How Linux Performance Changed In 2017 With Clear Linux & Ubuntu

First up are a few of the OpenMP scientific benchmarks.

Ubuntu saw a significant improvement in performance for this benchmark when moving from 16.10 Yakkety Yak to the current Ubuntu 18.04 LTS daily snapshot. While Clear Linux didn't see any change in performance for this fluid dynamics simulation over the course of 2017, its performance remains superior to where Ubuntu 18.04 LTS is currently performing.

Parboil's CUTCP explicit-water biomolecular model simulator also saw performance improve greatly from Ubuntu 16.10 to 18.04 daily, but that current state of Ubuntu only matches where Clear Linux was at when ending out 2016. With the latest Clear Linux release, the Intel-optimized Linux distribution has managed to squeeze even greater performance out of this OpenMP benchmark. Keep in mind both distributions right now were tested with GCC 7 and Linux 4.14.

With Parboil's Stencil 3D grid benchmark, the Ubuntu performance improvement over 2017 was enough to position it slightly ahead of Clear Linux that saw no change in performance this year for this particular workload.

When switching over to Rodinia for additional scientific workloads, Clear Linux saw a huge boost in performance with the LavaMD test running twice as fast now as it did last year while Ubuntu's performance remained the same.

In two other Rodinia scientific tests, the performance improved in 2017 likely due to the GCC 7 compiler upgrade and where now both Clear Linux and Ubuntu were running about the same speed.
