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.
