Revision as of 13:41, 21 October 2016
The bwUniCluster system will be unavailable between October 17, 2016 and October 21, 2016 for scheduled maintenance.
We strongly recommend to recompile all your binaries after the maintenance due to operational system as well as software and libraries upgrade. This does also apply to binaries that may have been built as add-ons for existing software modules, e.g. private packages for R and Octave, Matlab MEX files, etc.
The batch system queues will be closed starting a couple of days before the maintenance window and will then be cleared. Data on the parallel file systems will remain intact.
Contents
1 Operational System Upgrade
Upgrade from Red Hat Enterprise Linux Server release 6.8 (Santiago) to Red Hat Enterprise Linux Server release 7.2 (Maipo)
2 REPLACED SSH Host Key
The original SSH host key of bwUniCluster has been generated under Redhat 6 with DSA. Redhat 7 and latest SSH clients recommend improved key generation algorithm such as ECDSA and ED25519. Indeed, Redhat 7 has opted out DSA key generation. Following the recommendations the original SSH host key of bwUniCluster has been replaced with a new one based on ECDSA.
2.1 HowTo: Putty users
3 CHANGED Software Defaults
Software modules for which a newer version has been set as the default.
- chem/turbomole/7.0 -> chem/turbomole/7.1
- chem/tmolex/4.1 -> chem/tmolex/4.2
- devel/python/2.7.10 -> devel/python/2.7.12 (actually not the default but newest 2.7 release)
- devel/python/3.5.0 -> devel/python/3.5.2
- math/R/3.1.2 -> math/R/3.2.1 (or newer)
- compiler/intel/15.0 -> compiler/intel/16.0
- numlib/mkl/11.2.3 -> numlib/mkl/11.3.4
- mpi/impi/5.0.3-intel-15.0 -> mpi/impi/5.1.3-intel-16.0
- devel/itac/9.0.3 -> devel/itac/9.1.2
4 RECOMPILED Software Modules
Software modules which has been recompiled with different compiler or libraries
- phys/qutip/3.1.0
5 REMOVED Software Modules
Very old Intel compiler and related modules (which was available to all bwUniCluster users (/opt/bwhpc/common/modulefiles):
- compiler/intel/12.1
- compiler/intel/13.1
- numlib/mkl/10.3.12
- numlib/mkl/11.0.5
- mpi/impi/4.1.0-gnu-4.4
- mpi/impi/4.1.0-gnu-4.5
- mpi/impi/4.1.0-intel-12.1
- mpi/impi/4.1.1-gnu-4.4
- mpi/impi/4.1.1-gnu-4.7
- mpi/impi/4.1.1-intel-13.1
- devel/itac/8.1.1
- devel/itac/8.1.2
Note that all dependent modules and binaries will stop working thereafter. So rebuild your modules and/or binaries with newer versions of the Intel compiler.
5.2 Common software
Software that was available to all bwUniCluster users (/opt/bwhpc/common/modulefiles):
- chem/turbomole/6.5
- chem/turbomole/6.6
- chem/tmolex/4.0
- chem/molden/5.2.1
- math/R/3.0.2
- phys/qutip/2.2.0
- lib/matplotlib/1.3.1
5.3 Freiburg software
Software that was ONLY available to users from Freiburg (/opt/bwhpc/fr/modulefiles):
- chem/lammps/5Sep2014_linux
- chem/lammps/5Sep2014_mkl
- cns/nest/2.2.2-python-2.7.6_cns
- cns/nest/2.8.0-python-2.7.6_cns
- devel/cmake/3.0.1
- devel/python/2.7.6_cns
