Title:
Yakkety Server cannot handle more than 256 cores
Status in linux package in Ubuntu:
Incomplete
Bug description:
Generic Linux kernel flavor is official Ubuntu Server Linux kernel flavor.
It is supposed to be run on both workstations and servers.
Generic kernel configuration supports max 256 CPUs:
root@ubuntu02:~# grep CONFIG_NR_CPUS /boot/config-$(uname -r)
CONFIG_NR_CPUS=256
While running on Intel KNL with Hyper-Threading enabled it cannot
accommodate cores over 256.
Probably server flavor should support 512 cores, like it is in RedHat.
Logs attached.
