Quick Installation

Install uv:

Linux / macOSWindows

curl -LsSf https://astral.sh/uv/install.sh | sh

Then create and activate a virtual environment and install OpenGRIS Scaler:

Linux / macOSWindows

uv venv
source .venv/bin/activate
uv pip install 'opengris-scaler[all]'

See Installation for other install choices and optional dependencies.

Start Services

Remote AWS EC2Remote AWS HPC Batch

Run the scheduler, object storage server, and ORB worker manager on an EC2 instance. Workers are provisioned automatically in the same VPC.

See ORB AWS EC2 Quickstart (EC2) for full setup instructions.

Start Compute Tasks

While Scaler provides a lower level API for submitting tasks, it’s most often used through its associated higher-level APIs: parfun and pargraph.

Make sure you get these libraries installed before running the examples below:

uv pip install numpy scipy pandas opengris-parfun pargraph

Basic examples

• Task parallelism using parfun

• Concurrent graph computation using pargraph

Additional Jupyter notebooks demonstrating real-world distributed computing use cases with Scaler, parfun, and pargraph:

• Multi-Signal Alpha Research Platform with Parfun

• Parallel Vol Surface Calibration & PDE Exotic Pricing with Parfun

• Parallel Swap Portfolio CVA with Pargraph + Parfun

• Portfolio-Level XVA Risk Computation with Pargraph
