12/2012:
We replaced four of the oldest nodes of the cluster ("node002, 011, 012, 014") with modern nodes ("node036-039") characterized by 2x6 cores and 128 GiB each (see above).  We thank our member Prof. Rautenbach for funding the new hardware.
