Cluster kids, pick your weapons: It's the Battle of Leipzig 2.0

Thumb Up

as a former alumnus of EPCC

GO TEAM EPCC!

Hopefully, as the author stated rightly, this would encourage other UK Universities with expertise in HPC to join in the challenge such as Imperial, Bristol, Cambridge and Southampton to name a few.

ISC'13

I'll be there in Leipzig this summer. It's going to be tough to beat the Chinese teams even though I am rooting for EPCC (University of Edinburgh).

I wasn't really aware that you are allowed to also hand tune the codes yourself as it is not clearly specified in the regulations of the HPC Advisory Council. If that's the case, then this competition is actually more exciting than I previously thought.

Met Office wants better supercomputer to predict EXTREME weather

Met HPC

I am studying the MSc. in HPC @ Edinburgh Univ. and distinctively remember a lecture on Exascale computing held by a Professor heavily involved in the HPC area within the UK and EU regarding the need for more and more computing power especially for weather forecasting. This is because as some have already described above, in order to have better medium and long term predictions, you need to compute bigger and bigger areas. With a normal distributed system, if you decompose millions of these sub areas across machines scattered around the world, the intensive halo swapping (neighbourhood borders) communications would absolutely grind the entire computation to a halt. This is why you need more cores and faster interconnects for being able to throw a bigger problem at the beast (Gustafson's Law) which in turn should hopefully mean a more accurate prediction in a faster manner.

I wouldn't necessarily blame their models to be wrong, just their capabilities on how much data they can actually use them on which for this particular science seems to be a rather important point to take into account.

hail to the great analysts

Was one of the analysts you've spoken to Florian Mueller by any chance? Surely a very unbiased source that you guys seem to rely upon quite frequently.

Nokia lobs more patent claims at Apple

ich
WTF?

I might be gullible..

But having looked at some of the patent portofolio that Nokia holds, I keep wondering how the heck Apple managed to escape in round 1. Oh wait, it was a US federal court.

Come on, everyone else seems to be paying the finns their deserved royalties but Apple.

Never argue with idiots. They'll just bring you down to their level and beat you with experience.

poor signal, dropped calls...

The IPhone 4 is so REVOLUTIONARY it shouldn't be used as a phone...
