description The project aims at enabling the use of HPC (High Performance Computing) resources for HEP (High Energy Physics) software and will be carried out in the context of XRootD, a software framework widely used in the HEP community. In particular, we explore the possibility of using RDMA (Remote Direct Memory Access) as a transport layer for the xroot protocol. As a case study we will exchange data between two nodes of a RDMA enabled cluster. Two possible implementation approaches will be investi-gated, namely the use of the libfabric and librdmacm libraries. This report explains the basics about the XRootD protocol, RDMA and librdmacm library, and discusses a source code for transfering data over RDMA.
