Who can get merit subsidies for time.intersect.org.au?
Researchers within Intersect's membership.
Intersect's membership consists of all NSW universities plus other independent research institutions. See the member page for a complete list.
Who needs to apply for HPC Time merit-based resource allocations?
Everyone who wants fully-subsidised Time resources over and above a start-up account (1-20k SUs per quarter). Projects with small allocations (<20k SUs per quarter) can be made at any time.
Larger allocations are available via a merit allocation process called RAR. This allocation processs is aligned with NCI's process called NCMAS so that researchers only have to do one round of applications. The call for applications occurs once a year around the end of September until the end of November. Results are announced at the end of the year.
We encourage users with significant allocation requests (> 100k Service Units / quarter) that consider their projects to meet the criteria of NCMAS, to apply for both the Intersect RAR and NCMAS to maximise your chance of receiving compute time.
How are HPC resources allocated?
Requests for merit-subsidised Intersect HPC Resources are assessed and allocated by an independent committee known as the Resource Allocation Committee, made up of representatives from each of Intersect’s member institutions.
Important factors the committee considers to determine the allocation of merit-based subsidises include the quality of the research argument, the track record of previous granted resources and the suitability of the chosen hardware and software.
Intersect allow has smaller (<20K SUs) HPC resource to allocate throughout year — get in contact if you have a small project and we will try accomodate you if the resources become availible.
How do I acknowledge or attribute fully subsidised resources?
If you have used merit-allocated resources on Orange or NCI via the Intersect partner share, we request that you acknowledge us. The proposed text is:
Computational (and/or storage) resources used in this work were provided by Intersect Australia Ltd.
The full policy can be found here: http://www.intersect.org.au/attribution-policy
Can I renew my project?
Yes. If you had a previous project with Intersect you can reapply using this form: https://nf.nci.org.au/accounts/projects_renewal/APP_form.php
Do I also need to apply for accounts?
No. The account application form is the same form as the resource request form.
What is the definition of a service unit (SU)?
A service unit, SU, is defined as 1 hour compute time on 1 core. To account for big memory usage effectively blocking the usage of all cores within a node you are charged an additional SU per 4GB memory and hour on Orange.
For example: if you use 1 core for 1 hour and 8GB memory, you are charged 2 SUs.
Raijin requires you to ask for more cores in order to get more memory for your job. Limits depend on project and queue. Use the command nf_limits on Raijin for details.
