High Performance Computing Center North
Intel Xeon Phi x200, codename Knights Landing (KNL), is second generation MIC architecture product from Intel. At HPC2N 36 nodes, as a part of Kebnekaise, are equipped with Intel Xeon Phi 7250 CPUs. See our description of Intel Knight Landing for more information about the nodes.
At a high level there are three key aspects to achieving code performance on KNL:
NOTE: If you have read the official EasyBuild instructions there will have been mention of a configuration file. When installing software as a user, you do NOT need an EasyBuild configuration file, and it can even cause problems to have one.
This guide will let you install software (and create a module for easy loading) to your $HOME/Public directory, under a subdirectory called easybuild.
VASP has been built in both a normal CPU-only version and a GPU-enabled version.
Depending on which toolchain is loaded one or the other is available.
Use ml spider vasp to see which versions are available, and then look at the specific versions with ml spider VASP/<some-version>, to see which toolchains are available.

In this section you will find information about some of the installed software and applications on Kebnekaise at HPC2N.
It is highly recommended to read more about using modules on Kebnekaise at the Accessing software on Kebnekaise page before continuing.
This page is about software libraries. The libraries on HPC2N systems includes parallel communications libraries (MPI) as well as various mathematical libraries, including MKL. More detailed documentation on the libraries available follows below.
There are compilers available for Fortran 77, Fortran 90, Fortran 95, C, and C++. The compilers can produce both general-purpose code and architecture-specific optimized code to improve performance (loop-level optimizations, inter-procedural analysis and cache optimizations).
Kebnekaise is the latest supercomputer at HPC2N. It is named after the massif of the same name, which has some of Sweden's highest mountain peaks (Sydtoppen and Nordtoppen). Just as the massif, the supercomputer Kebnekaise is a system with many faces.
