After logging in, you may want to configure the environment. Write your preferred path definitions, aliases, functions and module loads in the .bashrc file
```console
$cat ./bashrc
#./bashrc
#Source global definitions
if [ -f /etc/bashrc ];then
. /etc/bashrc
fi
#User specific aliases and functions
alias qs='qstat -a'
module load PrgEnv-gnu
#Display information to standard output - only in interactive ssh session
if [ -n "$SSH_TTY" ]
then
module list #Display loaded modules
fi
```
!!! note
Do not run commands outputting to standard output (echo, module list, etc) in .bashrc for non-interactive SSH sessions. It breaks fundamental functionality (SCP, PBS) of your account! Consider utilization of SSH session interactivity for such commands as stated in the previous example.
## Application Modules
In order to configure your shell for running particular application on Anselm we use Module package interface.
!!! note
The modules set up the application paths, library paths and environment variables for running particular application.
We have also second modules repository. This modules repository is created using tool called EasyBuild. On Salomon cluster, all modules will be build by this tool. If you want to use software from this modules repository, please follow instructions in section [Application Modules Path Expansion](environment-and-modules/#application-modules-path-expansion).
The modules may be loaded, unloaded and switched, according to momentary needs.
To check available modules use
```console
$ml av
```
To load a module, for example the octave module use
```console
$ml octave
```
loading the octave module will set up paths and environment variables of your active shell such that you are ready to run the octave software
To check loaded modules use
```console
$ml
```
To unload a module, for example the octave module use
```console
$ml -octave
```
Following modules set up the development environment
PrgEnv-gnu sets up the GNU development environment in conjunction with the bullx MPI library
PrgEnv-intel sets up the INTEL development environment in conjunction with the Intel MPI library
## Application Modules Path Expansion
All application modules on Anselm cluster (and further) will be build using tool called [EasyBuild](http://hpcugent.github.io/easybuild/"EasyBuild").
This command expands your searched paths to modules. You can also add this command to the .bashrc file to expand paths permanently. After this command, you can use same commands to list/add/remove modules as is described above.
#load default intel compilator !!! is not recommended !!!
ml intel
#Display information to standard output - only in interactive ssh session
if [ -n "$SSH_TTY" ]
then
module list #Display loaded modules
ml #Display loaded modules

### EasyBuild Toolchains
As we wrote earlier, we are using EasyBuild for automatized software installation and module creation.
EasyBuild employs so-called **compiler toolchains** or, simply toolchains for short, which are a major concept in handling the build and installation processes.
A typical toolchain consists of one or more compilers, usually put together with some libraries for specific functionality, e.g., for using an MPI stack for distributed computing, or which provide optimized routines for commonly used math operations, e.g., the well-known BLAS/LAPACK APIs for linear algebra routines.
For each software package being built, the toolchain to be used must be specified in some way.
The EasyBuild framework prepares the build environment for the different toolchain components, by loading their respective modules and defining environment variables to specify compiler commands (e.g., via `$F90`), compiler and linker options (e.g., via `$CFLAGS` and `$LDFLAGS`), the list of library names to supply to the linker (via `$LIBS`), etc. This enables making easyblocks largely toolchain-agnostic since they can simply rely on these environment variables; that is, unless they need to be aware of, for example, the particular compiler being used to determine the build configuration options.
Recent releases of EasyBuild include out-of-the-box toolchain support for:
* various compilers, including GCC, Intel, Clang, CUDA
* common MPI libraries, such as Intel MPI, MPICH, MVAPICH2, Open MPI
* various numerical libraries, including ATLAS, Intel MKL, OpenBLAS, ScaLAPACK, FFTW
On Salomon, we have currently following toolchains installed:
