LBPM (Lattice Boltzmann Methods for Porous Media) is an open source software framework designed to model flow processes based on digital rock physics, and is freely available through the Open Porous Media project. Digital rock physics refers to a growing class of methods that leverage microscopic data sources to obtain insight into the physical behavior of fluids in rock and other porous materials. LBPM simulation protocols are based on two-fluid lattice Boltzmann methods, focusing in particular on wetting phenomena. The Department of Earth and Environmental Engineering and the Kelly Lab are the main users

Some modifications are needed to get the water-flooding simulation to work correct. You can start with an interactive session via Slurm's srun command and request a GPU as well as requesting at least 10 GB of memory.

srun --pty --mem=10gb -t 0-10:00 --gres=gpu:1  -A <your-account> /bin/bash

Update the wget commands as below:

Ginsburg has Singularity version 3.7.1 available. The run.sh file defaults the compute capable option as GPU_ARCH="sm70" which works on nodes with the V100 and RTX 8000. Note you can update this option to sm80 if you use a GPU node with the A40 or A100 The file also runs the mpirun command so remember to load OpenMPI as well as CUDA toolkit.

brainiak in Anaconda Python

The Brain Imaging Analysis Kit is a package of Python modules useful for neuroscience, primarily focused on functional Magnetic Resonance Imaging (fMRI) analysis. We've managed to install it in a conda environment with anaconda/3-2022.05.  After loading the module run:

conda activate /burg/opt/anaconda3-2022.05/envs/brainiak

You may have to initialize a shell first, e.g., conda init bash, note this will update your .bashrc file.

Installing Athena++

Athena++ radiation GRMHD code and adaptive mesh refinement (AMR) framework requires specific modules and can be tricky to compile. Load the following modules and respective versions and run the fllowinng commands :

The latest version of OpenMPI on Insomnia is  Ginsburg is 4.1.5a1, which is provided by Nvidia Mellanox and optimized for the MOFED stackthe MOFED stack, and is installed on each compute node to increase performance. You will receive the following warnings when using mpirun/mpiexec:

...

The library attempted to open the following supporting CUDA libraries, but each of them failed. CUDA-aware support is disabled.
libcuda.so.1: cannot open shared object file: No such file or directory
libcuda.dylib: cannot open shared object file: No such file or directory
/usr/lib64/libcuda.so.1: cannot open shared object file: No such file or directory
/usr/lib64/libcuda.dylib: cannot open shared object file: No such file or directory

If you are not interested in CUDA-aware support, then run with --mca opal_warn_on_missing_libcuda 0 to suppress this message. If you are interested in CUDA-aware support, then try setting LD_LIBRARY_PATH to the location of libcuda.so.1 to get passed this issue.

You can pass this option:

--mca 

If you are not interested in CUDA-aware support, then run with --mca opal_warn_on_missing_libcuda

RStudio in a Singularity container

On Ginsburg, rstudio can be loaded by leveraging an interactive session, i.e., srun, and using a Singularity container via the Rocker Project which provides containers from where this tutorial comes . First you will need to download the Singularity image. This will require two terminal sessions. One session will be used to connect to a compute host and run rstudio. The other terminal session will be used to initiate SSH Port Forwarding/Tunneling to access the resource. The first step is to request an interactive session so you can run rstudio server from a compute node as follows. Please be sure to change your group as noted by "-A".

srun -X -A <GROUP> --pty -t 0-01:00 -X /bin/bash

Load the Singularity module:

module load singularity

This next step will take a few minutes and will only need to be done the first time you launch this application. On subsequent sessions you skip this step as the container is downloaded:

singularity pull --name rstudio.simg docker://rocker/rstudio:4.3.1

In order for RStudio to start in a browser via an interactive session you will need the IP address of the compute node. Note that the IP below will likely be different for you:

IP_ADDR=`hostname -i`
echo $IP_ADDR
10.197.16.39

From RStudio 4.2 and later, some added security features require binding of a locally created database file to the database in the container. Don't forget to change the password.

mkdir -p run var-lib-rstudio-server

printf 'provider=sqlite\ndirectory=/var/lib/rstudio-server\n' > database.conf

PASSWORD='CHANGEME' singularity exec \
   --bind run:/run,var-lib-rstudio-server:/var/lib/rstudio-server,database.conf:/etc/rstudio/database.conf \
   rstudio.simg \
   /usr/lib/rstudio-server/bin/rserver --auth-none=0 --auth-pam-helper-path=pam-helper --server-user=$USER

This will run the Rstudio server in a Singularity container. 0 to suppress this message. If you are interested in CUDA-aware support, then try setting LD_LIBRARY_PATH to the location of libcuda.so.1 to get passed this issue.

