Problem summary
USERS AFFECTED: Users of XLSMPOPTS with the bindlist suboption may be affected by this issue. PROBLEM DESCRIPTION: An internal call creats an OpenMP instance which fails to binds the threads to the processes.
Problem conclusion
The XLSMP runtime has been fixed so that the threads are now bound to the processes.
