Autoscaling Lakebase Postgres

Choosing a database instance size without prior knowledge of the workload can lead to inefficiencies and excessive compute usage. Lakebase Postgres addresses this with an autoscaling feature that eliminates manual sizing, utilizing in-place VM resizing and a monitoring algorithm for CPU, memory, and working set size. Lakebase Postgres separates compute and storage layers, allowing independent resizing of compute nodes without affecting the database. The autoscaling algorithm relies on three signals: CPU load (cpuGoalCU), memory use (memGoalCU), and compute-cache working set size (lfcGoalCU). The CPU load is monitored every five seconds, aiming to maintain it at or below 90% capacity. Memory usage is tracked at two frequencies: overall memory every five seconds and Postgres-specific memory every 100 milliseconds, with a goal to keep usage below 75% of allocated RAM. The compute cache evaluates active data access efficiency, adjusting size based on workload. The working set is estimated using a modified HyperLogLog algorithm that records timestamps for page accesses, allowing for distinct page estimates over various time frames. The algorithm projects future working-set growth to allocate sufficient cache while capping it at 75% of RAM. Resizing the compute involves four components: the autoscaler-agent, vm-monitor, Kubernetes scheduler, and NeonVM. Scaling up occurs when any of the three goals indicate a need for more resources, while scaling down includes verification to ensure sufficient memory remains for operations. Timely adjustments in both directions are prioritized to minimize costs.

Your GPU’s scheduling toggle was pointless in 2020, and a growing list of Windows features now need it

For over a decade, Windows managed graphics card operations through a single CPU thread. In May 2020, Microsoft introduced Hardware-Accelerated GPU Scheduling (HAGS), allowing users to transfer scheduling tasks to the GPU. HAGS shifts scheduling from the CPU to a dedicated processor on the GPU, reducing CPU overhead. The introduction of WDDM 3.0 with Windows 11 21H2 requires HAGS for the basic hardware flip queue, which reduces power consumption. The advanced hardware flip queue, which addresses presentation latency, also requires HAGS. With Windows 11 24H2 and WDDM 3.2, native GPU fences were introduced, allowing the GPU to manage dependencies without CPU intervention. Nvidia's frame generation features require HAGS, while Intel's Arc B-series cards do not. The state of HAGS is determined by GPU drivers, and applications like OBS have shown caution towards HAGS due to historical issues.

Windows picks the wrong CPU cores for your games, and your processor has been telling it which ones to use

Modern processors, such as those from AMD, feature distinct cores with varying capabilities, allowing them to communicate their performance potential to the operating system via the Advanced Configuration and Power Interface (ACPI). This enables efficient resource allocation, particularly important for gaming, where a game may rely heavily on one or two threads. While Windows generally manages CPU resources effectively, issues can arise if the firmware fails to accurately convey core capabilities, leading to performance problems. Regular BIOS updates are crucial to ensure the CPU's preferred-core hierarchy is correctly communicated. Manual core assignment is usually unnecessary and can be counterproductive, as Windows' built-in scheduling is typically sufficient for most users.
