LUMI Pilot Allocations

Call for proposals: Lumi pilot user projects (Sweden)

The pan-European flagship supercomputer LUMI will be opened for customer use during the summer of 2021. Read more about LUMI’s capabilities and partitions at:

LUMI will be installed in two phases:

  • During the summer of 2021, all partitions besides the LUMI-G platform will be installed, together with the Early Access Platform for preparing applications for LUMI-G.
  • At the end of 2021 LUMI-G will be integrated into the system, and then LUMI will be in its final configuration.

The delivery acceptance of both of these phases includes a 20-day availability testing and pilot use period.

We now call for proposals for pilot projects. Each LUMI consortium country will select up to 2 projects for each phase. This call for the Swedish pilot projects is organised by The Swedish Research Council and SNIC, and it is open for Principal Investigators with experience from SNIC Large, or similar experience from other corresponding resources. Both calls open on 19 February and close on 18 March 2021 at 3pm CET. Proposals should be filled out electronically via Evaluation of the proposals is expected to be concluded no later than 9 April.

The pilot projects sought after should have the following profiles:

  • Phase 1: data-intensive computing, high-throughput computing, and high-performance data analytics (CPU-only) workloads
  • Phase 2: highly scalable GPU applications.

The intention for the first phase is to stress test the system, especially the storage systems. In the second phase, which only concerns the GPU partition, LUMI-G, the intent is to keep the GPU partition under full load and demonstrate its scalability. The availability and technical readiness of the system (e.g. installed software) is not guaranteed and unexpected maintenance breaks may occur during the piloting period.

No accounting will take place during the pilot period, and the selected pilot users are allowed and expected to use the system as much as they can. The pilot projects selected are expected to begin on 12 July, 2021 and 27 December, 2021 for the first and second phase, respectively, and expected to continue for the full 20 days of the pilot period.

The same applicant may apply for participation in both phases, minding that the project profiles are very different as described above. The different phases shall be applied for separately.

The general principle of the selection process is to favour cutting-edge research. The selected users/user groups are also expected to have the sufficient technical capability to be able to prepare for the pilot use (with support from LUMI User Support Team (LUST) and ENCCS if needed) and execute the pilots right from the beginning of the piloting phase. The pilot users are expected to report findings and feedback about the system performance, performance variations, computing environment et cetera. Previous experience from piloting of new resources will be regarded as favourable during the selection process.

The pilot applications are assessed according to the following criteria:

  • The applicant's technical capability and commitment to implement the project. Especially for the 2nd phase pilots the candidates are expected to start actively preparing for the pilot immediately after receiving a favourable evaluation.
  • Technical representativeness of the project and simulation code, i.e. impact on the purpose of the acceptance testing and future use of LUMI.
  • The scientific significance, breakthrough potential, and impact of the described project.

The scientific quality, breakthrough potential, and impact of proposals will be evaluated by the SNIC National Allocations Committee, SNAC.The evaluation of the technical feasibility will be made by LUST and SNAC Working Group. 

Contact persons will be appointed for the selected projects. LUST and ENCCS can provide consultation on application porting and optimisation, especially for the 2nd phase pilot projects. Furthermore, LUMI will facilitate the selected pilot projects with common communication platforms and virtual hackathons. ENCCS can help with the preparation of pilot applications.

How to apply for LUMI Pilots

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.

Please note that you do not apply for specific resources in this round. Your proposal is comprised of the basic information and the proposal documents.

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

2. SNIC Project Description (Maximum 2 pages)

Project description for LUMI Acceptance Test Pilots

The project description shall be max two A4 pages 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. 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 and previous pilot experience, position, and roles within the project.
  2. Implementation (approx. ¾ page)
    Describe the computational and/or data challenges. Describe technical capability, readiness, and commitment to implement the project, addressing the profile of the pilot phase as well as technical representativeness of the project, i.e. the impact on the purpose of the acceptance testing.
    Describe the codes and methods to be used, with suitable references to previous scaling and large-scale runs. Describe the application  readiness for large-scale runs. Provide a plan for the intended pilot runs in terms of expected performance and scalability.
    Assess the needed compute and storage resources and capabilities.
  3. Scientific challenges (approx. ¾ page)
    Describe the scientific significance and impact of the intended research, and how it relates to the state of the art of the scientific area and has the potential to increase the knowledge within its scientific area.
