MalariaControl.net

MalariaControl.net was the first volunteer-computing project ever to model the dynamics of a human disease at population scale. Operated by the Swiss Tropical and Public Health Institute (Swiss TPH) in Basel, in partnership with University of Geneva computing infrastructure and the Africa@home network, it ran from May 2005 until June 2016 — making it one of the longest-lived medical volunteer-computing projects in history.

The science was epidemiological simulation. Each work unit instantiated a virtual population of 50,000 to 100,000 people, simulated the seasonal transmission of Plasmodium falciparum through that population over many years, and modeled the impact of various intervention scenarios — bed nets, indoor residual spraying, mass drug administration, vaccine rollouts, drug-resistance evolution. Each work unit took roughly an hour of CPU time on a typical home computer; aggregated over thousands of volunteers, the project ran tens of thousands of intervention scenarios that no national health ministry could have run on its own infrastructure.

The legacy outlives the BOINC project. Starting November 2010, with funding from the Bill & Melinda Gates Foundation, MalariaControl.net's underlying simulation code was released as OpenMalaria, an open-source framework that public-health agencies and academic groups still use today to plan country-level intervention strategies. Over the project's ten years it produced 30 peer-reviewed journal articles, with active-volunteer counts peaking around 10,000 (about 37,000 cumulative registrations).

The BOINC project was terminated on 21 June 2016, with Swiss TPH explaining that their cluster computing capacity had grown enough that volunteer cycles were no longer the bottleneck. As a piece of public-health history, MalariaControl.net demonstrated that volunteer computing could attack a global infectious disease at population scale — and helped establish the modeling toolkit that informs WHO-coordinated malaria-elimination work to this day.
