About the Topic

As modern systems achieve performance targets by increasing the number of sockets and cores rather than increasing the processor bus speed, new architectures have been needed to integrate the processors to the memory subsystem.  This talk will present an overview of modern server memory architecture, including Non-uniform Memory Access (NUMA) systems.

These architectural changes have necessitated changes in the Linux kernel memory subsystem to react to these changes in server architectures.  The talk will also present an overview of the Linux kernel memory management structures and the changes that have taken place in it to evolve along with the architectural changes in computing hardware.
