The Gromacs 4 core reaches version 2.27

By , the in Folding@Home Project - No comment
Kyle Beauchamps has released a new version of the Gromacs 4 core, more commonly known as Core a4. This version upgrades the Gromacs software to version 4.5.3, giving the researchers more analysis methods.

This core is available for Windows (32-bit) and Linux (32-bit and 64-bit). For the avoidance of doubt the Windows core runs fine on 64-bit Windows ;)

No projects currently require the new revision, however if you wish to force the update then deleting your copy of the a4 core will cause the new version to be downloaded for the next unit that requires core a4.

If you choose not to upgrade now, it will be performed automatically the first time you receive a project needing the newer core.
