What's new?


Many smartphones are a supercomputer! Samsung's Power Sleep App has been launched by Feb 14. This Android app is not only an alarm clock, but also supports SIMAP. During the night, when connected to WiFi and after fully loading the battery, the CPU of the smartphone or tablet crunches SIMAP work packages.

The scientific computing part of Power Sleep is just the BOINC client. The Power Sleep App has been developed by Samsung Austria and PocketScience in collaboration with the SIMAP team. It makes donating CPU time very simple for people who didn't know about BOINC before. Samsung has launched a media campaign about Power Sleep in Austria. The app, however, can be downloaded from all over the world. We hope this initiative will become a big success and will help to widely establish volunteer computing with BOINC on mobile devices.

What is SIMAP?

Protein structure

Proteins are the main functional units of all living organisms. If we want to understand human life, aging and disease, we need to study proteins. If we want to harvest compounds and energy from microorganisms, we need to study proteins. If we want to relate global biogeochemical cycles to changing climate conditions, we ... yes - need to study proteins. However, this is no simple task. Many million protein sequences (the arrangement of their building-blocks) have been characterized so far. Many thousand new ones are discovered every day. The similarities among all these protein sequences are crucial for protein research. They help us studying the structure and function of proteins, and their biological roles. SIMAP facilitates protein research by providing pre-calculated protein similarities and protein domains. Read more...

What do you do in BOINCSIMAP?

protein alignment

SIMAP contains about all currently published protein sequences and is continuously updated. In BOINCSIMAP, we calculate the similarities of newly imported proteins. Thereby we keep the SIMAP database up-to-date. Protein similarities are computed using the FASTA algorithm which provides optimal speed and higher sensitivity compared to the popular BLAST.

Why do it?

Eukaryotic cell

The SIMAP database is an important bioinformatic resource that is used by scientists from all over the world. All data from SIMAP are freely available. Individual researchers use the SIMAP database via the public Web portal, e.g. to investigate the evolution and function of individual proteins. Furthermore, many bioinformatics projects access SIMAP directly via the public Webservice or large-scale download facilities. Your support for BOINCSIMAP keeps the SIMAP database running.

How do it?


BOINC lets you contribute unused computing power of your computer or mobile device to research projects. You may contribute to a single project (like BOINCSIMAP), or to any combination of them. It's easy to participate in a BOINC project: download and install BOINC. You will be asked to select a project and enter your email address and a password. That's it! Read more...

I\'m a software developer that cares about health and science issues, so participating in these grid projects is a natural fit. I did Seti some years ago, left it, and didn\'t come back. A new puter got me thinking how Seti could probably use it, and I discovered all this BOINC stuff. Awesome! I now...
