Using GCC 4.7.0 on an AMD FX-8150 Bulldozer eight-core CPU from an ASUS motherboard running a near final Ubuntu 12.04 LTS x86_64 with the Linux 3.2 kernel. Testing of vanilla GCC 4.7..0 and running some open-source computational tests when using CFLAGS/CXXFLAGS of -O3 and then varying -march= flags. The march= GCC 4.7 options tested for the AMD Bulldozer FX-8150 were k8, k8-sse3, barcelona, btver1, and bdver1 (optimal). Testing for a future article on Phoronix.com by Michael Larabel.

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.
The Himeno benchmark is a linear solver of pressure Poisson using a point-Jacobi method. Learn more via the OpenBenchmarking.org test page.
