Context Before

CMX is NVIDIA’s context memory storage platform.

Evidence

CMX addresses a growing bottleneck in modern inference infrastructure: the rapid expansion of KV Cache required to support long-context and agentic workloads.

Context After

KV cache grows linearly with input sequence length and number of users and is the primary tradeoff when it comes to prefill performance (time to first token). At scale, on-device HBM does not have enough capacity. Host DRAM extends beyond HBM capacity with an additional tier of cache, but also hits limits on total amount per node, memory bandwidth, and network bandwidth. Enter NVMe storage for additional KVcache offload.

② Atomic Claim

CMX 用來處理現代 inference infrastructure 日益明顯的 bottleneck:支援 long-context 與 agentic workloads 所需的 KV Cache 快速成長。
