Sun Studio Trounces Intel Compiler on Intel Chip
By Jhenning-Oracle on Apr 13, 2009
Today Sun announces a new world record for SPECfp2006: 50.4 on a 2-chip Nehalem (Intel Xeon X5570) Sun Blade X6270.
Congratulations to my colleagues in the Sun Studio Compiler group - the fun thing about this result is that it beats Intel's own compiler on this Intel chip by 20%, due to the optimization technologies found in the Sun Studio 12 Update 1 compiler.

|Hitachi BladeSymphony BS2000||Xeon 5570||2.93||2||8||42.0||39.3||Top result at www.spec.org as of 14 Apr 2009|
|IBM Power 595||POWER6||5.00||1||1||24.9||20.1||Best POWER6 as of 14 Apr 2009|
Note that even with the less aggressive "Base" tuning [SPECfp_base2006] the Sun Blade X6270 beats the best-posted "Peak" tuning from competitors [SPECfp2006].
Of course, the Intel compiler engineers are bright folks too, and they will no doubtless quickly provide additional performance on Nehalem. Still, it's fun to see the multi-target Sun Studio optimization technology deliver top results on a variety of platforms, now including Nehalem.
As to integer performance - the Sun Blade also takes top honors there [for peak]:

|Fujitsu Celsius R570||Xeon 5570||2.93||2||8||36.3||32.2||Top SPECint2006 result as of 14 Apr 2009|
The Sun Blade results have been submitted to SPEC for review, and should appear at SPEC's website in about 2 weeks.
On a personal note, this was my first time using OpenSolaris. The level of compatibility with other operating systems is substantially improved; and utilities that this tester likes having handy are built in (e.g. the NUMA Observability Tools); and ZFS zips right along, needing less attention than ufs and delivering better performance.
