Materials Science Research Environment - Getting Started

Time to Complete: 20 minutes Cost: $14-22 for tutorial Skill Level: Beginner (no cloud experience needed)

What You’ll Build

By the end of this guide, you’ll have a working materials science research environment that can:

Run molecular dynamics simulations with LAMMPS
Perform density functional theory calculations with Quantum ESPRESSO
Analyze material properties and crystal structures
Handle high-performance computing with parallel processing

Meet Dr. Ahmed Hassan

Dr. Ahmed Hassan is a materials scientist at MIT. He designs new battery materials but waits 12-15 days for supercomputer access. Each simulation takes weeks to queue, delaying critical energy storage breakthroughs.

Before: 15-day waits + 24-hour simulation = 16 days per material After: 15-minute setup + 8-hour simulation = same day results Time Saved: 94% faster research cycle Cost Savings: $1,500/month vs $5,000 supercomputer allocation

Skills Needed

Basic computer use (creating folders, installing software)
Copy and paste commands
No cloud or materials science experience required

Step 1: Install AWS Research Wizard

Choose your operating system:

macOS/Linux

curl -fsSL https://install.aws-research-wizard.com | sh

Windows

Download from: https://github.com/aws-research-wizard/releases/latest

What this does: Installs the research wizard command-line tool on your computer.

Expected result: You should see “Installation successful” message.

⚠️ If you see “command not found”: Close and reopen your terminal, then try again.

Step 2: Set Up AWS Account

If you don’t have an AWS account:

Go to aws.amazon.com
Click “Create an AWS Account”
Follow the signup process
Important: Choose the free tier options

What this does: Creates your personal cloud computing account.

Expected result: You receive email confirmation from AWS.

💰 Cost note: Account creation is free. You only pay for resources you use.

Step 3: Configure Your Credentials

aws-research-wizard config setup

The wizard will ask for:

AWS Access Key: Found in AWS Console → Security Credentials
Secret Key: Created with your access key
Region: Choose us-east-1 (recommended for materials science with best HPC performance)

What this does: Connects the research wizard to your AWS account.

Expected result: “✅ AWS credentials configured successfully”

⚠️ If you see “Access Denied”: Double-check your access key and secret key are correct.

Step 4: Validate Your Setup

aws-research-wizard deploy validate --domain materials_science --region us-east-1

What this does: Checks that everything is working before we spend money.

Expected result:

✅ AWS credentials valid
✅ Domain configuration valid: materials_science

NIST materials data: ~1.8 GB (experimental material properties)
Sample crystal structures: ~300 MB (CIF files for common materials)
Total download: ~4.6 GB
Estimated time: 8-12 minutes on typical broadband

# Create working directory
mkdir ~/materials-tutorial
cd ~/materials-tutorial

# Download real materials data from AWS Open Data
echo "Downloading Materials Project crystal structures (~2.5GB)..."
aws s3 cp s3://materialsproject-build/mp_all.json . --no-sign-request

echo "Downloading NIST materials database (~1.8GB)..."

cat > aluminum_scf.in << 'EOF'
&control
    calculation = 'scf'
    restart_mode = 'from_scratch'
    pseudo_dir = './'
    outdir = './out'
    prefix = 'aluminum'
/
&system
    ibrav = 2
    celldm(1) = 7.653
    nat = 1
    ntyp = 1
    ecutwfc = 30.0
    occupations = 'smearing'
    smearing = 'gaussian'
    degauss = 0.05
/
&electrons
    conv_thr = 1.0d-8
    mixing_beta = 0.7

EOF

# Download aluminum pseudopotential
wget -O Al.pz-vbc.UPF "https://www.quantum-espresso.org/upf_files/Al.pz-vbc.UPF"

# Create output directory
mkdir -p out

echo "Running DFT calculation for aluminum..."
mpirun -np 4 pw.x < aluminum_scf.in > aluminum_scf.out

echo "✅ Quantum chemistry calculation completed!"

# Show key results
echo "=== Electronic Structure Results ==="
grep -A 5 "total energy" aluminum_scf.out || echo "Calculation still running or incomplete"
grep -A 3 "convergence has been achieved" aluminum_scf.out || echo "Check convergence status"

What this does: Calculates the electronic structure of aluminum using density functional theory.

Expected result: Shows total energy and electronic properties of aluminum.

Step 9: Using Your Own Materials Science Data

Instead of the tutorial data, you can analyze your own materials science datasets:

Upload Your Data

# Option 1: Upload from your local computer
scp -i ~/.ssh/id_rsa your_data_file.* ec2-user@12.34.56.78:~/materials_science-tutorial/

# Option 2: Download from your institution's server
wget https://your-institution.edu/data/research_data.csv

# Option 3: Access your AWS S3 bucket
aws s3 cp s3://your-research-bucket/materials_science-data/ . --recursive

Common Data Formats Supported

Crystal structures (.cif, .pdb): Atomic arrangements and lattice parameters
Spectroscopy data (.csv, .jdx): X-ray, NMR, and other characterization
Microscopy images (.tif, .dm3): SEM, TEM, and optical microscopy
Mechanical data (.csv, .txt): Stress-strain curves and material properties
Computational data (.vasp, .lammps): Simulation inputs and outputs

Replace Tutorial Commands

Simply substitute your filenames in any tutorial command:

# Instead of tutorial data:
python3 materials_analysis.py sample_data.cif

# Use your data:
python3 materials_analysis.py YOUR_MATERIAL.cif

Data Size Considerations

Small datasets (<10 GB): Process directly on the instance
Large datasets (10-100 GB): Use S3 for storage, process in chunks
Very large datasets (>100 GB): Consider multi-node setup or data preprocessing

Step 10: Monitor Your Costs

Check your current spending:

exit  # Exit SSH session first
aws-research-wizard monitor costs --region us-east-1

Expected result: Shows costs so far (should be under $12 for this tutorial)

Step 11: Clean Up (Important!)

When you’re done experimenting:

aws-research-wizard deploy delete --region us-east-1

Type y when prompted.

What this does: Stops billing by removing your cloud resources.

💰 Important: Always clean up to avoid ongoing charges.

Expected result: “🗑️ Deletion completed successfully”

Understanding Your Costs

What You’re Paying For

Compute: $1.36 per hour for HPC instance while environment is running
Storage: $0.10 per GB per month for simulation data you save
Data Transfer: Usually free for materials science amounts

Cost Control Tips

Always delete environments when not needed
Use spot instances for 60% savings (advanced)
Store large simulation datasets in S3, not on the instance
Use parallel processing efficiently to reduce simulation time

Typical Monthly Costs by Usage

Light use (20 hours/week): $400-700
Medium use (5 hours/day): $800-1300
Heavy use (10 hours/day): $1600-2600
