What is uDAPL?
The User Direct Access Programming Library (uDAPL) defines a single set of user APIs for all RDMA-capable transports. The uDAPL is defined by the DAT (Direct Access Transport) Collaborative which is an industry group that has formed in order to define and submit for standardization a set of transport-independent, platform-independent Application Programming Interfaces (APIs) that exploit the RDMA (remote direct memory access) capabilities of next-generation interconnect technologies such as InfiniBand, the Virtual Interface Architecture and iWARP.
