Supercomputer users: Moving from HLRB-II to the SuperMUC migration system

[LRZ aktuell]

Dear users of the HLRB-II at LRZ,
 
 The initial installation of the next-generation system, SuperMUC, is
 nearing regular user operation. As described in ALI 4069, the system
 has a computational power which is roughly equivalent to that of
 HLRB-II. LRZ has fixed the following time schedule for migration of all
 users from HLRB-II to the new system:
 
  1. On the afternoon of September 13, all HLRB-II users gain access to
     the new machine
  2. Between Sept. 13 and end of October, both HLRB-II and the new
     system will be online and available for batch processing
  3. At the end of October, HLRB-II will be retired from user operation.
     Please note that at this time there will be an interruption of
     operation for all HPC systems for a few days because the data on
     the HOME file systems need to be migrated to a new and much more
     powerful file server; precise dates will be announced separately.
 
 Please note that beginning on September 10, LRZ will only receive
 limited maintenance for the HLRB-II. In particular, it may happen that
 the system loses partitions, or that the $OPT_TMP or $PROJECT file
 system is completely removed in case a critical part fails, if the
 replacement costs are considered unacceptably high. For this reason, we
 urgently recommend that you archive all still needed HLRB-II data which
 reside on the $OPT_TMP or $PROJECT file systems to TSM tape storage as
 soon as possible.
 
 A procedure for migrating your scratch and project data from HLRB-II to
 the new system is described in the backup and archiving document for
 the HPC systems; please look at the scenarios 2 and 3 for details on
 how to perform the data migration. The $HOME file system will access
 the same NAS space on both systems, hence you do not need to migrate
 any data from there yourself.
