12:14 <Romulus> Bugger all, I dunno, siamba.

12:14 <siamba> desti: have you already ordered haswell cpu/mobo?

12:14 <siamba> sorry, Romulus

19:45 <desti> http://www.computerworld.com/s/article/9239710/China_surpassing_U.S._with_54.9_petaflop_supercomputer

19:45 <Romulus> <http://tinyurl.com/kf5aqe6> (at www.computerworld.com)

19:46 <PovAddict> eh, BOINC is estimated at 7000 petaflops

19:49 <desti> hmm

19:51 <PovAddict> flops can't be measured properly anymore

19:51 <PovAddict> with CPU pipelining, the same floating-point operations in a different order may take a different amount of time

19:51 <PovAddict> with CPU caches, access to memory may be very expensive or it may be not, if you access recently-accessed memory again

19:52 <PovAddict> and for some supercomputer workloads, the speed of communication between nodes may end up being more important than the processor speed
