Greeting NERSC SP User, On Wednesday, December 15, NERSC will be moving all home directories to a new file system. While the exact configuration of this file system is still under review, there is one issue that users need to be aware of: THE ABSOLUTE PATHNAME OF HOME DIRECTORIES WILL CHANGE. All users should verify that they are using the $HOME environment variable in shell scripts, makefiles, batch scripts, etc. Explicitly using values such as "/u4/myname" or "/usr/common/homes/m/myname" will fail beginning on December 16. Seaborg will be drained until 16:00 on December 15; any remaining running batch jobs will be killed. Home directories will then be copied to the new file system. The batch system will begin running jobs after the new file system is in place. Any job that refers to the old home file system will fail. If you have any questions, please contact NERSC consulting at: 1-800-66-NERSC, menu option 3, 8 am - 5 pm, Pacific time (510) 486-8600, menu option 3, 8 am - 5 pm, Pacific time consult_at_nersc_dot_gov http://help.nersc.gov/ -- Best regards, David Turner User Services Group email: dpturner@lbl.gov NERSC Division phone: (510) 486-4027 Lawrence Berkeley Lab fax: (510) 486-4316
