System Benchmarks

A set of benchmarks to measure critical system operations such as context switching time and the impact of using different scheduling policies on the context switching.

Context Switching

To measure context switching with different schedulers, change to folder context-switching and do:

• make
• ./cont_sw_exe -c <core> -s <sched_policy> -p <sched_priority>

Example usage:

./cont_sw_exe -c <core> -s [normal or batch]  -p [-19, 19]

./cont_sw_exe -c <core> -s [rr or fifo]  -p [1,99]

This repository was used to measure the time a modern server requires for context switching, in the context of network functions virtualization (NFV). An extensive study in NFV profiling along with experimental results are reported in our Elsevier journal article.
