4 |Gromacs| 2018 was released on January 10, 2018. Patch releases may
5 have been made since then, please use the updated versions! Here are
6 some highlights of what you can expect, along with more detail in the
9 As always, we've got several useful performance improvements, with or
10 without GPUs, and all enabled and automated by default. We are
11 extremely interested in your feedback on how well this worked on your
12 simulations and hardware. They are:
14 * PME long-ranged interactions can now run on a single GPU, which
15 means many fewer CPU cores are needed for good performance.
16 * Optimized SIMD support for recent CPU architectures:
17 AMD Zen, Intel Skylake-X and Skylake Xeon-SP.
19 There are some new features available also:
21 * The AWH (Accelerated Weight Histogram) method is now supported,
22 which is an adaptive biasing method used for overcoming free energy
23 barriers and calculating free energies (see
24 http://dx.doi.org/10.1063/1.4890371).
25 * A new dual-list dynamic-pruning algorithm for the short-ranged
26 interactions, that uses an inner and outer list to permit a longer-lived
27 outer list, while doing less work overall and making runs
28 less sensitive to the choice of the "nslist" parameter.
29 * A physical validation suite is added, which runs a series of short
30 simulations, to verify the expected statistical properties,
31 e.g. of energy distributions between the simulations, as a sensitive
32 test that the code correctly samples the expected ensemble.
33 * Conserved quantities are computed and reported for more integration
34 schemes - now including all Berendsen and Parrinello-Rahman schemes.
