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.

EasyBuild

The EasyConfigs are a development of the LUST team. As there are no release versions, we currently refer to commits.

Archived EasyConfigs

The EasyConfigs below are additonal easyconfigs that are not directly available on the system for installation. Users are advised to use the newer ones and these archived ones are unsupported. They are still provided as a source of information should you need this, e.g., to understand the configuration that was used for earlier work on the system.
