Re: [Xen-devel] Re: NUMA and SMP

Thank you for your reply

in the smp with adm64 with the hardware of numa, its linux is a smp os ,then there is only one node (struct pglist_data) in the os when running or there are as many nodes as cpus in the system, does linux smp support two or more nodes when running? or in this case linux support numa feature?

the number of nodes corresponds to the number of memory areas which
allocators need distinguish. in the case of integrated memory
controllers like amd64, expect to find as many nodes as there are
yes, linux has numa support. see linux/Documentation/vm/

linux has numa support,and in the case of integrated memory controllers like amd64, CONFIG_NUMA should be choice and linux support numa,is it right? if CONFIG_NUMA is not choice ,then linux could not work well in the case of integrated memory controllers even for amd64,is it right? and for the paravirt xen-guest-linux do not support numa-aware now ,or does it support numa-aware if CONFIG_NUMA choiced?

Thanks in advance
