How-to determine the number of (physical) FPUs under both Windows and Linux?
The output of cat /proc/cpuinfo may contain (for example, stripped):
processor : 0
...
fpu : yes
processor : 1
...
fpu : yes
Here we see fpu : yes. Does it mean that each processor (logical core?) has its own (physical) FPU?
Reason for the question: is parallelization of an FPU intensive code running on modern multicore CPUs worth the effort?
