Benchmarks - Sciencemark 2

Sciencemark 2

Science Mark 2.0 is an attempt to put the truth behind benchmarking. In an attempt to model real world demands and performance, SM2 is a suite of high-performance benchmarks that realistically stress system performance without architectural bias.

"MemBench" - An unbiased, synthetic benchmark that sweeps through more than 15 different, publicly available, memory copy algorithms to measure the peak memory performance of your CPU’s caches and your memory subsystem.

"BlasBench" - Scientists and engineers use large matrix multiplication to determine peak MFLOPS. BlasBench measures the MFLOPS of your machine via large matrix multiplication. The benchmark can be run in single or double precision. Real world matrices are often large and don't fit into the processor's cache. Science Mark 2’s optimized implementations of matrix multiplication in single and double precision, from an algorithm point of view, perform remarkably better than the blind man's matrix multiplication routine. BlasBench uses building blocks called kernels at its lowest level that determine overall MFLOPS performance. These kernels are written in C and a wide assortment of assembly forms (SSE Vector, SSE2 Vector, SSE2 Scalar, x87, 3DNow! Vector) to support any processor architecture in the x86 market.

"MolDyn" - Science Mark 2.0 performs Molecular Dynamics Simulations. It has the flexibility of simulating any 5 noble gases, in 3 different crystallographic configurations, with variable numbers of atoms at a user specified temperature.

"Primordia" - Science Mark 2.0 computes the electronic orbitals for the atoms between Hydrogen and Promethium in the periodic table using a Restricted Hartree-Fock method. Primordia outputs the total all electron energy of the atom in addition to the kinetic and potential contributions. The user is allowed to specify different grids upon which the orbitals are determined.

"QMC" - The Primordia orbitals are utilized to simulate and determine the properties of molecules using the extremely accurate quantum Monte Carlo algorithm. Primordia and QMC are indicative of what is done in commercial chemistry codes on workstations and supercomputers about the world.

"FEM" - The behavior and properties of fluids and structures is modeled using the Finite Element Method. Similar tasks are performed by automotive, aerodynamic and civil engineering companies during their product design.

"Cipher" - Benchmark tests four different forms of encryption algorithms, AES 128/256 bit and RSA 512/1024 bit. Sean's AES 128 bit encryption algorithm is quite possibly the fastest implementation on the face of the earth.

From the scores, we can see the good of Dual Core especially in Molecular Dynamics, Primordia and BLAS/FLOP tests. The scores obtained are again very close to the ones obtained on Gigabyte board.

From the chart above, it is not difficult to see that the first 2 tests works better in a multiprocessing environment. As 820D couldn't work in Dual core mode on this chipset, we see a dip in result in molecular dynamics and primordia tests. The Stream test failed but the last two tests are comparable with the rest of the boards compared.
