Nowdays, The speed of supercomputers are measured in Flops. Is there any linux command or tool that can calculate or gives the speed of a processor in Flops. If not, than how do we measure it.
It may not even be needed to calculate theoretical value to have a tool. Take a look at this article that describes it.
In actuality the measurement depends not only on hardware but also on the mathematical libraries you use for example in this question on Server Fault and an article on Wikipedia mentions LINPACK as a benchmarking tool, however, it may perform slightly differently when used with or without CPU optimized library
