Indeed, I was observing the "flash cluster" fiasco at USF years ago (everyone bring your laptop and we will build a supercomputer! ... why? IDK) In any case the only thing that worked was a bunch of pristine identical desktop donated by a vendor. Laptops were notoriously unreliable for any number of reasons.
The most interesting thing I learned was how well some laptops functioned for a "users needs" while technically in a state of "brokenness" There is a larger lesson there. -- Doug > But just think of the challenges of implementing MPI on a network of > ephemerally connected cellphones.
