NAME

       fi_net - The net Fabric Provider

OVERVIEW

       The  net  provider  is  a  developmental  fork  of  the tcp provider focused on improving performance and
       scalability 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
              protocol 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
              protocol 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
       application.   For  example,  “fi_info  -g  net”  will show all environment variables usable with the net
       provider.
