Building and Running MFIX-Exa on an ubuntu laptop

Notes

  • These are not the advised, recommended or even suggested build instructions.
    I am simply reporting what worked for me, on my laptop, running
    Ubuntu 22.04.4 LTS (Jammy Jellyfish).
  • I think these are all of the packages that I am using that are required to follow along:
    sudo apt-get update
    sudo apt-get install -y make cmake
    sudo apt-get install -y make cmake git-all
    sudo apt-get install -y gcc g++ gfortran
    sudo apt-get install -y build-essential libopenmpi-dev openmpi-bin
    sudo apt-get install -y m4
    sudo apt-get install -y vim
    
  • I’m doing this in a quad core laptop, so all make’s are with -j2. If you have more resources available, use them.
  • I initially tried ascent develop with vtk-m v2.1.0 and conduit v0.8.8.
    I was able to compile successfully, but the code hits a runtime error due to
    a missing vtk-m worklet library.

Without further ado, let’s open up a temporary directory and get started.

rm -rf tmp.build.deps
mkdir tmp.build.deps && cd tmp.build.deps

Constructive Solid Geometry (csg)

First I’ll install the dependencies for the csg-eb library.

export CSG_INSTALL_DIR=$HOME/packages/csg-eb-deps
mkdir -p $CSG_INSTALL_DIR

wget https://ftp.gnu.org/gnu/gmp/gmp-6.2.1.tar.xz

We are done building dependencies. I always super-build MFIX-Exa, so the csg-eb lib gets build right along with it. But, it’s probably not a bad idea to go ahead and build the standalone lib now too, just in case.

export CSG_LIB_DIR=$HOME/packages/csg-eb
mkdir -p $CSG_LIB_DIR

git clone https://mfix.netl.doe.gov/gitlab/exa/csg-eb.git
pushd csg-eb
mkdir build && cd build/

export Boost_INCLUDE_DIR="-I$CSG_INSTALL_DIR/include"
export CSG_DIR=$CSG_INSTALL_DIR

Running a job

I’ll use bench05 as a simple test of the executable.
First let’s make sure it runs “as-is”

cd ../benchmarks/05-cyl-fluidbed/Size0001/
ln -s ../../../build.deps/mfix
mpirun -np 1 ./mfix inputs 

You should see a bunch of screen output that ends with AMReX (id) finalized.
Unfortunately, this doesn’t test any of the dependencies that we just built against.
Use your text editor of choice to modify the inputs file to

  1. use multiple grids:
    The grid size is set to the maximum, 1024 in each direction. And the
    entire domain size is just amr.n_cell = 20 5 5. Let’s set
    amr.max_grid_size_x = 10 so that the problem is decomposed onto two grids.

  2. use the csg library:
    Fortunately, there is already a csg file of the cylindrical EB, we just need
    to enable it. Just comment in the geometry_filename keyword and comment out,
    or delete, the amrex-native EB keywords,

    mfix.geometry_filename = "geometry.csg"
    #mfix.geometry = "cylinder"
    
    #cylinder.internal_flow = true
    
    #cylinder.radius = 0.00045
    #cylinder.height = -1.0
    
    #cylinder.direction = 0
    #cylinder.center    =  0.0020  0.0005   0.0005
    
  3. use the hypre linear solvers:
    This problem is simple, so amrex’s default bicg bottom solvers work fine, but
    let’s offload to hypre just to test the build,

    mac_proj.bottom_solver   =  hypre
    nodal_proj.bottom_solver   =  hypre
    
  4. use ascent visualization:
    Add these input keywords

    mfix.ascent_int     = 10
    ascent.actions     = "ascent_actions.yaml"
    

    and create a simple ascent pipeline named ascent_actions.yaml. Here’s a simple one to
    visualize the particles looks like

    -
      action: "add_scenes"
      scenes:
        s1:
          plots:
            p1:
              type: "pseudocolor"
              field: "velz"
              points:
                radius: 50.0e-6
              min_value: -0.001
              max_value:  0.001
              color_table:
                name: "Default" 
          renders:
            r1:
              image_width: 360
              image_height: 720
              image_prefix: "vis_p_velz_%06d"
              camera:
                position: [ 0.002,  0.0005,  0.0087]
                look_at:  [ 0.002,  0.0005,  0.0005]
                up: [1, 0, 0]
                zoom: 2.2
              bg_color: [ 1.0,  1.0,  1.0]
              fg_color: [ 0.0,  0.0,  0.0]
              render_bg: "true"
              shading: "enabled"
    

Now we’re ready to re-run. This time, use two processes and let’s pipe the std out
to a screen file,

mpirun -np 2 ./mfix inputs > screen.txt

In the output you should now be able to verify that you

  • :heavy_check_mark: ran in parallel by seeing MPI initialized with 2 MPI processes
  • :heavy_check_mark: used the csg-eb library by seeing mfix.geometry_filename: geometry.csg
  • :heavy_check_mark: if you enabled TinyProfile in the build, you should see several hypre routines being hit in the profiling at the end of the screen output, such as HypreIJIface::run_hypre_setup() and HypreIJIface::run_hypre_solve()
  • :heavy_check_mark: ran with ascent in situ visualization by seeing the printed png files, e.g.,
2 Likes

update 1 - to run the benchmark inputs with csg you now need to include the input mfix.geometry = "csg" as well.

I collected all the shell command into two bash shell script: one for downloading 3rdparty packages; one for building all the dependents libs.

How to use

rm -rf tmp.build.deps
mkdir tmp.build.deps && cd tmp.build.deps

./download.deps.sh
./build.deps.sh

Then build mfix

tar xvf mfix-24-06-tar.gz
cd mfix

./buildit.sh

Shell scripts

download.deps.sh:

#!/bin/bash

# Function to retry a command until it succeeds
retry() {
  local n=1
  local max=5
  local delay=5
  while true; do
    "$@" && break || {
      if [[ $n -lt $max ]]; then
        ((n++))
        echo "Command failed. Attempt $n/$max:"
        sleep $delay;
      else
        echo "The command has failed after $n attempts."
        return 1
      fi
    }
  done

Hi, Fullmer! Would you like to share some tips on how to enable gpu computionation for mfix-exa?

yes, but I don’t have a GPU card on my ubuntu machine, so I can’t give similar specific instructions. General build instructions are here and some machine-specific instructions are here. They are a little out of date and almost certainly can’t be c&p’d on your system, but it shows you how we compile for GPUs on several HPCs.

Thanks, @wfullmer for the detailed information. It has been helpful.

Could you help with building a standalone mfix executable for a sub-case, e.g. unit-tests/chemistry?

yes, probably. I’m guessing you have already been working with @YupengXu? Perhaps he already has something in hand that is what you want? If so, it would be nice if you could post it publicly on the forum for others.

Thanks, @wfullmer … You are right, I have been working with @YupengXu. I am attaching the modified files based on our biomass pyrolysis problem. I am unable to successfully compile the case with these modifications.
