World Community Grid uses BOINC to accelerate science by creating a supercomputer empowered by a global community of volunteers.
World Community Grid (WCG) is a volunteer computing platform dedicated to humanitarian and biomedical scientific research. It harnesses the idle processing power of everyday devices (personal computers, laptops, Android smartphones, and Raspberry Pi systems) to perform large-scale scientific calculations that would otherwise require decades of supercomputing time. Since its founding in 2004, the project has expanded to cover diseases including HIV/AIDS, cancer, tuberculosis, dengue fever, Ebola, Zika virus, and COVID-19, as well as research into clean energy, water purification, food security, and climate science.[1]
Why World Community Grid?
World Community Grid began on November 16, 2004, as a philanthropic initiative of IBM Corporate Social Responsibility, the corporate social responsibility and philanthropy division of IBM.[2] The project was inspired by a successful predecessor: in 2003, IBM and other partners sponsored the United Devices Smallpox Research Grid Project, which used a distributed computing grid to screen 35 million potential drug molecules against several smallpox proteins. In the first 72 hours alone, 100,000 results were returned, and by the project's end, 44 strong treatment candidates had been identified.[3] Encouraged by those results, IBM launched World Community Grid with the goal of creating a permanent technical environment where humanitarian research of this kind could be run continuously.
Through Corporate Social Responsibility, IBM donated its technology and talent to address some of the world's most pressing social and environmental issues. The platform was initially Windows-only and used the proprietary Grid MP client software from United Devices.[4] Demand for broader platform support led to the addition of the open-source BOINC (Berkeley Open Infrastructure for Network Computing) framework in November 2005, bringing Mac OS X and Linux support to the project.[4] By 2007, the Grid MP client had been fully retired and the project consolidated entirely on BOINC.[4]
In September 2021, IBM announced that it had transferred ownership of World Community Grid to the Krembil Research Institute, part of the University Health Network (UHN) in Toronto, Ontario, Canada.[5] Operational management formally transferred to Krembil in February 2022.
Goal
The overarching goal of World Community Grid is to help scientists identify the most important results to study in the laboratory, bringing them one step closer to discoveries that save lives and address global problems. Rather than replacing lab research, WCG acts as a filter: by computationally screening millions — sometimes billions — of candidate molecules or parameter sets, researchers can focus their scarce lab resources on only the most promising leads.
"WCG continues to support open-source and open-data research and helps reduce computational time to allow scientists to address the world's most pressing questions at no cost to the researchers."[5]
All data generated by World Community Grid volunteers must be released into the public domain and made freely available to the scientific community — a foundational requirement for any project accepted onto the platform.[1]
How It Works
World Community Grid runs on top of BOINC, an open-source middleware system developed at the University of California, Berkeley, originally under a National Science Foundation grant.[6] After downloading the WCG client (a pre-configured BOINC installer) from the official website, the software runs quietly in the background. It monitors available system resources and, when the device is idle, downloads a work unit from the WCG servers, performs the required calculations, and sends the results back.
To ensure accuracy, the servers distribute multiple copies of each work unit to different volunteers. When results are returned, they are validated against each other, and statistical outliers are discarded before final data is accepted.[7]
Credits and Points
Volunteer contributions are tracked using the BOINC Credit System. Upon completing a work unit, the BOINC client reports a point value based on software benchmarks (measured in cobblestones, where <math>1\,\text{cobblestone} = \frac{1}{200}\,\text{GigaFLOP-day}</math>). The WCG servers compare claims from each machine that processed the same work unit, discard outliers, and award the averaged value to each contributor.[7] Points allow users to track their personal contribution and compete on leaderboards.
Teams and Partners
Users may join teams created by organizations or individuals, fostering community identity and friendly competition. As of April 2021, World Community Grid had 452 recognized partner organizations promoting the grid within their communities.[7]
CPU Throttling
The BOINC client is designed not to slow down the host computer. World Community Grid sets conservative defaults: the CPU throttle is 60% by default, meaning the client runs at full load for roughly 3 seconds, then pauses for 2 seconds, cycling continuously. This pattern avoids sustained heat buildup. Windows users can additionally install TThrottle, a third-party add-on that reads CPU and GPU temperatures in real time and adjusts computation accordingly.[7]
Methods
Dr. Igor Jurisica's research drives World Community Grid's current scientific direction. Dr. Jurisica is a Senior Scientist at the Krembil Research Institute and a Professor at the University of Toronto, with appointments at Toronto Western Hospital. His work focuses on integrative computational biology — combining large-scale data analysis, machine learning, and network biology to understand complex diseases.
Research within Krembil is focused on the development of diagnostics, treatments and management strategies across three programmatic areas:
- Chronic neurological and neurosurgical disorders — including Parkinson's disease, stroke, epilepsy, spinal cord injuries, dementia, concussion, pain, and depression.
- Ophthalmologic disorders — including glaucoma, macular degeneration, and retinopathy.
- Musculoskeletal system disorders — including osteoarthritis, rheumatoid arthritis, systemic lupus erythematosus, and ankylosing spondylitis.
The primary computational technique used across WCG's biomedical projects is molecular docking, in which candidate drug molecules are algorithmically fitted to target protein structures to predict binding affinity. A typical project may dock tens of millions of compounds against one or more proteins — a task that would require tens of thousands of years of computing time on a single machine, but can be completed in months across the volunteer grid.[8]
Project Team / Sponsors
World Community Grid is currently managed by Dr. Igor Jurisica and his team at the Krembil Research Institute, part of the University Health Network (UHN) in Toronto, Ontario, Canada.[5]
UHN has Canada's largest hospital-based research program, comprising four major teaching hospitals: Toronto Western Hospital, Toronto General Hospital, Princess Margaret Cancer Centre, and Toronto Rehabilitation Institute, as well as The Michener Institute of Education.[9]
Previously, the project was funded and operated by IBM from its launch in November 2004 through February 2022. IBM provided all server infrastructure, administrative overhead, and technical support during that nearly two-decade period. The project is grateful for IBM's extensive financial and operational support.[5]
Research Overview
World Community Grid operates as an umbrella platform hosting multiple research projects simultaneously. Users are enrolled in all active projects by default but may opt out of any they choose.[7] Over the life of the project, WCG volunteers have collectively donated the equivalent of more than 2 million years of computing time and completed more than 6 billion work units.[7]
Active Research
- OpenPandemics - COVID-19 — Launched to enable a rapid-response platform for global disease outbreaks, the project uses molecular docking to screen drug candidates against SARS-CoV-2 proteins in partnership with scientists at Scripps Research. The goal is to identify compounds that could block viral replication, potentially forming the basis of antiviral drugs for COVID-19 and future pandemic pathogens.
- Mapping Cancer Markers — One of WCG's longest-running and most ambitious projects, this research aims to identify robust molecular biomarkers associated with various cancer types. By decoding cancer-rewired biological networks, researchers hope to enable earlier detection and more personalized treatment strategies.
Intermittent Research
- Africa Rainfall Project — Uses regional climate modelling to improve weather forecasts and agricultural planning across sub-Saharan Africa, where rain-fed agriculture supports the food supply for hundreds of millions of people.
- Smash Childhood Cancer — An expansion of earlier WCG work on neuroblastoma, this project searches for the best drug candidates targeting key molecular proteins across a broader range of childhood cancers.
- Help Stop TB — Focuses on finding new drug leads for tuberculosis (TB), which remains one of the world's leading infectious disease killers. The project performs virtual screening of millions of compounds against TB target proteins.
