[cs615asa] HW#N: Attended a relevant Meetup/Talk/Community event

[Vinod Tiwari]

Hello All,

I had attended a meet up on Virtual Memory Management & Virtualization in Linux at NYLUG, Civic Hall, 5th Avenue, NYC on March 16, 2016. Speaker Andrea Arcangeli provided a high level perspective of the most notable milestones in the longterm evolution of the Linux Virtual Memory and Virtualization subsystems. In addition, he explained recent advances in Memory Management related to the KVM Virtualization Hypervisor, such as THP, KSM, NUMA balancing, and userfaultfd/postcopy live migration. He covered best practices, providing the audience with an understanding of when and how to leverage these features in their environments.

I was always interested in learning about virtual memory management in unix environment. The talk was highly technical and I could not understand each and every part of it. Some of the topics discussed were:

Virtual Memory Evolution since '99
Virtual Memory and pageables
Physical page and struct page
Page reclaim clock algorithm
Page scan clock algorithm
LRU in virtual memory environment
RMAP over Pgtable scan clock algorithm
Virtual memory trends such as Numa balancing, Transparent Hugepages, KSM, MMU notify

Some of the topics were discussed from Redhat virtualization tuning and optimization guide
