Dear NERSC SP users, Please remember the following points about user file storage on seaborg: - NERSC cannot restore individual user files in your $HOME directory. You must backup your $HOME directory files to your HPSS account, preferably as one or more large tar files. - You should use $SCRATCH for your temporary workspace. Please make sure that all of your application and environment variables for temporary workspace also point to $SCRATCH, not /tmp, especially when migrating from the Crays. - Users should not use /tmp on the IBM SP seaborg. More information about the file systems of the IBM SP can be found on the Web at: http://hpcf.nersc.gov/storage/ibm/ IBM SP users who access HPSS should use the hsi utility for best performance. pftp and a non-cleartext ftp method are also available. More information about HPSS can be found on the web at: http://hpcf.nersc.gov/storage/hpss/ The NERSC Crays will be retired on October 1, 2002. If you need information about moving files from the Crays to the IBM SP, please see the Web at: http://hpcf.nersc.gov/computers/crayretire.html Best regards, Frank Hale NERSC Consultant
