Dual Chip World Record, SPEC OMP2001: Sun SPARC Enterprise T5240

Thursday Apr 10, 2008

The Sun SPARC Enterprise T5240 server delivers the best performance on the SPEC OMPM2001 benchmark for two chips. These results were run on the Sun SPARC Enterprise T5240 server using the UltraSPARC T2 Plus processor running at 1.4 GHz.

The Sun SPARC Enterprise T5240 server running the UltraSPARC T2 Plus processor at 1.4 GHz, beat all dual chip scores running SPECompM2001 with a score of 25488.

The Sun SPARC Enterprise T5240 server running the UltraSPARC T2 Plus processor at 1.4 GHz, beat all dual chip scores running SPECompM_base2001 with a score of 21145.

The Sun SPARC Enterprise T5240 server running at 1.4 GHz beat the best IBM dual chip result (POWER6) by 25% on the SPECompM2001 benchmark.

Benchmark Description

The SPEC OMPM2001 Benchmark Suite was released in June 2001 and tests HPC performance using OpenMP for parallelism.

  • 11 programs (3 in C and 8 in Fortran) parallelized using OpenMP API
Goals of suite:
  • Targeted to mid-range (4-32 processor) parallel systems
  • Run rules, tools and reporting similar to SPEC CPU2000
  • Programs representative of HPC and Scientific Applications

How does a new IBM Power6 at 5Ghz compare?

Posted by Kevin Hutchinson on April 10, 2008 at 10:29 AM PDT #

My Opinion, UltraSPARC T2 really make 4.7GHz IBM p570 4-core (4RU box) and almost 10x more expensive and less performance on web, appl, & database applications. The 2-chip UltraSPARC T2 Plus (1RU and 2RU) now make 4.7GHz IBM p570 8-core (8RU box) look slow and very expensive. IBM now avoids many benchmarks on the p570 to avoid comparisons. They even avoid the STREAM benchmark to show delivered bandwidth!

As far as I know the POWER6 5GHz is only on the larger systems that cost 100x more for the largest. Is the Power6 shipping yet?
