Michael, PSM is a specific feature of the QLogic (now Intel) line of Infinipath HCAs, to does not work with Mellanox HCAs. The congestion and routing abilities in PSM also require using the QLogic/Intel subnet manager.
From: ewg-boun...@lists.openfabrics.org [mailto:ewg-boun...@lists.openfabrics.org] On Behalf Of Michael Zhang Sent: Tuesday, June 26, 2012 11:41 PM To: ewg@lists.openfabrics.org Subject: [ewg] Questions about CC in OFED Hi everybody, 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. 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? Thank you for your help!
