September 10, 2007 ... IBM® today announced results for the IBM System x™ 3455 running the
LS-DYNA benchmark with the 3cars (3 vehicle collision) workload.
The x3455 server achieved an elapsed time of 31,526 seconds, which is better than the 32,578
seconds of elapsed time achieved by a single-node 8-core blade system using the Quad-Core
Intel® Xeon® X5355 processor at 2.66GHz. (1) Improved LS-DYNA performance can result in
quicker simulations by industry users, which in turn can result in delivery of better and safer
products to the marketplace in less time.
These are the first LS-DYNA benchmark results published for the x3455 using the AMD
Opteron™ Model 2347 quad-core processor. For this benchmark, the single-node x3455 system
was configured with the AMD Opteron Model 2347 quad-core processor (1.9GHz, 512KB L2
cache per core) and eight 2GB PC2-5300 ECC DDR2 memory. (2)
The 2-socket x3455 is an ultrathin 1U rack-optimized server designed for high performance at an
affordable price. The x3455 server features AMD Opteron™ quad-core processors and IBM’s
Xcelerated Memory Technology™, which enables faster access to data, and helps provide
outstanding performance for large memory configurations with the ability to support 667MHz
memory access speed of fully populated memory. The x3455 supports up to 48GB of PC2-5300
667MHz ECC DDR2 memory with IBM Chipkill technology for high performance and reliability. In
addition, the AMD Opteron quad-core processors used by the x3455 incorporate AMD’s dual
dynamic power management technology designed to increase performance per watt while
reducing power consumption.
About the LS-DYNA benchmarks
LS-DYNA, developed by the Livermore Software Technology Corporation, is a general-purpose
transient dynamic finite element program capable of simulating complex real world problems. It is
optimized for shared and distributed memory Unix®, Linux®, and Microsoft® Windows®
platforms. LS-DYNA is being used by automobile, aerospace, manufacturing and bioengineering
companies. LS-DYNA is heavily used in automobile crash simulation.
