Yes; it covers all the parts to create a network connection, simplest definition is probably "The communications network MPI constructs either by itself or using a daemon". So it covers if you are using IB, ethernet, and so on in particular. In this case they are Infiniband connections using an OFA layer. A connection can include the authentication method and process, the hardware used to pass messages, the protocol used, which libraries and even which compiler was used in the most general usage. _______________________________________________ Manage your clamav-users mailing list subscription / unsubscribe: https://lists.clamav.net/mailman/listinfo/clamav-users Help us build a comprehensive ClamAV guide: https://github.com/Cisco-Talos/clamav-documentation https://docs.clamav.net/#mailing-lists-and-chat
