Network Direct SPI


Hardware vendors implement the Network Direct service provider interface (SPI) to expose the advanced capabilities of their networking devices and allow applications to leverage advances in industry-standard networking technologies, such as iWARP and InfiniBand, in addition to proprietary hardware.

The Network Direct architecture provides application developers with a networking interface that enables zero-copy data transfers between applications, kernel-bypass I/O generation and completion processing, and one-sided data transfer operations.

Developer Audience

The Network Direct SPI is designed for C++ developers.

Run-Time Requirements

The compute cluster node must have Microsoft Message Passing Interface (MS-MPI) installed.
