- Aug 18, 2026 Fixed-Slice Partitioning of Shared Engines Inside One Device Splitting a GPU into isolated instances without separate PCI functions requires slicing the caches and memory controllers, and the slices that cannot be cut set the floor on granularity. gpu computing
- Jun 10, 2026 Serializable Snapshot Isolation When Reads Span Several Shards How SSI tracks rw-dependencies to detect dangerous structures, why the conflict graph must be shared between shards, and what the read-only optimisation costs once reads are remote. distributed systems
- Jan 5, 2026 Global Snapshots Across Shards Without a Shared Clock How a transaction gets a consistent view of data spread over independent nodes, what a snapshot identifier must encode, and why the barrier between shards costs a round trip per query. distributed systems
- Oct 18, 2025 Throttling I/O with cgroup Controllers and What the Limits Share How the I/O controller accounts and limits bandwidth and IOPS per group, why a throttle applies to a queue rather than to a process, and how the limits interact with the page cache and with each other. performance engineering
- Sep 20, 2025 Covert Channels That Survive Logical Isolation Why a sandbox that prevents every direct access can still carry information through shared caches, timing, and resource contention, and what the bandwidth of each channel implies for policy. language runtimes
- Jun 26, 2025 How Seven Namespaces Compose Into a Container Each namespace type isolates a different resource table, and the order and ownership of unshare calls determine what a process can still see. virtualization
- Apr 26, 2025 Container Images as Frozen Environments and Their Limits Layer digesting, reproducibility of the build itself, kernel sharing, and the hardware facts a container cannot pin down. scientific computing
- Apr 23, 2025 Bulkhead Isolation and the Design of Partial Degradation Partitioning capacity so one dependency cannot consume all of it, and deciding in advance which features are worth serving when the partition is full. backend systems
- Jul 24, 2024 What a Namespace Isolates and What It Leaves Shared The eight namespace types, the resources each one partitions, and the state that stays global no matter how many namespaces a process joins. virtualization
- Feb 22, 2024 Prefix-Based Environments and Why Activation Is Only Path Surgery How a virtual environment isolates packages by rewriting interpreter paths and sys.path, why moving one breaks its scripts, and what containers change about the same problem. language runtimes
- Jul 9, 2023 Tenant Isolation and the Channels Performance Interference Travels Through Separating address spaces does not separate throughput; the shared resources that remain determine how much one tenant can slow another and which controls can bound it. gpu computing
