MEDIUM allocations are available via a yearly round (January 1- December 31). MEDIUM allocations can be requested at any time during this period via SUPR.
MEDIUM allocations are not granted for projects that have a LARGE allocation.
This category is for allocations up to a maximum size (core hours/month). The maximum size of a MEDIUM allocation varies for each resource. The total size of all MEDIUM allocations granted to you can maximally amount to 150%. For example, 80% of the maximum size of a MEDIUM allocation of one resource and 70% of the maximum size of a MEDIUM allocation of another resource.
For MEDIUM applications a technical evaluation is performed as detailed in the SNIC guidelines for resource allocation. The evaluation is performed locally at the SNIC center where the resource is located.
The table below summarizes the resources that are available for MEDIUM allocations during 2018. The unit used is: core hours per month (ch/m).
- Total Size: the total number of core hours/month on the resource that are available for SNIC allocations.
- MEDIUM 2018: the total number of core hours/month that are available for MEDIUM allocations during 2018.
- MEDIUM Limit: the upper limit on a MEDIUM allocation in core hours/month for that resource.
The table below summarizes the SNIC resources that are available for MEDIUM allocations during 2018. The unit used are core hours per month (ch/m).
|Centre||Resource||Total size||MEDIUM Limit|
|C3SE||Hebbe||1 100 000||100 000|
Kebnekaise Large Memory
1 200 000
2 000 000
|Lunarc||Aurora||1 100 000||100 000|
|NSC||Triolith*||3 600 000||120 000|
|PDC||Beskow||7 800 000||200 000|
|UPPMAX||Rackham||2 000 000||100 000|
*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.

How to apply for MEDIUM allocations
If you are a researcher affiliated with a Swedish higher-education institution, you can apply for a project in via SUPR, SNIC’s project management system.
The PI must be a senior scientist in Swedish academia, at least at the level of assistant professor (forskarassistent).
To apply for a new project you need to complete the following steps:
- Register a new “Person” (only if this is your first SNIC project).
- Log into SUPR using your new credentials.
- Create a project proposal using the round called “SNAC Medium, [yyyy]“.
- Sign the SNIC User Agreement.
Step 4 is important but easy to forget. Without it your account/project will not be created. If you have SWAMID, you can sign the User Agreement directly in the SUPR WebUI. If not, you need to send in the form via regular mail.
Once your project has been approved, you will receive an email with further instructions on how to log in etc.
Applications for MEDIUM allocations are evaluated by the centre(s) that host(s) the resource(s) on which the allocation(s) is/are requested. The evaluation is carried out by application experts and assesses the feasibility of using the requested resources efficiently. The evaluation process will normally finish in two weeks.
