Introduction
uDAPL defines a single set of user-level APIs for all RDMA-capable transports. uDAPL also defines a
transport-independent and platform-standard set of APIs that takes advantage of RDMA capabilities
such as those present in IB. To obtain uDAPL, install the drivers. No additional configuration is required
to use uDAPL.
