<p class="MsoNormal">Hi everybody,<o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal"> I focus on the source code of IB congestion control in OFED, such as CCT related data structure and FECN/BECN process. But the only code related to the congestion control mechanism is found in the module of "infinipath-psm". As I know,
psm works for MPI applications and actually I haven't installed psm in our system. I have done experiment through IPoIB and the congestion control still works that makes me confused.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"> Could someone tell me where is the CC-related source code located besides "infinipath-psm"? Or some functions are realized in hardware such as the movement of CCT Index when receives BECN message?<o:p></o:p></p>
</div>

<p class="MsoNormal"> Thank you for your help!<o:p></o:p></p>
