User-level Direct Access Programming Library (uDAPL)
User Direct Access Programming Library (uDAPL) is a direct-access framework to be run on transports that support direct data access, such as InfiniBand and RDMA network interface controller (RNIC).
The DAT Collaborative specifies the uDAPL application programming interface (API). The uDAPL codebase from Open Fabrics is ported to AIX operating system and is supported over GX++ HCA and 4X DDR Expansion card (CFFh) InfiniBand adapters.
