Part 1 (overview)
Aim: support MPG scientist in data analysis, development etc.
MPCDF operate:
- several mid-range compute clusters,
- long-term storage tape archives,...
- remote-visualizaton infrastrcure (hardware, software)
- see webpage (docs.mpcdf.mpg.de)
Systems:
- HPC systems (Raven, Cobra, Draco), 5 year renewal cycle
- Manage Linux clusters owned by various institutes
- RVS (remote visualization): rvs.mpcdf.mpg.de, purely browser based, OpenGL rendering
- Jupyter notebook service
- HPC performance monitoring service (hpc-reports.mpcdf.mpg.de)
- Data service: https://gitlab.mpcdf.mpg.de (also wikis, issues, boards) Sign-in: selfservice.mpcdf.mpg.de ; allows gues accounts
- owncloud: datashare.mpcdf.mpg.de (sign-up: selfservice.mpcdf.mpg.de, allows guest accounts)
- Acount at mpcdf: www.mpcdf.mpg.de (For users - new users) Needs approval by director or representative
Accessing the clusters:
- Login through gateway machine (gatezero.mpcdf.mpg.de)
- Uses 2-factor authentication; needs OTP token
- Machines to connect: raven, cobra, draco e.g. ssh raven.mpcdf.mpg.de
Software on the cluster:
- wide range of compilers & libraries
- pre-built applications
- activate through environement modules
- containers: "last resort" solution if software cannot be compiled
- Charliecloud & Singularity are available
