QoS is supported only with ConnectX HCA, and not Inifnihost III Ex HCA. Also only from the coming FW release (2.3.0 that should be published soon) this feature will be enabled. Note that it will not be enabled by default and a FW configuration should be maid to use it Also a good explanation on QoS can be fount in the QoS Support <http://www.openfabrics.org/archives/nov2007sc/OFA_QoS_07.ppt> presentation by Sean Hefty, Intel; Dror Goldenberg, Mellanox under:
You must use OFED 1.3 to use QoS since it was not supported in OFED 1.2 Yevgeny will be able to help you regarding OSM setup to support QoS Tziporet ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mukil Kesavan Sent: Tuesday, December 04, 2007 7:08 AM To: [email protected] Subject: [ofa-general] OFED QoS Support Hi, I am a grad student at Georgia Institute of Technology working on Infiniband for a project. My focus is on IB QoS support. I used the OFED 1.2 distribution - opensm to configure the SL-VL mappings and the VLArb tables with the opensm.opts file in /var/cache/osm. Currently, I am configuring QoS as 1 high priority VL with weight 200 and disabling other high priority VLs. When I run the tests, there is no change in BW Avgs as per the QoS setting and it appears that BW is shared evenly among different applications during the tests. I currently use a Mellanox MT25208 Inifnihost III Ex HCA - Firmware version 4.6.0. Could someone help me getting the QoS to work? There are not a lot of resources on the web and I've been following the email exchanges amongst you guys involved in development but they aren't conclusive to me. Thanks for your time, Mukil _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
