<DIV dir=ltr><FONT face=Arial size=2>If you are using OFED 1.1 release, you will find a "README.txt" file (/usr/local/ofed/ directory). In this file, configuration steps of SDP are mentioned. </FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2>1. modprobe ib_sdp</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2>2. export LD_PRELOAD=/usr/local/ofed/lib/libsdp.so</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2>3. export LIBSDP_CONFIG_FILE=/usr/local/ofed/etc/libsdp.conf <application name>. </FONT></DIV>
