Userspace Scheduler Microbenchmark
|
|
##################################
|
|
|
|
This is a scheduler microbenchmark, designed to measure minimum
|
|
latencies (not scaling performance) of specific low level scheduling
|
|
primitives independent of overhead from application or API
|
|
abstractions. Contrary to the non-userspace version, it runs threads
|
|
in userspace with different memory domains.
|
|
|
|
It works very simply: a main thread creates n "yielders"
|
|
threads at a higher priority, from this initial state:
|
|
|
|
1. The main thread starts all yielders
|
|
2. Each yielder yields k times
|
|
5. The main thread joins all yielders
|
|
|
|
This is run for multiples values of n, reporting each time the
|
|
average time taken for a yield context switch.
