SGI Altix benchmarking whitepaper

I'm sure that many of you also got the marketing email today entitled "SGI Altix outperforms AMD Dual-core Opteron
Systems".

Have not read the paper yet, just passing along the actual URL to the paper ...

Skipping the intro and setup pages, the actual PDF is here:

Excerpt:

Standard benchmark test cases from the following chemistry
applications were used:
• Gaussian 03 rev C.02 (Gaussian)
• DMol3 from Accelrys® Materials Studio® (Accelrys)
• CASTEP from Accelrys Materials Studio (Accelrys)
• VASP (University of Vienna),
• NAMD (University of Illinois at Urbana Champagne),
• Sander (Amber), and
• PMEMD (Amber)


Results of the tests revealed that the SGI Altix 330 using shared
memory and unmatched I/O throughput achieved superior
performance and ran faster than twice the number of cores in
comparable AMD dual core Opteron-based systems.
In addition, a Parallel Throughput System test revealed that the
SGI Altix 330 built on SGI NUMAflex™ architecture experienced
only 1% degradation in performance when running Gaussian
test397 on a fully loaded system (24.4 minutes on a fully loaded
system compared to 24.1 minutes in a stand alone test) as compared
to a 33% degradation in performance for the comparable
AMD dual core Opteron-based system (71 minutes on a fully
loaded system compared to 53 minutes in a stand alone test).



Regards,
Chris
