A platform for World Wide ComputingQMachine (QM) is a web service that can incorporate ordinary web browsers into a World Wide Computer without installing anything.
This app for the Chrome Web Store enables users to exceed the paltry 5MB quota that their browsers allot for IndexedDB and/or WebSQL. QM does not require that this app be installed in order to function correctly, but if your workflow uses either of those in-browser databases, you may find the app to be very useful. Otherwise, this app's main use is to provide a clickable bookmark. Future versions may re-enable QM's offline execution mode.
"QMachine: Commodity Supercomputing in Web Browsers" has now been published online in BMC Bioinformatics. This "Highly Accessed" report explains some of the design decisions behind QM, demonstrates the use of QM in scientific workflows, and elaborates on some of the future directions. The accompanying screencasts, one of which was featured by the HPCwire and insideHPC news sites, are available on YouTube. QM has also graced the front page of Hacker News.
