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
