Amber20 is now available!
We are pleased to announce the release (on April 31, 2020) of version 20
of the Amber software suite.
(How to order.) This represents a
significant update from version 18, which was released in April, 2018.
The Amber20 package builds on AmberTools21 by adding the pmemd
program, which resembles the sander (molecular dynamics) code in
AmberTools, but provides (much) better performance on multiple CPUs, and
dramatic speed improvements on GPUs.
