TOP500 Systems and Exascalar Efficiency, Part II

Over at Datacenter Knowledge, Intel’s Winston Saunders with Part II of his feature piece on how the most recent Top500 and Green500 machines stack up in terms of Exascalar, the “logarithmic distance” to 1018 flops in a 20 MegaWatt power envelope.

The “big” observation is that the range of system efficiency for the Top 10 systems is strongly biased toward the upper end of the distribution. The performance distribution for the top 10 spans a greater range and is “flatter.” Looking at the whole top500 Population there appears a deeper systematic difference between the distribution of performance and efficiency data. (If there’s interest – just request it in the comments section below – I can blog about it.)
