Hi,
I installed the OFED1.2 stack and am trying to run a simple socket server

and client over the SDP stack. The Infiniband hardware is QLogic.
First I set the ENV vars

export LD_PRELOAD=/root/zulfi/iband/INSTALL/lib64/libsdp.so

export LIBSDP_CONFIG_FILE=/home/zulfi/libsdp.conf
The SDP config file has:

use sdp server * *:*

use sdp client * *:*
Then started the socket server and did a 'sdpnetstat -San' and found that it

listed the SDP port on which the server was listening.
On the client machine too I did the same; exported the variables, setup the

SDP config file and on running the client './client port# server_machine' it

gave me a "network not reachable" error.
I tried to get some information about the error on the net but could not

find any.
I then checked the /proc/<pid>/maps file and found that libsdp.so was being

loaded.

also:

/root > lsmod | grep sdp

ib_sdp                120224  3
Does QLogic support SDP applications ? Or am I missing something in the SDP

config file or do I need to make changes to my code ?
Any information on this will be a big help.
Thanks,

Zulfi

Were you able to connect IPoIB between the nodes? Are you sure opensm was running? I am ashamed to admit that occasionally I
forget to start opensm and wonder why SDP does not connect.

Does a simple "ping" between the nodes is working?
(this way you can be sure that IPoIB is working and SDP should work)

does this mean that the apps would now use IPoIB ? How do i tell when IPoIB

is working and when it isnt ? Because I assume when it isnt it would default

to Ethernet ?
It will be great if I can get this cleared.

I would then use strace with the client to watch the socket system calls
