numa_scheduling_groups
numa_scheduling_groups(4) Kernel Interfaces Manual numa_scheduling_groups(4)NAME
numa_scheduling_groups - Compaq Tru64 UNIX NUMA Scheduling Groups description (libnuma library)
DESCRIPTION
Normally, the kernel scheduler attempts to distribute the workload evenly over the entire machine. When the system resources are evenly
utilized, the machine is considered to be balanced. When balancing the workload, the scheduler operates in a context-free manner; that is,
processes may be distributed to various CPUs, or other resources, without regard to their function or relationship to one another. In cer-
tain cases, a user may wish to bundle a group of processes together so that they have equal access to the same system resources. For
instance, cooperating processes that share the same physical memory may perform better if all of these processes execute on CPUs that are
local to that memory.
NUMA Scheduling Groups (NSG) cause the scheduler load-balancing system to treat all members of an NSG as a unit. If one process belonging
to an NSG moves from one Resource Affinity Domain (RAD) to another, all other members of the NSG have to move with it.
NSGs and their members have the following characteristics: The resource domain of the first process joining an NSG provides the initial
resource domain location for that NSG, called the NSG home RAD. All other processes joining the NSG (through the nsg_attach_pid() func-
tion) will be migrated to the NSG home RAD. If the joining process is not allowed to migrate, the nsg_attach_pid() function will fail. To
support load balancing, an NSG is allowed to migrate to any RAD on the system if none of its members is bound to a specific resource (such
as another RAD, CPU, and so on). An NSG member is allowed to attach to or bind to a resource only if no other members are bound to differ-
ent resources. The entire NSG will migrate to the RAD containing the resource at the time it was successfully bound. If one NSG member is
bound to a resource, all other members of that NSG are also bound to the RAD containing that resource, because the NSG and, therefore its
members, is no longer allowed to migrate.
