As we shift from CPU-centric computing to GPU-accelerated computing for supporting intelligent data processing at scale, the storage bottleneck has been exacerbated. To bypass the host CPUand alleviate unnecessary data movements, modern GPUs enable direct storage access to SSDs (i.e., GPUDirect Storage). However, current GPUDirect Storage solutions still rely on the host file system to manage the storage device, direct storage accesses are still bottlenecked by the host.
