GCC Compiler Intel Sandy Bridge AVX fpmath
GCC testing for a future article on Phoronix.com. Testing with CFLAGS/CXXFLAGS set to -O3 and -march=native. Benchmarks of GCC 4.7 RC1 when comparing the effects of building the GNU Compiler Collection with the --with-fpmath=avx to see how GCC 4.7 is impacted by the AVX floating-point arithmetic.

CLOMP
CLOMP is the C version of the Livermore OpenMP benchmark developed to measure OpenMP overheads and other performance impacts due to threading in order to influence future system designs. This particular test profile configuration is currently set to look at the OpenMP static schedule speed-up across all available CPU cores using the recommended test configuration. Learn more via the OpenBenchmarking.org test page.
NAS Parallel Benchmarks
C-Ray
This is a test of C-Ray, a simple raytracer designed to test the floating-point CPU performance. This test is multi-threaded (16 threads per core), will shoot 8 rays per pixel for anti-aliasing, and will generate a 1600 x 1200 image. Learn more via the OpenBenchmarking.org test page.
Smallpt
Smallpt is a C++ global illumination renderer written in less than 100 lines of code. Global illumination is done via unbiased Monte Carlo path tracing and there is multi-threading support via the OpenMP library. Learn more via the OpenBenchmarking.org test page.
