This page describes the building of the CMIP5 configuration of the NorESM (NorESM) model on NSC's triolith system (triolith). Triolith consists of 1200 HP SL230s compute nodes is equipped with two Intel E5-2660 (2.2 GHz Sandybridge) processors with 8 cores each, i.e 16 cores per node. Triolith is equipped with a fast interconnect (Infiniband from Mellanox (FDR IB, 56 Gb/s) in a 2:1 blocking configuration) for high performance for parallel applications.

Triolith is a SNIC-funded system, and computing time on Triolith is exclusively allocated to SNIC projects (Large, Medium and Small). See [1] and [2] for information on how to apply for a SNIC project. Contact: support@nsc.liu.se.

CESM1 unix group on triolith

If you are going to run the NorESM model on triolith, you should join the 'cesm1' unix group on triolith. This is not absolutely necessary but being a member allows access to shared storage space on /nobackup/global/proj/cesm1/NorESM where pre-downloaded initial data and ancillary files are stored. Email support@nsc.liu.se to request membership to the cesm1 unix group. Please note: Files that you copy to the shared /nobackup/global/proj/cesm1 will be charged to your space allocation on triolith.
