Paraview is an open-source, multi-platform data analysis and visualization application.

The information here is applicable to LSU HPC and LONI systems.
SoftEnv is a utility that is supposed to help users manage complex user environments with potentially conflicting application versions and libraries.
System Default Path
When a user logs in, the system /etc/profile or /etc/csh.cshrc (depending on login shell, and mirrored from csm:/cfmroot/etc/profile) calls /usr/local/packages/softenv-1.6.2/bin/use.softenv.sh to set up the default path via the SoftEnv database.
SoftEnv looks for a user's ~/.soft file and updates the variables and paths accordingly.
Viewing Available Packages
Using the softenv command, a user may view the list of available packages. Currently, it can not be ensured that the packages shown are actually available or working on the particular machine. Every attempt is made to present an identical environment on all of the LONI clusters, but sometimes this is not the case.
$ softenv These are the macros available: * @default These are the keywords explicitly available: +amber-8 Applications: 'Amber', version: 8 Amber is a +apache-ant-1.6.5 Ant, Java based XML make system version: 1.6. +charm-5.9 Applications: 'Charm++', version: 5.9 Charm++ +default this is the default environment...nukes /etc/ +essl-4.2 Libraries: 'ESSL', version: 4.2 ESSL is a sta +gaussian-03 Applications: 'Gaussian', version: 03 Gaussia ....
Listing of Available Packages
For a more accurate, up to date list, use the softenv command.
Currently there are some caveats to using this tool.
- packages might be out of sync between what is listed and what is actually available
- resoft and soft utilities are not; to update the environment for now, log out and login after modifying the ~/.soft file.
softenv is available on all LSU HPC and LONI clusters to all users in both interactive login sessions (i.e., just logging into the machine) and the batch environment created by the PBS job scheduler on Linux clusters and by loadleveler on AIX clusters..
This information can be viewed using the softenv command:
Managing Environment with SoftEnv
The file ~/.soft in the user's home directory is where the different packages are managed. Add the +keyword into your .soft file. For instance, ff one wants to add the Amber Molecular Dynamics package into their environment, the end of the .soft file should look like this:
To update the environment after modifying this file, one simply uses the resoft command:

Sample usage for remote visualization:
Start ParaView server pvserver on the cluster using compute node, do *not* start pvserver from the
head node, e.g.:
qsub -I -l nodes=1:ppn=20,walltime=1:00:00 -q workq -A your_allocation_nameAfter you get the interactive session, start your pvserver from the *compute node*, e.g. smicXXX:
module load paraview/4.3.1/INTEL-140-MVAPICH2-2.0 mpirun -np 8 pvserver --server-port=11111*For unknown reason you might need to limit the number of pvserver process to 8
Establish an SSH tunnel:
Use the following command from your *local* terminal, note that the compute node number smicXXX should be the name of your compute node:
ssh -L11111:smicXXX:11111 -N email@example.comType your password and leave the terminal open.
Connect to the remote server using ParaView on your desktop:
Start the same version of paraview as installed on cluster, e.g. Pavaview 4.3.1 from your *local* terminal and use File > Connect to the forwarded localhost port.
