cpufp

This is a cpu tool for testing the floating-points peak performance. Now it supports linux and x86-64 platform. It can automatically recognize the x86 instruction sets and select the proper set to do test.

build: sh build.sh

test: ./cpufp num_cores

clean: sh clean.sh

Example on Intel i7 4790K(Haswell, 4 cores, 8 threads, fixed at 4GHz): $ ./cpufp 1 Core used: 1 FP32 perf: 127.8892 GFLOPS. FP64 perf: 63.9466 GFLOPS. $ ./cpufp 2 Core used: 2 FP32 perf: 255.7734 GFLOPS. FP64 perf: 127.8866 GFLOPS. $ ./cpufp 4 Core used: 4 FP32 perf: 511.5616 GFLOPS. FP64 perf: 255.7780 GFLOPS. $ ./cpufp 8 Core used: 8 FP32 perf: 511.5075 GFLOPS. FP64 perf: 255.7590 GFLOPS.

The next version may support ARMv7 and ARMv8 architectures. Welcome for bug reporting.
