This is a cpu tool for benchmarking the floating-points peak performance. Now it supports linux and x86-64 platform. It can automatically sense the local SIMD ISAs while compiling.

build:

./build.sh

benchmark:

./cpufp --thread_pool=[xxx]

clean:

./clean.sh

xxx indicates that all the cores defined by xxx will be used for benchmarking(by affinity setting). For example, [0,3,5-8,13-15].

For single Golden Cove(big) core:

$ ./cpufp --thread_pool=[0]
