    Affinity issue with Dual Xeon E5-2667 v3 Processor


      Hi All,

      Our system configuration is as follows:

      CPU Type: Intel(R) Xeon(R) CPU E5-2667 v3 @ 3.20GHz X 2 //Dual CPUs

      Motherboard Name: X10DAI

      Motherboard Version: 2.0

      Total Physical Memory: 65411MB Kingston RAM

      BIOS Manufacturer: American Megatrends Inc

      SSD: INTEL SSDSC2BW240H6 , 240GB, Intel 535 Series

      Operating System: Windows 7 Professional 64 Bit


      We have our application(of USB3 cameras,motion cards and IO applications) of 24 thread.When we run on system with both CPU enable sometimes(randomly) it gives error regarding camera bandwidth issue at startup,If no error at startup then there won't be until we stop application.But when we set affinity to either one CPU (run application to only one CPU)then we do not see such error.looks some synchronization issue between two processors.Is there any parameters to take care between two processors from BIOS or elsewhere ?


      Thanks in Advance!
