New Blog: How AIX Really Handles Concurrency & SMT8 Under Load

  • 1.  New Blog: How AIX Really Handles Concurrency & SMT8 Under Load

    Posted 2 days ago

    Ever wondered how AIX keeps systems stable under extreme pressure?
    I just published a deep-dive on how the AIX kernel manages concurrency, thread scheduling, NUMA locality, and SMT8 on IBM Power Systems.

    *
    The blog breaks down:

    • The multi-layered AIX concurrency model
    • How the scheduler decides where threads run
    • Real SMT8 behavior in demanding workloads
    • Why NUMA locality changes everything
    • Kernel safeguards that keep AIX stable at high load
