gcc, SPEC CPU2006, & Sun SPARC Enterprise T5220
Friday Nov 02, 2007
Sun has released benchmarks results on SPEC CPU with GCCfss. GCCfss is a GCC compatible frontend with Sun Studio backend. If you have codes developed with GCC you can now just use it to run really fast on UltraSPARC T2, with all kinds of great optimizations.
For more on GCCfss see: http://cooltools.sunsource.net/gcc/
The Sun SPARC Enterprise T5220 server, running at 1.4 GHz, delivered a result 78.0 SPECint_rate2006 which is slightly lower (1%) when compared with the full Sun Studio 12 compiler.
The Sun SPARC Enterprise T5220 using the GCC for SPARC Systems (gccfss) compiler topped all competitor's single chip results including the 4.7 GHZ POWER6 result from IBM by over 28% which used a proprietary compiler.
The gccfss compiler allows one to use the optimal Sun SPARC optimization tools along with the popular gcc coding conventions and deliver performance that has not been possible before without time consuming code changes.

Benchmark Description
SPEC CPU2006 is made up of two suites of benchmarks, CFP2006 and CINT2006. CFP2006 targets floating-point performance, while CINT2006 targets integer performance.
Each suite has two different measures. First is the CPU measure, which is the performance on the suite as a single stream. This can be either a single thread or automatic compiled parallel run. This measure is further defined by base and optimized runs. Base uses the same compiler flags for all kernels, where optimized is allowed to use different compiler flags for each kernel. Results are compared against a baseline system run that was standardized by SPEC.
The second measure is Rate. It is a measure of how many CPU measures can be run at a time. Typically, it is run as n processes on n processors. It shows how well the same job mix can run on a system under some load. It also is run as a base and optimized set of results.
