Links of the day 17 - 04 - 2015

Today's Links 17/04/2015: Cluster management, Causal consistency , Lock-free architecture and when server memory get big
  • Borg : Large-scale cluster management at Google with Borg. It achieves high utilization by combining admission control, efficient task-packing, over-commitment, and machine sharing with process-level performance isolation. It supports high-availability applications with runtime features that minimize fault-recovery time, and scheduling policies that reduce the probability of correlated failures.
  • Efficient Virtual Memory for Big Memory Servers : interesting paper, too bad the premise are bad. If you have that type of application you should size and configure the server to avoid swapping. Moreover Transparent Huge Page is the must in these scenario. All in all , nice academic exercise but does not represent real production scenario.
  • Causal Consistency : nice post on the usage of causal consistency by the Jan Lindstrom of the mariaDB crowd.
  • lock-free architecture : built on queues allowing tasks to control their parallelism level easily from 1(synchronized) to N(parallel).
