GNU compiler collection

The GNU compiler collection (GCC) is a compiler collection for a number of languages including C, C++ and Fortran. It also includes associated libraries. The exact contents included in this package varies between releases, so please refer to the GCC documentation and if in doubt contact the individual centres for versions and details.

Availability

Resource	Centre	Description
Alarik	LUNARC	throughput cluster resource of 40 TFLOPS
Aurora	LUNARC	throughput/general purpose cluster resource
Erik	LUNARC	Prototype system featuring 68 Nvidia Tesla K20m GPU cards and 2 Xeon Phi cards
Platon	LUNARC	throughput cluster resource of 26 TFLOPS
Triolith	NSC	Capability cluster with 338 TFLOPS peak and 1:2 Infiniband fat-tree

Tips and tricks

Most SNIC-clusters use Linux for their operating systems. These typically include a version of the GNU compiler collection for direct access. Since this version is typically quite old, users are highly advised to load a module with a more modern version of the GNU compiler collection.
