====== Installed Software =====

==== Compilers and mpi versions ====

Various version of C/C++, Fortran, CUDA compilers and python are available on all the nodes. \\
To compile code on the nodes interactively, log into a node using interactive jobs:
<code>
bsub -q hpc_int -Is /bin/bash
</code>

**PLEASE NOTE:** Although you can compile on the User Interface, as in any other node, it is a virtual machine and not suitable for compilation, in particular GPU code; probably any CPU dependent optimizations will be lost in your executables.\\

**By default the system compilers are:**
<code>
gcc --version
gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-4)
gfortran --version
GNU Fortran (GCC) 4.4.7 20120313 (Red Hat 4.4.7-4)
</code>
If you are ok with these versions you can use them directly. \\
If you want to use a **different version** or the **CUDA compiler** or an **MPI library** you can use the Linux Environment Module tool that will set-up correctly the environment for the chosen version, i.e. you can try:

<code>
module avail
module load compilers/cuda-5.5
echo $PATH
echo $LD_LIBRARY_PATH
module list
module unload compilers/cuda-5.5
module list
echo $PATH
echo $LD_LIBRARY_PATH
</code>
