<DIV><FONT face=Arial size=2><SPAN class=806061802-01052007>We had not tried
submission SDP to kernel.org.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=806061802-01052007>The current SDP
performance is not very good.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=806061802-01052007>IPOIB connection
mode has much better bandwidth.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=806061802-01052007>But SDP has better
latency and less overhead.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=806061802-01052007>IPOIB connection
