S-LoRA/S-LoRAArchived
S LoRA
S-LoRA is a serving engine and execution framework built for hosting massive collections of task-specific language model adapters simultaneously on shared graphics hardware. It functions as a multi-tenant platform capable of managing thousands of concurrent fine-tuned adapters while maintaining high throughput and low overhead.
The platform relies on dynamic adapter weight scheduling to route incoming requests and swap weights on demand, paired with a shared dynamic memory pool that allocates video memory to handle varying adapter ranks and sequence lengths without fragmentation. Custom heterogeneous batched kernels execute mixed adapter ranks and non-contiguous memory spaces within a single unified compute batch, while a specialized tensor parallelism strategy overlaps communication overhead directly with base model operations to maximize multi-GPU scaling efficiency.