You can pass this option:

--mca opal_warn_on_missing_libcuda 0

RStudio in a Singularity container

First you will need to download the Singularity image. This will require two terminal sessions. One session will be used to connect to a compute host and run rstudio. The other terminal session will be used to initiate SSH Port Forwarding/Tunneling to access the resource. The first step is to request an interactive session so you can run rstudio server from a compute node as follows. Please be sure to change your group as noted by "-A".

srun -X -A <GROUP> --pty -t 0-02:00 -X /bin/bash

OR, if you want a GPU node

srun -X -A <GROUP> --pty -t 0-02:00 -X --gres=gpu:1 /bin/bash

NEXT, a number of steps need to be done that have been collected into a simple script.

Type "RSserver.sh" (without the quotes) to execute the container setup script. For those interested, the script echos the commands it's running as it runs them.

PART 2:  Port forwarding and access from your browser

The Rstudio server is now running in a container in one window.  Now you will open another window and create a Port Forwarding connection so your web browser will be able to connect to a port on your local machine, that forwards the connection to the remote container.

If you're on a Mac or Linux machine, open a second Terminal and start the RStudio rserver session using Port Forwarding to connect a local port on your computer to a remote one on Ginsburg. rserver port forwarding with the below command:

ssh -Nf -L 8787:10.197.16.39:8787 myUNI@burg.rcs.columbia.edu  .16.39:8787 myUNI@burg.rcs.columbia.edu    <-- the "10.197.16.39" IP number is ONLY for demonstration. The above script will have given you the real IP you will be using.

The above Port Forwarding line works on Linux/Unix/MacOS, or any virtual machine running Linux. For Windows, we are assuming you are using PuTTY and the above line would be accomplished using the alternative steps below:

...

Next, use a web browser to connect to to your locally forwarded port.

In any web browser, e.g., Google Chrome, Safari or Edge, enter localhost:8787 (or a different number after the colon, if you received an error above and had to choose another port).

The login screen for RStudio will appear and you enter your UNI (without the @columbia.edu) and whatever password you put from the above example (where it says CHANGME). If you need a session that last longer than an hour you can add --auth-timeout-minutes=0 --auth-stay-signed-in-days=30 to the end of the above singularity. command. @columbia.edu) and whatever password you entered in the setup script.

A sample Slurm bash script is available at Rocker Project's Singularity page. If you run into an error such as [rserver] ERROR system error 98 (Address already in use), you can specify the port number as an additional option, e.g.,  --www-port 8788. The new command could look like this:

mkdir -p run var-lib-rstudio-server

printf 'provider=sqlite\ndirectory=/var/lib/rstudio-server\n' > database.conf

PASSWORD='CHANGEME' singularity exec \
   --bind run:/run,var-lib-rstudio-server:/var/lib/rstudio-server,database.conf:/etc/rstudio/database.conf \
   rstudio.simg \
   /usr/lib/rstudio-server/bin/rserver --www-port 8788 --auth-none=0 --auth-pam-helper-path=pam-helper --server-user=$USER

***IMPORTANT NOTE***

When you are finished with RStudio remember to stop the Singularity session via ctl-c, and you can kill the SSH forwarding session by finding the process ID (PID) with the following command, noting that the PID is the second column:

ps -ef | grep 8787
  503 82438     1   0 10:56AM ??         0:00.31 ssh -Nf -L 8787:10.197.16.39:8787 myUNI@burg.rcs.columbia.edu
kill -9 82438

Visual Studio Code Server

Visual Studio Code is an Integrated Development Environment that some like to use on their laptops. If you are familiar with that, the HPC has a server-side version hosted on the compute nodes (NOT the login nodes) for users to connect their local VS Code application on their laptop to Ginsburg and open files from their Ginsburg folder directly.  To use it, do the following:

After logging into Ginsburg, start an srun session to a CPU or GPU node of your choice:

srun --pty -t 0-01:00  -A <ACCOUNT> /bin/bash

     OR, if you need a GPU

srun --pty -t 0-01:00 --gres=gpu:1 -A <ACCOUNT> /bin/bash
