Gromacs Homepage Gromacs Manual. Changed the way energy conservation bookeeping is done.

Shorter jobs might get higher priorities. AmberGS force field is now based on Amber94 instead of Amber Tested and appears to work for normal interactions, GB testing in progress. Fixed a reverted version string in configure. The module will try to load modules it needs to function e.

Output file appending at continuation is turned on by default. Cleaned up all installed headers to remove strict dependence on config. Made tutorial slightly less confusing. Added missing NULL in chainsep enum in pdb2gmx. Gridcount is an analysis tool for Gromacs that creates 3D number densities from molecular dynamics trajectories. Furthermore it might be possible to extrapolate the run time by looking at smaller test jobs.

Small fix to deal with possible overflows in dh binning. Fixed possible inconvenient npme node choice with pme load between 0.

Highly efficient all-vs-all assembly kernels for both vanilla and generalized born interactions, in vromacs single and double precision. All binaries are compiled including MPI. Views Page Discussion View source History. For memory stack specification see “ulimit -s” command below in this script.

For a given number of processes or threads this tool systematically times mdrun with various numbers of PME-only nodes and determines which setting is fastest. Fixed issues in Generalized Born code that could cause incorrect results with all-vs-all and double precision SSE inner-loops.

Typically, this is used to look at the density of water or ions near proteins or in channels and pores. The bwForCluster default memory stack size 10M is too low for Gromacs.

Optional computation of fluct. Changes that might affect your results grompp by default sets the new nstcalcenergy parameter equal to nstlist, this has no effect on the integration, only on the energy averages stored in ener. Trying to get vscale working with vv. Rule of thumb in case of serial AND shared memory parallel jobs: Running on a multi-core node now uses thread-based parallelization to automatically spawn the optimum number of threads in the default build.


If the speedup is not sufficient, it is better to run several smaller jobs with reasonable speedup side by side. Fixed corrupted energy and checkpoint file output with BAR free energy calculations.

Much better support for nucleic acid simulations, including automatic handling by pdb2gmx. Proposed fix for v-rescale and berendsen for velocity verlet by rescaling at the time of coupling.

Library support for “dynamic index groups” based on textual selections experimental feature. Fixed broken linking with single precision fftw3 in CMake. Release notes for 4. Increase the number of workers starting with 1, 2, 4 and 8 cores and check for a reasonable speedup. One strategy is to calculate smaller jobs and extrapolate to larger jobs or one can run a job for some time in the foreground and monitor the disk usage.

Versions 4.5.x

Existing tools have not yet been converted. Fixed reuse of variable as temp variable before printing results. Enable the Reference platform for OpenMM.
