Technical documentation

This is a plug-in for the RCCL library to use libfabric as a network provider in RCCL based applications. This plugin is essential to get good bandwidth and scalability in RCCL applications on the SlingShot 11 interconnect of LUMI. It was originally developed for the AWS EC2 network infrastructure, hence its name.

The plug-in maps RCCLs connection-oriented transport APIs to libfabric's connection-less reliable interface. This allows RCCL applications to take benefit of libfabric's transport layer services like reliable message support and operating system bypass.
