I am basically using the code inside vstat_main.c in the function vstat_get_counters - so PortSelect and CounterSelect are the same values(portnum and 0xFF respectively), I only changed the mad_in->method from IB_MAD_METHOD_GET to IB_MAD_METHOD_SET.

So if I understand correctly the version that I have does not manage the performance counters. According to what you say I also understand that future versions of the OpenSM will have Performance Manager that manages the performance counters - am I correct? If so in which version of WinOF is this planned for? Also, when talking about bundled performance managers - do they automatically reset the counters if they hit the limit, do I interact with them in order to get/set values for the performance counters?

In general, there can only be one performance manager owning a node's performance counters (assuming they are going to do resets as above). PerfMgrs come bundled in a number of different SMs. A more recent OpenSM than what is current in Windows has this as do most if not all vendor SMs. -- Hal > Thanks, > > Moshe. > > > > > ______________________________________________________________________ > > From: Tzachi Dar [mailto:[EMAIL PROTECTED] > Sent: Sunday, April 27, 2008 5:51 PM > To: Moshe Haim; [email protected] > Subject: RE: [ofw] Programatically checking Infiniband performance > counters > > > > > Using performance counters currently only allows one to get WSD data. > Since you are working on XP that won't help you.
