HI
I have a Red Hat Enterprise with Real Time kernel.
Are you aware if there are C functions for this kernel or some code/library for this OS for measuring time more lightweight than clock_gettime and gettimeofday? THe hardware I have is NUMA.
Reading forums I found gethrtime but it is available on Solaris only; this last spends few cycles compared to clock_gettime and gettimeofday eating the CPU.
Do you know if for Red Hat someomene did something similar?
My distro is the following
THanks a lot
