Amber version 20 has been updated and installed with Intel and GNU compilers and MVAPICH2 on Owens and Pitzer. These include Amber and AmberTools. Usage is via the module amber/20. For installation details, such as, available packages and example batch scripts, use command: "module help amber/20". For help loading an installation, use command: "module spider amber/20".
We've been experiencing some instability on the clusters (particularly Cardinal and Ascend).
