Parsing progress information

Oct 13, 2025 by wbrum.org 19 views

Introduction

As a user of the popular parallel computing library, parallel, you're likely no stranger to the challenges of managing complex simulations and bootstrapping processes. These tasks can be time-consuming and often require a significant amount of computational resources. In this article, we'll explore a solution to enhance the user experience by providing real-time progress tracking, making it easier to monitor and manage your simulations.

The Problem: Monitoring Progress in Parallel Computing

When running simulations or bootstrapping processes, it's essential to have a clear understanding of the progress being made. This information can help you anticipate the completion time, make adjustments to your workflow, and ensure that your resources are being utilized efficiently. However, the current implementation of parallel does not provide a built-in mechanism for tracking progress, leaving users to rely on external solutions or manual monitoring.

A Custom Solution: plprogress

To address this gap, I've developed a simple Python script, plprogress, which can be used to track the progress of parallel simulations and bootstrapping processes. This script scans the logfiles generated by parallel and provides a summary of the progress, including the number of replications completed, pending, and an estimated completion time.

How plprogress Works

The plprogress script operates by:

Scanning logfiles: The script searches for logfiles generated by parallel in the current working directory.
Parsing progress information: It extracts relevant information from the logfiles, including the number of replications completed and pending.
Calculating estimated completion time: Based on the progress information, the script estimates the time required to complete the remaining replications.
Providing a summary: The script presents a concise summary of the progress, including the number of replications completed, pending, and the estimated completion time.

Example Use Case: Integrating plprogress with Stata

To demonstrate the effectiveness of plprogress, let's consider an example use case where we integrate the script with Stata, a popular statistical software package. By running plprogress as a second script alongside Stata, we can monitor the progress of our simulations and make informed decisions about resource allocation.

Code and Availability

The plprogress script is available on GitHub, and you can access it by visiting the following link: https://github.com/fbittmann/plprogress/blob/main/plprogress.py

Integrating plprogress with parallel: A Feasibility Study

Given the complexity of the parallel source code, integrating plprogress directly into the original code may not be feasible. However, we can explore alternative approaches to achieve this integration, such as:

Modifying the parallel API: We could modify the parallel API to include a progress tracking mechanism, allowing users to access progress information programmatically.
Developing a custom plugin: We could create a custom plugin for parallel that integrates plprogress and provides a seamless user experience.

Conclusion

In this article, we've explored the challenges of monitoring progress in parallel computing and introduced a custom solution, plprogress, to address this gap. By providing real-time progress tracking, plprogress enhances the user experience and enables more efficient resource allocation. While integrating plprogress with parallel may require further investigation, we've demonstrated the feasibility of this approach and highlighted potential alternatives for achieving this integration.

Future Directions

As we continue to develop and refine plprogress, we'll focus on the following areas:

Improving accuracy: We'll work on enhancing the accuracy of the estimated completion time by incorporating more sophisticated algorithms and data analysis techniques.
Expanding compatibility: We'll explore ways to expand the compatibility of plprogress with other parallel computing libraries and frameworks.
Developing a user-friendly interface: We'll create a user-friendly interface for plprogress to make it easier for users to access and interpret progress information.
