Compilers and libraries that CHPC suppport are available from the following folders:

• compilers: /opt/gridware/compilers
• libraries: /opt/gridware/libraries

You can also use Intel compilers by adding the following modules:

or sunstudio and gnu

Applications like gaussian and amber have their own modules Here is an example on how to use an amber at CHPC :

module list
module avail
module add intel
module add amber

Note that CHPC only support applications that are installed in /opt/gridware/applications

We discourage users from installing any applications on their home directories. Users can install their own applications in /opt/gridware/users/ which will also not be supported by CHPC.
