Modifying software to run on Parallella?

[Alan]

Hey I'm wondering would it be possible to be able to simply add a few lines of code (maybe something that refers to another program but can be applied to any program) to existing open source software to make it run on a parallella? Or would you have to rewrite the entire code to work effectively due to threading issues and such?

That pretty much depends on the nature of the software you want to port, doesn't it? If you take a single thread software which uses standard C, for example, w/ some common libraries, then it is easy to just compile it, load and run on an eCore (or run multiple copies in parallel on a few cores). However, in taking such program and *parallellizing* it would take more effort from your side - but this is really not particular to the Parallella platform. The eSDK provides some basic API to help you perform the communications between eCores. The implementation of the parallel algorithm is up to you.
