Dear NERSC SP users, Now that all NERSC users have moved from the Cray systems to the SP (seaborg), I would like to remind you of a few essential Web pages for SP users: - The primary NERSC SP page, http://hpcf.nersc.gov/ which provides the general introduction and overview of the system, including the hardware and the AIX Unix environment. - The xlf Fortran compiler page, http://hpcf.nersc.gov/software/ibm/xlf.html with a good overview of the compiler, environment and compiler options. This page includes links to pages discussion porting codes from Cray to IBM, and also IBM memory management issues. - The "running jobs" page, http://hpcf.nersc.gov/running_jobs/ibm/ with an overview of how to run interactive and batch jobs using LoadLeveler. This page includes a link to a discussion of the differences between Cray NQE/NQS and IBM LoadLeveler. - The file storage page, http://hpcf.nersc.gov/storage/ibm/ Please be aware that you should use $SCRATCH for your temporary storage. Do not use /tmp or /var/tmp as you did on the Crays. - The software page, http://hpcf.nersc.gov/software/ibm/ full of links to all software products available on the SP. NERSC is also offering a full day of training on the IBM SP on October 10. Please see http://hpcf.nersc.gov/training/classes/2002/Oct10.Day.html for more information.
