The Barbershop Load Distribution
scheduler was announced back in 2012 while being announced today is a rare update to BLD.
BLD has been updated with a clean patch against Linux 3.16 as an alternative CPU load distribution technique for task scheduling. Besides re-basing to the latest stable kernel series, various improvements were made to its simplistic approach for load balancing. Standard x86 SMP multi-core systems should run BLD fine but not NUMA systems and your mileage may vary with how well BLD works for your needs.
To try out the BLD 3.16 release, the kernel patch can be found via this mailing list post
