SNAC Large, Spring 2018
The results of the Large Spring 2018 call is shown below.
The Spring LARGE 2018 call is closed as of April 13 3pm.
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.
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, Spring 2018 (period 1 July 2018 - 31 June 2019).
- Total Size: the total number of core hours/month on the resource that are available for SNIC allocations.
- Spring 2018: the total number of core hours/month that are available for LARGE allocations during the Spring 2018 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||Spring 2018||Minimum|
|C3SE||Hebbe||2 350 000||600 000||100 000|
|HPC2N||Abisko||11 473 920||2 500 000||200 000|
|HPC2N||Kebnekaise||10 470 000||4 000 000||200 000|
|Kebnekaise Large Memory||500 000||20 000|
|Lunarc||Aurora||2 592 000||500 000||100 000|
|NSC||Triolith*||11 059 200||3 600 000||120 000|
|PDC||Beskow||29 900 000||11 200 000||200 000|
|UPPMAX||Rackham||4 000 000||1 000 000||100 000|
|UPPMAX||Crex 1**||1000 TB|
* Triolith will be replaced with a new system named Tetralith. Awarded Triolith allocations will be transferred to Tetralith and users migrated. Details will be announced later.
The Tetralith installation will take place in two stages. The first stage will have a capacity that exceeds the current computing capacity of Triolith. NSC plan to have the first stage available from July 1, 2018. The second part is installed after Triolith is decommissioned and dismounted. NSC plan to have the entire Tetralith in operation by November. Existing centre storage will remain and be reconnected to Tetralith. Tetralith will be running a CentOS 7 version of the NSC Cluster Software Environment.
Tetralith will consist of 1892 servers. Each server has two Intel Xeon Gold 6130 processors providing 32 cores per server. 1832 of the servers is equipped with 96 GiB of primary memory and 60 servers with 384 GiB. All servers are interconnected with a 100 Gbit Intel Omni-Path network which is also used to connect the existing storage.
** In this round of SNAC LARGE, a storage resource has for the first time been made
available. 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
Note: 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.
CV of the PI - principal investigator (Maximum 2 pages.)
Publication list of the principal investigator
Detailed project description with list of references. (Maximum 5 pages.)
The project description may contain a section with background information, but must contain the following sections:
Describe the proposed research. Include a list of references for the description of the proposed research.
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.
Activity report. (Maximum 8 pages)
As of 2016 the requirements for reporting the activity of SNAC Large projects have changed. The below text gives updated 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.
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.
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.
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.
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: An activity report is required from the PI of the LARGE allocation after the project allocation has ended.
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.
