About DENIS@Home

http://denis.usj.es/

The Project

DENIS uses volunteer hosts to compute large packets of cardiac electrophysiology simulations.
You can participate by downloading and running a free program on your computer. Click HERE to learn how to collaborate. By using the idle time of your computer, you’d be helping researchers on their research projects which require vast amounts of computing power.

Electrophysiological models are a powerful tool to study the electrical activity of cells under normal or pathological conditions. These models can also help predict the effects of drugs in heart and brain cells. These models are complex and it’s neccessary to simulate them many times (varying the conditions or model parameters). For this reason, researchers in this field usually require high computational power. We have created DENIS as a simulation infrastructure to help researchers. You can read more about research in DENIS in the section Science.

The five pillars of DENIS are:

Distributed Computing
Electrophysiological Models
Networking Collaboration
In Silico Research
Sharing Knowledge

DENIS is being developed by an small team of researchers based at San Jorge University in Zaragoza, Spain. You can find more information in the section About us.

BECOME A VOLUNTEER
To be a volunteer Download and run the BOINC client. Choose Add Project and select DENIS@home.

What is DENIS?

Distributed computing.
Electrophysiological models.
Networking collaboration.
In silico research.
Sharing knowledge.
Distributed computing

DENIS uses volunteer devices to compute large amounts of cardiac electrophysiological simulations. DENIS uses the idle time on your computer (Windows or Linux) to simulate the electrical activity of the heart.

DENIS works over the Berkeley Open Infrastructure for Network Computing (BOINC). BOINC is an open source middleware system developed at the University of Berkeley.

To become a volunteer see how to Collaborate.
Electrophysiological models

DENIS has been created to help researchers to compute very large groups of cardiac electrophysiological model variations.

Cardiac electrophysiological models are mathematical representations of the electrical activity of the cardiac cells.

Models used in DENIS are described using the CellML language to facilitate other researchers to include their models in DENIS.

CellML is an open standard based on the XML markup language. CellML is being developed by the Auckland Bioengineering Institute at the University of Auckland and afiliated research groups. More information in the CellML Web Page.
Networking collaboration

DENIS connects volunteers with researchers to help them in their projects. No matter where you are. No matter where the project is. We want to connect you.

We don't only want to connect resarchers and volunteers. We also want to connect researchers and help them to collaborate. We are currently working on it. Stay tuned, we will keep you informed.
In silico research

We could have asked you to use your heart, but we believe it is easier for you to give as your computer for a while.

In Silico simulations of the electrical activity of the heart have become an indispensable technique to increase our knowledge of the heart behaviour under normal or pathological conditions.

DENIS wants to be a powerful tool for those all that make research in cardiology.
Sharing knowledge

DENIS works because the volunteers share their computational capacity with us. For this reason, all the researchers that use DENIS must share their results with all the people.

All the result must be published and all the publications derived of the use of DENIS have to be freely available. All the models used in DENIS must be shared once the project has end.

Project up and running well with a very low error rate . ( I have 1809 valid / 12 error )
Reports on WUProp, BOINCstats and FreeDC.
Forum etc. all enabled.
Units currently run for 15 - 20 mins each and give 9 - 10 credits each.
Currently task limit of 3 tasks per usable core per download request so no chance of all the units being hogged by a few people and so far server has work available most of the time.
TSBT currently #25 in the world and #1 in UK.

Seems a good worthwhile project to run.

Sounds interesting, and also a candidate for my wuprop advancement :)

Sorry...I hate posting something irrelevant , but the project name just reminds me a Blondie song (warning...old school :D)...

There was two things that came to my mind when I saw the project title.
The 1st was the same as Scole - Blondie
The 2nd is the following (I know the spelling isn't the same though)

Funny, I thought of a red and black stripy shirt too :D Time to terrorise some ' softeys ' :twisted:

Is this project called after someone called Denis?
It sounds so cool, like imagine a whole project called after your name!!

Unfortunately it's named for
Distributed computing.
Electrophysiological models.
Networking collaboration.
In silico research.
Sharing knowledge.

I agree, it would be cool. :D

Note that the nice optimized apps from Cruncher and Sosef have been set aside for the next phase (see your BOINC manager about unrecognised apps).
