DENIS@home is a volunteer distributed computing project based on the BOINC middleware platform. The project is operated by the CoMBA (Computational Multiscale Biology and Medicine) research group at Universidad San Jorge in Zaragoza, Spain, and focuses on large-scale simulations of cardiac electrophysiology and cardiovascular disease research.[1][2]
The project's name is an acronym representing its five main principles: Distributed computing, Electrophysiological models, Networking collaboration, In silico research, and Sharing knowledge.[3]

History
DENIS@home was launched in 2016 as a research initiative to use volunteer computing for the simulation of cardiac electrophysiological models.[4] The project was developed by researchers from the CoMBA group to provide computational resources for large-scale studies into cardiac arrhythmias, ventricular cell behavior, and the effects of drugs on the human heart.[5]
The project was listed among BOINC-based scientific computing initiatives by the University of California, Berkeley and has been referenced in volunteer computing communities and distributed computing forums.[6]
Why DENIS@home?
More than 17 million people die each year from cardiovascular diseases, representing approximately 31% of all global deaths.[7] DENIS@home was created to provide researchers with the computational power required to investigate the electrical activity of the heart and develop improved cardiac electrophysiological models.
The platform allows volunteers to donate unused CPU processing time from their personal computers to scientific simulations.[8]
Goal
The five pillars of DENIS@home are:
- Distributed computing
- Electrophysiological models
- Networking collaboration
- In silico research
- Sharing knowledge
Distributed computing
DENIS@home uses volunteer computers to perform large numbers of cardiac electrophysiological simulations. The project uses the idle processing capacity of Windows, Linux, and macOS computers connected through the BOINC middleware platform.[9]
The distributed nature of BOINC enables researchers to process large simulation batches that would otherwise require access to expensive supercomputing infrastructure.[10]
Electrophysiological models
DENIS@home computes large sets of cardiac electrophysiological model variations. These models mathematically represent the electrical behavior of cardiac cells and are used to study arrhythmias, heart failure, and drug interactions.[11]
The models are described using the CellML language, an XML-based open standard developed by the Auckland Bioengineering Institute for storing and exchanging mathematical biological models.[12]

Networking collaboration
The project was designed to connect volunteers and researchers internationally through a collaborative computing infrastructure. DENIS@home also encourages scientific collaboration between institutions and research groups working in computational cardiology.[13]
In silico research
The project focuses on in silico cardiac simulations, allowing researchers to investigate heart behavior under normal and pathological conditions using computer models rather than laboratory or clinical experimentation alone.[14]
Sharing knowledge
DENIS@home promotes open scientific research. Results produced using the project are expected to be published openly, and the software developed for the project is released under the Apache License 2.0.[15]
Methods
Volunteers may choose to run one or more scientific applications through the BOINC client:
- Beta of DENIS-myocyte (DENIS_Myocyte_Beta): Testing application used to validate modifications to the simulation software.
- New human ventricular cell model (NHuVe): Development of updated ventricular cell electrophysiological models.
- Human ventricular cell models optimization (HuVeMOp): Optimization of commonly used ventricular cell models for electrophysiological marker representation.
Electrophysiological models are used to investigate the electrical activity of cardiac cells and predict the effects of pharmaceutical compounds and pathological conditions on the heart.[16]
All DENIS@home software is distributed under the Apache License 2.0 and source code has been published through the project's Bitbucket repositories.[17]

Computing platform
DENIS@home applications are available for:
- Microsoft Windows
- Linux
- macOS
The project primarily uses CPU-based computations and supports both 32-bit and 64-bit systems depending on application version.[18]
Project team / Sponsors
The members of the research group participating in the project include:
- Jesús Carro
- Violeta Monasterio
- Alejandro Alcaine
- Marta Gómez
DENIS@home is developed and maintained by the CoMBA research group at Universidad San Jorge.[19]
Scientific results
The project publishes scientific results and associated research papers through its official publications page.[20]
