Hello,
here it is a challenge to you patience explaining thing to a newbie (me)

. To build a cluster, can I use only Parallella servers boards (the cheapest)?
If so, how do I set them up without plugging a screen/keyboard? Is that what MPI or PVM are used for? can I use a regular PC to control them? I'm starting to explore this posibility as an alternative to rent cluster time on the cloud or at other universities.
Thank you
Ale
