Intel Ivy Bridge GCC 4.7 LTO
Quick benchmarking of GCC 4.7.1 with the Link-Time Optimization (LTO) support. Building the test profiles with CFLAGS/CXXFLAGS that includes -flto for link-time optimizing and then without. Benchmarking by Michael Larabel for a future article looking briefly at the GCC Link-Time Optimization support for some C/C++ programs.

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

Timed PHP Compilation
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.
