APAR status

  • Closed as program error.

Error description

  • On systems with 1 CPU, when XLSMPOPTS=startproc=0 is set, the
    following message is output when the application runs:
    
    
    1587-138 the specified place list is invalid 'cores', reverting
    to default.
    
    
    The message is caused by the XLSMPOPTS default stride=0 setting,
    which is not a valid setting.
    

Local fix

  • Set XLSMPOPTS=startproc=0:stride=1
    

Problem summary

  • PROBLEM DESCRIPTION:
    For the case where stride is not specified or is 0, the default
    stride is set to 0, which is not a valid setting.
    
    USERS AFFECTED:
    Anyone using -qsmp and using XLSMPOPTS=startproc to bind
    threads to processors.
    

Problem conclusion

  • The default stride setting has been changed to 1 to avoid this
    issue and make XLSMPOPTS more intuitive.
    

Temporary fix
