Global full waveform inversion workflow

PyperS

Introduction

Piper is yet another package for full waveform inversion studies. It features a flexible workflow manager and integration with EnTK.

The workflow of piper consists of 2 levels: stages and tasks. Stages are executed in their creation order. A stage may contain one or more tasks, which are executed in parallel.

Currently there are two options to execute the pipeline: build-in pipeline tool for small testing tasks and EnTK for large tasks.

Prerequisites

• Python 3.7 or later
