===== Minerva =====


=== System description ===

Minerva is the current HPC cluster of the ACR group, delivered by [[http://www.clustervision.com|ClusterVision]] and commissioned in 2016.
It was bought for running Numerical Relativity simulations.\\
Minerva replaces Datura, which <del>will be switched off in early 2017</del> has finally been switched off and disconnected from power in mid-2018.

It consists of
  * 594 compute nodes (dual-socket, eight core Intel Haswell E5-2630v3 (2.40 GHz) // (=node[001-594]) //
  * two login and one management nodes // (=login[01-02],controller) //
    * (login nodes accessible as // minerva[01-02].aei.mpg.de //)
  * two storage systems running [[http://www.beegfs.com|BeeGFS]].
It provides in total
  * 9504 physical CPU cores
  * about 38,000 GB RAM (4 GB per core)
  * about 500 TB of disk space in 10 OSTs RAID-6 (10+2+1)
  * about 280 TFlop/s (measured with HPLinpack, P=22, Q=27, NB=192, N=2020224)
