After BFS, Now Comes The BLD Linux Scheduler

Adding to the already existing Linux schedulers, including the out-of-tree Brain Fuck Scheduler (BFS), is now a proposal to integrate a new scheduler... The Barbershop Load Distribution scheduler.

Rakib Mullick announced the Barbershop Load Distribution (BLD) algorithm scheduler to the Linux kernel mailing list on Sunday.

The Barbershop Load Distribution method is described as "it only tries to distribute the load properly by tracking lowest and highest loaded rq of the system. This technique never tries to balance the system load at idle context, which is done by the current scheduler. The motivation behind this technique is to distribute load properly amonst the CPUs in a way as if load balancer isn't needed and to make load distribution easier."

Additional details on this experimental BLD Linux kernel scheduler can be found in this LKML message.
