SNIC Large


The call Fall LARGE 2019 closed on October 11.

Calls for LARGE allocations are issued twice a year by SNIC. The allocation periods start July 1st and January 1st for a 12-month period.

For instructions regarding eligibility and how to apply please read How to apply for LARGE allocations.  

The table below shows SNIC resources that are available in the call SNAC Large, Fall 2019 (period 1 January 2020 -  31 December 2020). 

  • Fall 2019: the total number of core hours/month that are available for LARGE allocations during the Fall 2019 allocation round. 
  • Minimum: Represents the upper limit on MEDIUM allocations in core hours/month. An application for a LARGE allocation must include a request above this limit for at least one resource.
Centre Resource Fall 2019 Minimum
C3SE Hebbe 600 000 100 000
HPC2N Kebnekaise 3 200 000  200 000
Kebnekaise Large Memory 450 000  20 000
Lunarc Aurora 500 000 100 000
NSC Tetralith 16 000 000 200 000
PDC Beskow 11 200 000 200 000
UPPMAX Rackham 1 000 000 100 000
UPPMAX Crex 1* 1000 TB

* Crex is the centre storage at UPPMAX, attached to the Rackham compute cluster. Proposals requesting Crex storage in SNAC LARGE must also include requests for compute resources totalling more than the limits of SNAC MEDIUM (100 kch/month), at least part of which are on Rackham.Storage at SNIC centra other than UPPMAX is handled by individual consideration by the centra.

How to apply for LARGE allocations

Please first read the general information how to apply for allocations on SNIC resources

the PI must be a senior scientist in Swedish academia, at least at the level of assistant professor (forskarassistent).

Click here to go to the application form (opens in a new window/tab)

In addition to the application form, the application must include the following appendices that must be submitted electronically through the upload facility in the online proposal submission system.

  1. CV of the PI - principal investigator (Maximum 2 pages.)

  2. Publication list of the principal investigator

  3. SNIC Project Description (Maximum 5 pages.)

    • Overview (0.5 page)
      Provide an abstract of the proposed research and computations.

    • Resource usage, codes and performance (1.5 pages)
      Describe how your applications can make efficient use of the requested resources. Give numbers and/or indicate measures of scalability and performance (for example a graph of execution time versus number of cores).

      Include records of usage only if this project is not a direct continuation of a previous one, or if you have not been granted time for a similar project(s) in previous allocation rounds.

      If the requested resources differ significantly from earlier allocations and/or used resources, please explain the difference. Also motivate if specific resources (such as large memory, GPUs, etc.) are requested.

    • Scientific challenges (2 pages)
      Describe how the proposed project relate to the state of the art of the scientific area, has the potential to increase the knowledge within its scientific area, and how the proposed project uses adequate computational methods to address scientific questions.

    • Research group and management (0.5 page)
      Describe the complete research group that will be working on the proposed project: name of member, HPC experience, position, and roles. Indicate how the allocated time will be managed within the group.

    • References (0.5 page)
      Include a list of references for the project description.

  4. Activity report. (Maximum 8 pages)
    The below text gives instructions for the activity report.
    Please note that the activity report is compulsory for all applicants. Failing to comply with the requirements will have a negative impact on your future allocations of compute time.

    • Summary
      The report must include an account of the major scientific achievements emanating from the use of the allocated SNIC resources / comparable resource outside of Sweden. If this is your first application for SNIC resources, but you have previously been using comparable resources abroad, please also provide allocation and usage statistics in the activity report.

    • Publications list
      The activity report must include a list of publications from the last two years of all publications that acknowledge the use of SNIC resources. You may include forthcoming / in press publications.

    • Academic achievements
      The activity report must include achievements such as theses defended and graduate degrees completed.

    • HPC related developments
      The activity report must include any developments related to programming, code optimization, visualization etc.

    • What not to include
      Please note that publications that do not acknowledge the use of SNIC resources shall not be included in the activity report.

    • Acknowledging SNIC
      Please note that you must give SNIC credit for research facilitated by SNIC resources.
      SNIC should be acknowledged as follows:"The computations/simulations/[SIMILAR] were performed on resources provided by the Swedish National Infrastructure for Computing (SNIC) at [CENTRE NAME (CENTRE ABBREVIATION)]."

Note: The PI must be a senior scientist in Swedish academia, at least at the level of assistant professor (forskarassistent).

Note: The entire application must be written in English.

Note: Incomplete or late proposals will be discarded.

Note: For the evaluation of applications for LARGE allocations, a peer review procedure is used. SNAC evaluates the applications and decides on the allocations. The evaluation is based on scientific merit, need for the resources, feasibility of efficient use of the requested resources, and impact. For the evaluation of an application for a LARGE allocation, SNAC may consult experts in the scientific and engineering area of the application as well as experts in applications and techniques for efficient resource utilization.

LARGE allocations are usually decided a few weeks before the start of the allocation period. It is not possible to apply for a LARGE allocation outside the regular calls. Applications outside the regular calls are normally only granted allocations of SMALL or MEDIUM size.

Minor applications for additional allocations to be added to an existing LARGE project allocation can be included.
