NAME

       fi_net - The net Fabric Provider

OVERVIEW

       The  net provider is a developmental fork of the tcp provider focused on improving performance and scala‐
       bility of HPC/AI applications, without impacting the stability of the tcp provider.  It  will  be  merged
       back  into  the tcp provider at a later point in time.  See the fi_tcp(7) man page for additional details
       on the tcp provider.

SUPPORTED FEATURES

       The following features are supported

       Endpoint types
              FI_EP_MSG is supported by the net provider.  The net provider shares the same msg endpoint  proto‐
              col  as  the  tcp  provider.   FI_EP_RDM is supported directly by the net provider, unlike the tcp
              provider, which requires the use of the ofi_rxm utility provider.  The net  provider  extends  its
              msg endpoint protocol to support rdm endpoints.  As a result, the net provider’s rdm endpoint pro‐
              tocol is not compatible with the ofi_rxm;tcp layered protocol.

       Endpoint capabilities
              The net provider supports FI_MSG, FI_RMA, and FI_TAGGED.

       Shared Rx Context
              The net provider supports shared receive context

       Multi recv buffers
              The net provider supports multi recv buffers

RUNTIME PARAMETERS

       A  full  list of supported environment variables and their use can be obtained using the fi_info applica‐
       tion.  For example, “fi_info -g net” will show all environment variables usable with the net provider.
