Nvidia and ARM: It's a parallel, parallel, parallel world

Where's the challenge?

I have a feeling that with increasing parallelism and diversity of architecture, it may be impossible for a programmer to write the optimal parallelization into the code. It may be more of a challenge for the development environment or compiler designers to best utilize the architecture's capabilities.

LOHAN ideas..

Balloon burst detection false-positive issue due to atmospheric instability

Hola!

A design issue to consider:

If I understand correctly, there's an accelerometer on board that is supposed to detect balloon burst - I guess by detecting a switch to zero-g. actually, detecting loss of lift.

In case this detection is used to fire the rocket motor, then careful false-positive prevention is in place - we don't want anyone firing off prematurely..

I can imagine false balloon burst detection due to atmospheric instability, running into a cloud for example, which could play havoc on acceleration signals.

Being unfamiliar with the accelerometer and computing power on disposal, this is as far as I can go.
