RE: Processor affinity

Yes, its possible to determine which physical CPU's the VP's run on. We are running Sun Solaris as our O/S and it looks like you might be also. Using the pbind command, I can list which physical CPU's process are bound to. Then, using onstat -g sch, get the pid's of the oninit process we are running and map that to the output of pbind. Example : /u/informix$ pbind process id 12961: 0 process id 13060: 2 process id 13061: 3 process id 13059: 1 /u/informix$ onstat -g sch |grep cpu 1 12961 cpu 3 13059 cpu 4 13060 cpu 5 13061 cpu I have never seen those errors codes associated with binding. > -----Original Message----- > From: Sadagopan, Sathish, CFCTR [SMTP:sadagop0458@att.com] > Sent: Thursday, March 11, 1999 4:26 PM > To: informix-list@iiug.org > Subject: Processor affinity > > Hi, > Is it possible to determine which physical CPU's the VP's run on. > I have 6cpu vp's running on an 8 processor machine,with CPU vp affinity. > > The message log reads " Can't affinity VP 1 to phy proc 0 errno 4,Can't > affinity VP 3 to phy proc 0 errno 62...." > errno 2 is "interrupted system call" > errno 62 is "timer expired" > Everything else is ok. > > So , In this scenario how are CPU vp's scheduled across processors ? > TIA > Sathish Sadagopan
