Tutorial

Speakers: Rajalaxmi Angadi and Juee Himalbhai Desai (Intel)

Abstract:
OpenFabrics Interfaces (OFI) is a framework focused on exporting fabric communication services to applications. OFI is best described as a collection of libraries and applications used to export fabric services. The key components of OFI are application interfaces, provider libraries, kernel services, daemons, and test applications. Libfabric is a core component of OFI. It is the library that defines and exports the user-space API of OFI and is typically the only software that applications deal with directly. It works in conjunction with provider libraries, which are often integrated directly into libfabric. In this tutorial we would introduce OFI libfabric and briefly explain important libfabric APIs. To explain how these APIs can be used we would do a walk-through of a simple application that exchanges hello messages using (Reliable Datagram) RDM. This will then be proceeded to show more advanced aspects of libfabric such as tagged messages, remote memory access and memory registration modes. The tutorial will also show how libfabric stands out by having software interfaces co-designed with fabric hardware providers and leveraging and expanding existing RDMA open-source community.
