Running BOINC Linux: A Step-by-Step Guide

BOINC (Berkeley Open Infrastructure Network Computing) is a popular platform for distributed computing, allowing users to contribute their computer's processing power to various scientific projects. In this article, we will explore the process of setting up and running multiple instances of BOINC on a Linux system.

Troubleshooting Common Issues

Before diving into the setup process, it's essential to address common issues that may arise when running BOINC. One such issue is the inability to reply to a previous thread due to it being locked. To overcome this, create a new topic or seek assistance from the community forum.

Setting Up Multiple Instances of BOINC

To set up multiple instances of BOINC, follow these steps:

1. Create a new directory for each instance in your home directory and name it accordingly (e.g., `BOINC-40000`).

2. Copy the `cc_config.xml` file from the USB stick to the newly created directory.

3. Populate the sub-folders with the same `cc_config.xml` files and empty `gui_rpc_auth.cfg` files.

4. Make a new folder in your home directory named `BOINC` and place all instances within it.

Running Multiple Instances

To run multiple instances of BOINC, you can use the following command:

`/usr/bin/boinc -daemon -allow_multiple_clients -gui_rpc_port 40000 -dir ~/BOINC/40000`

This command will start a new instance of BOINC with the specified port and directory.

Managing Tasks

To manage tasks across multiple instances, you can use the `boinctasks` and `boinccmd` commands. These tools allow you to view the current status of tasks on each instance and control their execution.

Scripting for Automation

You can also automate various tasks using scripting languages like Python or shell scripts. For example, you can create a script that switches between instances as soon as a task is completed.

Advantages of Running Multiple Instances

Running multiple instances of BOINC offers several advantages, including:

1. Faster Work Completion: By running multiple instances, you can complete work faster and unattended.

2. Improved Resource Utilization: You can divide your computer into smaller, independent instances, making it suitable for projects with slow scheduler assignment.

3. Flexibility: With separate instances, you can run CPU and GPU tasks simultaneously or switch between them seamlessly.

Running multiple instances of BOINC on Linux is a powerful way to contribute to various scientific projects while maximizing your computer's processing power. By following the steps outlined in this article, you can set up and manage multiple instances with ease, ensuring efficient and effective computing for distributed research efforts.
