[libfabric-users] sockets provider question

[Howard Pritchard]

Hi Folks,

We have a simple libfabric test we are trying to get to work.
It uses FI_EP_RDM endpoint type.  A single endpoint is
created.

The test is intended to send/recv messages on this single
endpoint.  This test works with GNI provider, but hangs
with the sockets provider.

We are working from master at 33cad4b

If we turn on FI_LOG_LEVEL_DEBUG we see odd things about
trying to use port 0 - which doesn't sound good:

libfabric:sockets:av:sock_check_table_in():228<debug> AV-INSERT:dst_addr:
family: 2, IP is 10.128.0.9, port: 0

libfabric:sockets:ep_data:sock_pe_add_tx_ctx():2435<debug> TX ctx added to
PE

libfabric:sockets:ep_data:sock_pe_add_rx_ctx():2453<debug> RX ctx added to
PE

libfabric:sockets:ep_ctrl:sock_conn_listen():311<debug> Binding listener
thread to port: 0

libfabric:sockets:ep_ctrl:sock_conn_listen():337<debug> Bound to port:
56165 - 39144

and later on when we try to send a message:

Test Fabric object created.

Attempting to send a message. You should see some output.


Sending...

libfabric:sockets:ep_ctrl:sock_ep_connect():419<debug> Connecting to:
10.128.0.9:0

libfabric:sockets:ep_ctrl:sock_ep_connect():421<debug> Connecting using

libfabric:sockets:ep_ctrl:sock_ep_connect():443<debug> Error in

libfabric:sockets:ep_ctrl:sock_ep_connect():445<debug> Connecting to:
10.128.0.9:0

libfabric:sockets:ep_ctrl:sock_ep_connect():447<debug> Connecting using
address:10.128.0.9

Are there known problems with the sockets provider and send-to-self style
send/recv
using FI_EP_RDM?

Thanks for any help,

Howard
