benjamin_redlingWorking part-time in IT since 1999, I joined Prof. Hahn's group in November 2006 as a system administrator.

Over the years I maintained a FC-SAN, had to cope with Solaris with SAM-FS, planned and administred two compute clusters which I heavily upgraded all by myself, introduced the SLURM batch scheduler and a ganeti cluster for virtualization.

Just recently I started to climb the rough edges of CUDA installations for Deep Learning and after a month of painful "doing-it-the-hard-way" happily recommend using the Anaconda Python distribution.

Recent Working Experience

  • Installation and mainteanance of the groups SLURM cluster (15 nodes+)
  • Installation and trouble-shooting of the groups MATLAB Distributed Computing Server (6 nodes, up to 95 cores/workers)
  • Setup and tuning of PostgreSQL installations (2TB+)
  • Basic Linux infrastructure (NFS4 file server, OpenLDAP, FAI)
  • Monitoring and annalising with Check_MK / OMD
  • Setup of ElasticSearch clusters
  • Planning, coaching a complex installation and on-going maintenance of the groups Ganeti (KVM/DRBD) cluster (currently 6 nodes)
  • Supervision of student assistants
  • Supporting junior Java developers
  • Configuration management and orchestration via ansible and basic shell scripting
