> HPC covers a lot of grounds, imho (cf beowulf mainling list, from

> - compute part: building the software (tuned for your cpu/gpu, ie
> openblas/atlas VS generic), SCL, Lmod/modules
> - easybuild/spark/nix/...
> - hardware (IB, dedicated hw such as FPGA, ...), ARM VS x86_64, ...
> - management (puppet/ansible/salt/...)
> - scaling on 10s on nodes VS 1000 VS more... (network/rack/datacenter
> management at scale)
> - user management (from plain /etc/{password|shadow} to FreeIPA, or Active
> Directory...)
> - shared storage, NFSv3/v4, pNFS, proprietary (cf panasas, gpfs,...)
> - and managing 100 TB or 100 PB is not the same (cf robinhood.sf.net)
> - distributed storage (client/server): tuned for different workload and
> requirements (quotas, ACLs, streaming VS IOPS, locking?, cheap?,
> expandability) lustre, beegfs, rozofs, moosefs, ..., ceph, glusterfs,
> - archiving/long term storage (irods?)
> - batch queuing: slurm and friends
> - containers (docker, singularity, ...)
> - web interfaces for non IT fluent users
> - remote visualisation (to avoid moving TB of data)
> - UEFI vs plain PXE/legacy booting
> - cloud expansion or cloud based for embarrassingly parallel workload ?
> - haddoop ?
> - what framework? warewulf as in openhpc, xcat, ks (foreman or DYI), ...
