[Barrelfish-users] System knowledge base microbenchmarks?

Hi Barrelfishers,

"Embracing diversity in the Barrelfish manycore operating system"
says that Barrelfish will use (or uses?) a "system knowledge base" to
educate system-resource policies and derives the SKB using "online
measurement and profiling."  The paper specifically mentions application
benchmarking but does not explicitly mention the use of
micro-benchmarking.  It seems micro-benchmarking would be useful to
measure properties of the hardware system  (like  X-Ray [1]).  Does
Barrelfish use micro-benchmarks this way?
