LUMI Sweden Allocations, Closed

Calls för LUMI Sweden allocations are issued bi-annually by SNIC. The allocation periods start 1 July and 1 January for a 6- or 12-month period. The next call for LUMI Sweden is scheduled for the autumn of 2021.

During the first call, LUMI Sweden Spring 2021, the procedure will be similar to SNIC Large Spring 2021 where applicable. Please refer to the requirements for Large. The LUMI Sweden round will be further developed for future calls. For the first call, LUMI Sweden Spring 2021, the allocation period is limited to 2021, i.e. from when the resource is made available through 31 December 2021. It is allowed to apply for SNIC Large Spring 2021 and LUMI Sweden Spring 2021 simultaneously, and allocations in both rounds may be granted.

In addition to the eligibility requirements for SNIC Large, experience from SNIC Large, PRACE, or similar is required in order to be eligible for allocations in this round.

The calls for LUMI Sweden rounds are aligned in time with SNIC Large calls.

Beware that the autumn of 2021 is an installation period before the resource is made generally available in January 2022. This connotes that the system may undergo maintenance on short notice, the software stack may not have been finalised, and in particular there will be a longer maintenance window towards the year's end when the GPU partition and the network interface cards for the production environment are going to be installed.

For more information on the resource, please refer to 

LUMI consists of several partitions. This call makes available the CPU partition, LUMI-C, and the storage partitions LUMI-F, LUMI-P, and LUMI-O. The table below shows the Swedish share of the resource that is available in the call LUMI Sweden Spring 2021 (period through 31 December 2021). Compute is applied for using core hours for the entire call.

Please notice that storage has to be applied for within the call, if needed. Storage is applied for using TB hours. Flash storage, LUMI-F, is accounted at ten times the TB-hour rate, i.e. use of 1TB of Flash storage for one hour costs 10 TB hours. Lustre storage, LUMI-P, is accounted at the TB-hour rate. CEPH storage, LUMI-C, is accounted at 1/2 the TB-hour rate, i.e. use of 1TB of CEPH storage for one hour costs 0,5 TB hours. You may combine the three types of storage at your own discretion, as long as you stay within the amount granted to your project and do not exceed the quota for any of the storage types at any time. If you can justify an increased quota during the project, it is obtainable by contacting the LUMI User Support Team, LUST.

  • LUMI Sweden Spring 2021: The total number of core hours/TB hours available for this round. N.B. for the entire round, not per month!
  • Minimum: Represents the minimum allocations in core hours. An application for a LUMI Sweden allocation must include a request at or above this limit.
Resource LUMI Sweden Spring 2021 Minimum
LUMI Storage
23 800 000
12 000 000
1 500 000
no limit

1 500 000 core hours corresponds to 375 000 core hours per month, if spread out evenly during the allocation period.

This being a new round for a new resource, feedback from experiences made from the first call is especially welcome.

How to apply for LUMI Sweden

Please begin by reading the general information on how to apply for allocations on SNIC resources.

Go to the application form

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.

If you have already applied for a SNIC Large project, you may want to reuse the documents from that application.

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

2. Publication list of the principal investigator

3. SNIC Project Description (Maximum 5 pages)

Project description for LUMI Sweden

The project description shall not exceed five A4 pages (6½ if you include a Data Management Plan) set in 11pt or larger with a line spacing of at least 1.15 or similar. The disposition should follow the major topics listed here.

  1. Overview (approx. ½ page)
    Provide an abstract of the proposed research, computations, and planned analysis.
  2. Research group and management (approx. ½ page)
    Describe the complete research group that will be working on the proposed project. For each member, please specify at least the name of the member, HPC experience, position, and roles within the project. Indicate how the allocated time will be managed within the group.
  3. Implementation (approx. 1½ 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 if you have been granted time for this 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. Data management plan (approx. 1½ pages)
    Describe how your applications can make efficient use of the requested resources. Motivate and provide explicit numbers related to size, generation rate, number of files et cetera. Describe how data will be generated (codes, data type et cetera), transferred into and out of the system. Describe how data will be managed on the system, for example using ephemeral/permanent storage. Describe how your project can efficiently balance the use of high-performance storage and lower-cost storage, and how your dataflow will be set up to accommodate for that. If applicable, describe how data will be made publicly available following the end of the project.
  5. Scientific challenges (approx. 2 pages)
    Describe how the proposed project relates 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. Include a justification for the need of large-scale data/HPC.
  6. References (approx. ½ page)
    Include a list of references for the project description.
