+10 (on the caring about things other than DP, and even SP).

There's a fairly large cross section of people whose simulation, codes, 
etc. have to deal with other-than-*P performance issues. Instruction 
graduation rate, IO and network bandwidth ... all of these things matter 
for a large and growing segment of the HPC community.  I've argued many 
times that basing the "fastest supercomputer" metric off a parallel LU 
decomposition manages to miss an ever larger segment of the HPC 
community, for whom that metric is not useful.
