TurboSparse eliminates im2col by executing SpConv directly over a DNN-oriented sparse format to reduce data movement and improve reuse, introduces row-merging micro-kernels guided by an analytical SIMD-utilization model to increase vector-lane occupancy, and fuses consecutive sparse kernels when their combined working...

LLM-based language services (e.g., summarization, translation, and question answering) require low-latency and cost-effective inference, yet GPU resources may be costly, unavailable, or difficult to integrate in many deployments. Many-core CPUs provide a flexible alternative, but achieving efficient inference requires...
Mixture-of-Experts (MoE) inference is increasingly deployed in local and on-premise environments, where expert parameters often exceed GPU memory capacity. In latency-sensitive, low-concurrency settings, repeatedly staging routed-expert weights from CPU memory to the GPU can be prohibitive, leaving routed-expert feed-f...

This work presents AsymFlow, a prefill-decode disaggregated serving system that runs prefill on the GPU and decode on the CPU, and implements on SGLang and evaluated on a CPU-GPU platform.

Driven by cost and privacy constraints, many organizations deploy large language model (LLM) inference on local CPU-GPU servers. For long-context requests, the key-value (KV) cache grows linearly with sequence length and can rapidly exhaust GPU memory, reducing both the maximum supported context and request concurrency...
