This is a cpu tool for benchmarking the peak performance of floating-points and AI ISAs.
It can automatically sense the local SIMD|DSA ISAs while compiling.

./cpufp --thread_pool=[xxx] --idle_time=yyy
--thread_pool: [xxx] is the list of cpu thread to benchmarking, from setting affinities. Please reference the result of lstopo command. For example, [0,3,5-8,13-15].
--idle_time: the interval time(sec) between any two adjacent benchmarks, default is 0.
