Dynamic VRAM Availability and Memory Split Shifts in Edge MoE Serving
Unlike datacenter environments with dedicated hardware, edge devices share the GPU among concurrent consumer applications such as the desktop compositor, web browsers, and games, which dynamically claim or release gigabytes of VRAM. Consequently, the total VRAM available to an MoE serving engine fluctuates across launches and during execution. Furthermore, the optimal internal allocation of GPU memory shifts over time: as multi-turn agentic workloads accumulate conversational context, Key-Value (KV) cache demand grows substantially while the MoE expert working set remains relatively stable. A static division chosen at session start becomes mismatched over time, requiring serving systems to elastically adjust both their total VRAM footprint and its internal split between KV cache pages and expert slots at runtime without restarting the engine.

Which characteristic of edge hardware environments directly causes dynamic shifts in GPU memory availability for an MoE serving engine?
During multi-turn agentic workloads on edge devices, the MoE expert working set expands substantially while Key-Value (KV) cache demand remains relatively stable.
Explain why static GPU memory allocation is unsuitable for edge MoE serving, detailing both external device factors and internal workload dynamics.
When serving MoE models at the edge, internal GPU memory allocation must dynamically rebalance between which two resources as conversational context accumulates?
On consumer edge devices, the total VRAM available to an MoE serving engine remains static during execution once the engine finishes launching.
Compare the GPU execution environment of dedicated datacenters with that of consumer edge devices, and explain how the edge environment shapes the operational requirements for managing an MoE serving engine's overall memory footprint.
