Usecases/experience of JavaScript for HPC (High Performance Computing)

Question

Microsoft has announced preview version of Hadoop on Azure. JavaScript can also be used to write MapReduce jobs on Hadoop.

I know that there had been a lot of work on JavaScript in the browsers for the last few years to improve the performance (especially V8). Can anyone share use-cases or their experience using JavaScript for HPC (High Performance Computing)?

Here is an intersting article on using JavaScript on Hadoop with Rhino.

Answer 1

I don't know much about Rhino to be honest, but I do know some stuff about Node.js (which is based on V8), and one of the most important is that it's not recommended for heavy cpu usage apps.

The best thing would be to write C++ addons for stuff that you know will take an important amount of CPU.

Another useful link that you should read is about Fabric and (for ex.) what it does to improve a basic fibonacci server to perform better: http://fabric-engine.com/2011/11/benchmark-node-js-fibonacci-server/
