To apply, you must be a scientist in Swedish academia, at least at the level of assistant professor.
Deadlines and Decisions
Proposals are processed monthly during the year. Note that staff will be on vacation during the summer and Christmas and New Year holidays. Thus, July and December have different schedules than other months.
Projects will receive a default 500 GiB storage allocation on Centre Storage at NSC. If you need more storage, please apply for a Storage project and decline default storage from this compute proposal.
Tetralith, tetralith.nsc.liu.se, runs a CentOS 7 version of the NSC Cluster Software Environment. This means that most things are very familiar to Triolith users.
You still use Slurm (e.g sbatch, interactive, ...) to submit your jobs. ThinLinc is available on the login nodes. Applications are selected using "module".
All Tetralith compute nodes have 32 CPU cores. There will be 1832 "thin" nodes with 96 GiB of primary memory (RAM) and 60 "fat" nodes with 384 GiB. Each compute node will have a local SSD disk where applications can store temporary files (approximately 200GB per node).
All Tetralith nodes are interconnected with a 100 Gbps Intel Omni-Path network which is also used to connect the existing storage. The Omni-Path network works in a similar way to the FDR Infiniband network in Triolith (e.g with a fat-tree topology).
The Tetralith installation will take place in two phases. The first phase consist of 644 nodes and have a capacity that exceeds the current computing capacity of Triolith. The first phase was made available to users on August 23, 2018.
Triolith was turned off September 21, 2018. After this, the second phase of the Tetralith installation will begin. NSC plans to have the entire Tetralith in operation no later than December 31st (i.e for the next round of SNAC Large projects.)
If you need more than default storage, please apply for a Storage project and decline this default storage from this compute proposal.
Project storage for SNIC (Small, Medium and Large) and LiU Local projects. Centre Storage @ NSC is designed for fast access from compute resources at NSC. The purpose is to provide storage for active data for projects allocated time on compute resources at NSC.
Swedish Science Cloud (SSC) is a large-scale, geographically distributed OpenStack cloud Infrastructure as a Service (IaaS), intended for Swedish academic research provided by NAISS.
It is available free of charge to researchers at Swedish higher education institutions through open application procedures.
The SSC resources are not meant to be a replacement for NAISS supercomputing resources (HPC clusters). Rather, it should be seen as a complement, offering advanced functionality to users who need more flexible access to resources (for example more control over the operating systems and software environments), want to develop software as a service, or want to explore recent technology such as for “Big Data” (e.g. Apache Hadoop/Spark) or IoT applications.
