Reported 07/21/09

Significance of Results

Results are presented for the SPEC CPU2006 rate benchmarks run on the new 1.6 GHz Sun UltraSPARC T2 and Sun UltraSPARC T2 Plus processors based systems. The new processors were tested in the Sun CMT family of systems, including the Sun SPARC Enterprise T5120, T5220, T5240, T5440 servers and the Sun Blade T6320 server module.

Benchmark Description

SPEC CPU2006 is SPEC's most popular benchmark, with over 7000 results published in the three years since it was introduced. It measures:

  • "Speed" - single copy performance of chip, memory, compiler
  • "Rate" - multiple copy (throughput)

The rate metrics are used for the throughput-oriented systems described on this page. These metrics include:

  • SPECint_rate2006: throughput for 12 integer benchmarks derived from real applications such as perl, gcc, XML processing, and pathfinding
  • SPECfp_rate2006: throughput for 17 floating point benchmarks derived from real applications, including chemistry, physics, genetics, and weather.

There are "base" variants of both the above metrics that require more conservative compilation, such as using the same flags for all benchmarks.

See here for additional information.

Key Points and Best Practices

Result on this page for the Sun SPARC Enterprise T5120 server were measured on a Sun SPARC Enterprise T5220. The Sun SPARC Enterprise T5120 and Sun SPARC Enterprise T5220 are electronically equivalent. A SPARC Enterprise 5120 can hold up to 4 disks, and a T5220 can hold up to 8. This system was tested with 4 disks; therefore, results on this page apply to both the T5120 and the T5220.

Know when you need throughput vs. speed. The Sun CMT systems described on this page provide massive throughput, as demonstrated by the fact that up to 255 jobs are run on the 4-chip system, 127 on 2-chip, and 63 on 1-chip. Some of the competitive chips do have a speed advantage - e.g. Nehalem and Istanbul - but none of the competitive results undertake to run the large number of jobs tested on Sun's CMT systems.

Use the latest compiler. The Sun Studio group is always working to improve the compiler. Sun Studio 12, and Sun Studio 12 Update 1, which are used in these submissions, provide updated code generation for a wide variety of SPARC and x86 implementations.

I/O still counts. Even in a CPU-intensive workload, some I/O remains. This point is explored in some detail at http://blogs.sun.com/jhenning/entry/losing_my_fear_of_zfs.

Comments:

Having lost your fear of ZFS some two-odd months back is that reflected in the filesystem used in each of these new Sun results?

Also, drifting away from the results themselves since they are all rates, doesn't the emergence of auto parallelization mean this description:

'"Speed" - single thread performance of chip, memory, compiler'

needs an update?

Posted by rick jones on July 22, 2009 at 01:30 AM PDT #

Hello Rick, yes, the 255-thread version benefits from ZFS. Thanks for the edit about the definition of speed - I am fixing it to say "single-copy", not "single-thread". Good point. -john
