commit 8df06af4810d8266839b36d3d5e43ee25ab9aeeb
Author: Su Huang <suhuang at us.ibm.com>
Date:   Wed Feb 5 16:41:56 2014 -0500

    Change the pamid default for advancing the scheduled NBCs
    
    In the pamid layer, mpir_nbc is set to 0 as the default e.g. the scheduled NBC
    work will not be advanced which would cause the job hang. The NBC would work
    only if the schedule is advanced. To do so, a user requires to set the
    environment variable PAMID_MPIR_NBC to 1.
    
    With MPICH 3.1 being released and NBC is one of support items in the release,
    the default for mpir_nbc should be changed from 0 to 1.
