ADIOS2 is installed as part of the `E4S <https://e4s-project.github.io/>`_ software stack and access to adios2 is the same as access to the many other packages.

*****************************************
NERSC Perlmutter 
*****************************************

To use adios2 on Perlmutter, 

- load the e4s module
- pick your compiler environment with spack
- load adios2 with spack

.. code-block:: bash

  ~> module load e4s
    _____________________________________________________________________________________
     The Extreme-Scale Scientific Software Stack (E4S) is accessible via the Spack package manager.

     In order to access the production stack, you will need to load a spack 
     environment. Here are some tips to get started:


     'spack env list' - List all Spack environments
     'spack env activate gcc' - Activate the "gcc" Spack environment
     'spack env status' - Display the active Spack environment
     'spack load amrex' - Load the "amrex" Spack package into your user environment

     For additional support, please refer to the following references:

*****************************************
OLCF Frontier 
*****************************************

OLCF installs the E4S packages in individual modules, hence `adios2` is also available as a module.

.. code-block:: bash

  $ module avail adios2
  ----- /sw/frontier/spack-envs/base/modules/spack/cray-sles15-x86_64/cray-mpich/8.1.23-j56azw5/cce/15.0.0 -----
   adios2/2.8.1    adios2/2.8.3 (D)

  Where:
   D:  Default Module

  $ module load adios2
  $ bpls -Vv
    blps: ADIOS file introspection utility

    Build configuration:
    ADIOS version: 2.8.3
    C++ Compiler:  GNU 12.2.0 (CrayPrgEnv)
    Target OS:     Linux-5.14.21-150400.24.11_12.0.57-cray_shasta_c
    Target Arch:   x86_64

*****************************************
ALCF Aurora
*****************************************

To use adios2 on Aurora,

-	Load the default oneAPI (loaded automatically on login)
- module use /soft/modulefiles
- module load spack-pe-oneapi/0.5-rc1

This is a "metamoduile" that makes many software packages from E4S loadable as modules.

.. code-block:: bash

  $ module use /soft/modulefiles
  $ module load spack-pe-oneapi/0.5-rc1
  $ module avail adios2
