History

BOINC was originally developed to manage the SETI@home project. David P. Anderson has said that he chose its name because he wanted something that was not "imposing", but rather "light, catchy, and maybe - like '

projects, and not designed with a high level of security. As a result, some participants in the project attempted to cheat the project to gain "credits", while others submitted entirely falsified work. BOINC was designed, in part, to combat these security breaches. The BOINC project started in February 2002, and its first version was released on April 10, 2002. The first BOINC-based project was Predictor@home, launched on June 9, 2004. In 2009, AQUA@home deployed multi-threaded CPU applications for the first time, followed by the first

application in 2010. As of 15 August 2022, there are 33 projects on the official list. There are also, however, BOINC projects not included on the official list. Each year, an international BOINC Workshop is hosted to increase collaboration among project administrators. In 2021, the workshop was hosted virtually. While not affiliated with BOINC officially, there have been several independent projects that reward BOINC users for their participation, including Charity Engine (sweepstakes based on processing power with prizes funded by private entities who purchase computational time of CE users), Bitcoin Utopia (now defunct), and Gridcoin (a blockchain which mints coins based on processing power).

to perform scientific computing. In 2008, BOINC's website announced that Nvidia had developed a language called CUDA that uses GPUs for scientific computing. With NVIDIA's assistance, several BOINC-based projects (e.g., MilkyWay@home. SETI@home) developed applications that run on NVIDIA GPUs using CUDA. BOINC added support for the ATI/ AMD family of GPUs in October 2009. The GPU applications run from 2 to 10 times faster than the former CPU-only versions. GPU support (via

Mobile application

A BOINC app also exists for Android, allowing every person owning an Android device – smartphone, tablet and/or Kindle – to share their unused computing power. The user is allowed to select the research projects they want to support, if it is in the app's available project list. By default, the application will allow computing only when the device is connected to a WiFi network, is being charged, and the battery has a charge of at least 90%. Some of these settings can be changed to users needs. Not all BOINC projects are available and some of the projects are not compatible with all versions of Android operating system or availability of work is intermittent. Currently available projects are Asteroids@home, Einstein@Home, LHC@home, Moo! Wrapper, Rosetta@home, World Community Grid and . As of September 2021, the most recent version of the mobile application can only be downloaded from the BOINC website or the F-Droid repository as the official Google Play store does not allow downloading and running executables not signed by the app developer and each BOINC project has their own executable files.

User interfaces

BOINC can be controlled remotely by

) of the Simplified GUI is user-customizable, in that users can create their own designs.

Account managers

A BOINC Account Manager is an application that manages multiple BOINC project accounts across multiple computers (CPUs) and operating systems. Account managers were designed for people who are new to BOINC or have several computers participating in several projects. The account manager concept was conceived and developed jointly by GridRepublic and BOINC. Current and past account managers include: * BAM! (BOINC Account Manager) (The first publicly available Account Manager, released for public use on May 30, 2006) * GridRepublic (Follows the ideas of simplicity and neatness in account management) * Charity Engine (Non-profit account manager for hire, uses prize draws and continuous charity fundraising to motivate people to join the grid) * Science United (An account manager designed to make BOINC easier to use which automatically selects vetted BOINC projects for users based on desired research areas such as "medicine" or "physics") * Dazzler (Open-source Account Manager, to ease institutional management resources)

Credit system

* The BOINC Credit System is designed to avoid bad hardware and cheating by validating results before granting credit. * The credit management system helps to ensure that users are returning results which are both statistically and scientifically accurate. * Online volunteer computing is a complicated and variable mix of long-term users, retiring users and new users with different personal aspirations.

Projects

BOINC is used by many groups and individuals. Some BOINC projects are based at universities and research labs while others are independent areas of research or interest.
