OpenSFS project process has both HLD and DLD in design phase.</div><div>- the HLD described this feature as a single project, I'm wondering if it's possible to have multiple phases for it (or sub-projects), which will make it more manageable.</div><div>- it's worked out three years ago and core LNet has been changed a lot, it could be worth taking time to review it and consider if there's any new complexity or issue based on the latest LNet, i.e: Any potential SMP performance issue if adding this feature.</div><div><br></div><div>Regards</div><div>Liang</div><br><div><div>On Sep 21, 2012, at 4:38 AM, John Carrier wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: -webkit-auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; font-size: medium; "><div lang="EN-US" link="blue" vlink="purple"><div class="WordSection1" style="page: WordSection1; "><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; ">Hi all,<o:p></o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 10.5pt; font-family: Consolas; ">Since LNET channel bonding has made it to the TWG's short list of requirements for 2013, I would like to remind the community that Cray already funded the design of such a requirement in 2009.
