OSC is refreshing the software stack on Oakley on September 15, 2015 (during the scheduled downtime); something we have not done since Oakley entered service in 2012. During the software refresh, some default versions are updated to be more up-to-date and some older versions are removed. Information about the old and new default versions, as well as all available versions of each software package will be included on the corresponding OSC software webpage. See https://www.osc.edu/supercomputing/software-list.
Summary of Changes
- New versions of the compilers and MPI have been installed and will become the defaults. Libraries will be rebuilt with the new default compilers and MPI. The newest stable version of each library will be used in most cases.
- For software applications, the latest installed version will become the default in most cases, but the current default version will be kept and can be requested explicitly. New versions of some applications will be installed (which is done by request). Some old versions will be deleted (but not the current default version). Details are given in the tables below.
- Licenses that are currently restricted to Glenn, specifically ansyspar licenses (parallel Ansys/Fluent/CFX), will be moved to Oakley in preparation for retirement of the Glenn cluster.
- Some behind-the-scenes changes will be made to the module system. These changes won’t affect most users. Contact OSC Help if you experience problems.
Impact on User-Built Software
If you compile and link your own software you need to be particularly aware of the changes in the default modules. You will probably need to either rebuild your software or explicitly load the compiler and MPI modules that you built your code with before you run the code.
module load modules/au2014. This environment was the default environment at login on Oakley from 2012 to 9/15/2015. If your code is built with compilers other than Intel compiler, you can explicitly load the default module prior to 9/15/2015 using the command
module load name. Please refer to Compilers/MPI or the corresponding OSC software webpage (See https://www.osc.edu/supercomputing/software-list) for more information.
The following table gives details about the upcoming changes to software applications. All version numbers refer to actual module names. Applications not listed here will remain unchanged.
