SNIC Large

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

The table below summarizes the SNIC resources that were available for LARGE allocations in the call Autumn 2017 (period 1 January 2017 - 31 December 2018). A new round will be announced during the spring of 2018.

  • Total Size: the total number of core hours/month on the resource that are available for SNIC allocations.
  • Autumn 2017: the total number of core hours/month that are available for LARGE allocations during the Autumn 2017 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 Total Size Autumn 2017 Minimum
C3SE Hebbe 2 350 000 600 000 100 000
HPC2N Abisko 11 473 920 2 500 000 160 000
HPC2N Kebnekaise 10 470 000 3 500 000  200 000
Kebnekaise Large Memory 350 000  20 000
Lunarc Aurora 2 592 000 600 000 100 000
NSC Triolith* 17 510 400 6 000 000 200 000
PDC Beskow 29 900 000 11 200 000 200 000
UPPMAX Rackham 4 000 000 650 000 80 000
* Please note that Triolith will be replaced with a new resource during 2018. NSC currently plan for the replacement to take place in Q3, 2018. At that point project allocations will be scaled and transfered to the new resource. Installation of the new system is likely to be done in stages with an overlap in operation between parts of the new system and parts of Triolith.

How to apply for LARGE allocations

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

Calls for proposals for LARGE allocations are issued twice per year.

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

Incomplete or late proposals will be discarded.

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. Detailed project description with list of references. (Maximum 5 pages.)

    The project description must contain the following sections:

    • Background information. This is optional. 

    • Scientific content. Describe the proposed research.

    • Requested resources. Describe how your application can make efficient use of the requested resources. Give numbers and/or indicate measures of scalability and performance (e.g., a graph of execution time vs. number of cores). Include records of usage if you have been granted time for this project (or a similar project) in previous allocation rounds. If the requested time differs significantly from earlier allocations and/or used time, please explain the difference.

  4. Activity report. (Maximum 6-8 pages.)
    The below text gives updated instructions for the compulsory activity report.

    • Summary
      The activity report shall describe SNIC-related activities during the last two years. The report must include a summary of all major results of the computing time allocated on SNIC resources.

    • 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)]."

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.

Note: The entire application must be written in English.

Note: An activity report is required from the PI of the LARGE allocation after the project allocation has ended.
