Adjusting to CentOS 7
If anything is no longer working now that the SCC has switched to CentOS 7, see if you can make changes to fix the issue.
Module Changes
We have installed many newer versions of software packages and many older modules are no longer available under CentOS 7. You may need to update your module load commands in your batch scripts. Run the module avail command to find the updated name/version of the packages you use. Updated versions and names for some packages are listed in these tables. If you do need to use an older version that we have not installed, email help@scc.bu.edu to request it.
Problems with your .bashrc File
If you get errors on login or are not finding certain packages or commands that worked in the past, you should take a look at your .bashrc file, located in your home directory. If you have made changes to it, such as adding module load or export commands to it, these may need to be adjusted for CentOS 7. If you have troubles with this, please email us at help@scc.bu.edu and we can help with your particular situation.
If you are using a shell other than the bash shell, you will need to look instead at your .cshrc file, .tcshrc, or .zshrc file and modify it appropriately. Note that under csh and tcsh, the command export is replaced by setenv. Our general page on Customizing your Environment may be helpful.
To reset your environment to the RCS default, you can run the command dotfiles to back up your existing dotfiles and install new dotfiles which should provide you with a good, basic working environment.
Problems with Compiled Code
Some programs will need to be recompiled under CentOS 7 in order to locate updated libraries. If your code is having any problems, please try recompiling it and see if it fixes the issues.
