IΜΒBC HPC (“zorbas”) usage policy

Χ: no need for booking (ie. the task can be submitted without resource reservation request) √: need for booking (the task needs approval prior to proceeding) n/a: not applicable To request a new account or software components and to submit a booking request visit: https://hpc.hcmr.gr/helpdesk, to view existing bookings: https://hpc.hcmr.gr/booking, for more info: https://hpc.hcmr.gr
T6. Jobs employing new software components (i.e. that have not been used before on the cluster) should be declared as such. Prior to analysis an initial test run in collaboration with systems administrators is mandatory. Test runs can take place only during office hours on weekdays (except Friday)
T7. The resources of demonstration jobs (e.g jobs in context of a conference, a meeting or a graduate/postgraduate lesson) have to be always specified (so as their execution can be properly scheduled)
T8. Minimum period of responding to a request (e.g. new software installation, new user, general troubleshooting) is two weeks. The IMBBC HPC team tries to serve every request as quickly as possible. A response in less than two weeks cannot and should not be taken for granted. Please plan ahead. Projects and visiting IMBBC HPC researchers should be declared at least two weeks in advance.

	IMBBC HPC User profiles
	Basic	Advanced	Exceptional
Policy	Available storage: 200GB	Available storage: 600GB	Upon request extra storage or other resources can be allocated for a predefined period of time. This allocation is project (analysis) specific. For multiple projects, multiple requests are required.
Gain Access	To become Basic or Advanced a request form must be submitted	To become Advanced user, an extra request must be submitted by the corresponding supervisor.	Please contact the system administrators

Resource
allocation requests will be reviewed** according to:

1. Adequate
   description of the methodology

2. Compliance
   with resource limits per user profile

3. Efficient
   past use of resources. The committee reserves the right:

   1. of
      proper re-allocation of tasks to appropriate server/queue (when
      applicable) based on past software history

   2. to
      request a community best-practice methodology when applicable

4. The
   current load of the infrastructure and of the support team

5. Job
   execution risk, see term T6 above

T9.
For requests that involve the HPC system (defined as “tasks managed
by the SLURM scheduling system and running in the Zorba cluster”)
full support is
provided. Beyond Zorba, full support will be provided for non-Zorba
requests with a broad audience. The
IMBBC HPC team reserves the right to provide basic
support to any other projects

T10.
The IMBBC HPC team cannot support tasks that exceed its capacities.
It is there however to assist seeking alternatives for any interested
parties

T11.
The above policy is subject to annual evaluation and update based on:
cluster usage statistics, user feedback, and invited external review

T12.
By using the IMBBC HPC you agree that non-personal and anonymous
usage statistics data are collected to support the previously
mentioned analytical actions

T13.
Idle accounts will be deactivated after six months and archived after
a year of inactivity. Archived data will be removed two years after
unless otherwise requested.

T14.
The IMBBC HPC accounts are personal and may not be transferred to
other users. Sharing passwords is not allowed.

T15.
Upon
publication, the IMBBC HPC, will be acknowledged as:

This
research was supported in part through computational resources
provided by IMBBC (Institute of Marine Biology, Biotechnology, and
Aquaculture of the HCMR (Hellenic Centre for Marine Research).
Funding for establishing the IMBBC HPC has been received by the
MARBIGEN (EU Regpot) project, LifeWatchGreece RI, and the CMBR
(Centre for the study and sustainable exploitation of Marine
Biological Resources) RI.

T16.
Upon
the completion of each work
a
report (max one A4 page) will be delivered to IMBBC describing
in-brief the analysis that was carried out, the pertinent project, as
well as the cluster usage (e.g software, CPUs/nodes, memory, storage
requirements, input data size).
