Hi to all,

We had a TELCO on 20170426. Here are brief NoM.

- We will provide the credentials for members of SIG to have access to real
HPC system.
- We hope to meet in a person very, so we can show infra and discuss needs
and workflows in HPC domain.
- SIG members have been provided with project ID at IT4Innovations and an
email describing how to apply for the credentials.
- We hope to have another TELCO, date not set yet.

Regards,
DH

>> - 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), ...
>>
