Computational needs in high energy physics applications are increasingly met by utilizing GPUs as hardware accelerators, but achieving the highest throughput requires directly reading data into GPU memory. This has yet to be achieved for HEP’s standard domain specific “ROOT” file formats. Using KvikIO’s python bindings to CuFile and NvComp, KvikUproot is a prototype package to support the reading of ROOT file formats by the GPU. On GPUDirect storage (GDS) enabled systems, data bypasses the CPU and is loaded directly from storage to the GPU. We will discuss the methodology we developed to read ROOT files into GPUs via RDMA.
