Even with RoCE2, some of the testing we did <br>
demonstrated very significant congestion related slowdowns that we <br>
couldn't easily tune for (with PFC and other bits that RoCE needs).<br><br>
I've used iWARP in the dim and distant past, and it was much better than <br>
plain old gigabit on the same systems (with Ammasso cards). --</div></div></div></div></blockquote>BTW, this gives the question about choice between RoCE vs iWARP. Does your "Even with RoCE2" means that iWARP is more bad than RoCE ? <br><br>Mikhail Kuzminsky,<br>Zelinsky Institute of Organic Chemistry RAS,<br>Moscow<br></BODY></HTML>
