Traffic jam shockwaves are pretty cool.

So I can only deduce that the predictive and flock systems that are being developed for computer driven vehicles, will also be used in HPC in a not so far future! Or vice-versa even!! Uhm... I guess hierarchical management agents might get to be introduced, instead of a single master in the cluster... thus relieving the interconnects with alternating data transfers... Nonetheless, one thing that can help in situations of cores being faster than the interconnects, is to use "real-time" data compression... I hope this is an hypothesis that can be taken into account!! Since you've got CPU to spend... think compact! It's not the ideal solution, but saves a bundle in money while you can't get the new "hyper-speed" network, and the current one was just a "bad buy". But hey, what do I know, I'm just a newbie in HPC! So basically, this means that the “traffic jam shockwave” (youtube it) also happens in HPC… even if the acceleration is digital!
