Searching an appropriate scratch size can be difficult. The time specification is independend of the number of parallel workers.

Navigation and service

Typical unix commands for that are: Here, we got the “default” version 5. Attach file Files 0. Nevertheless M might be still too low for some Gromacs jobs.

Fixed corrupted energy and checkpoint file output with BAR free energy calculations.

Fixed a reverted version string in configure. Update for Gromacs Series 5. Rule of thumb in case of serial AND shared memory parallel jobs: Gromacs Homepage Gromacs Manual.

Again it requires experience to set this value appropriately. However, in the interests of clarity and completeness, some individual parts of GROMACS that can be used under their respective licenses are also noted here, too.

This version is known to be more stable than recent MKL-versions of Gromacs. Free energy writing to ener. Table of contents 1. Our Gromacs version is shared-memory parallel only. GROMACS supports all the usual algorithms you expect from a modern molecular dynamics implementation, check the online reference or manual for detailsbut there are also quite a few features that make it stand out from the competition.


Small fix to deal with possible overflows in dh binning. Cosmetic fixes for selection parsing. Updated html documentation for release 4. If you get problems with a big amount of calculations with newer versions, try this one! Output file appending at continuation is turned on by default. Usually there is no need to change the script default value of M. MD5sum are used to verify that all files are correctly in-place before a simulation is appended.

Optional computation of fluct. Made pdb2gmx -chainsep option work. Bennett acceptance ratio BAR free energy calculations, including automatic error estimates and phase space overlap measures. Added support for new mdp gfomacs controlling free energy perturbation output. Fixed broken linking with single precision fftw3 in CMake.

gromas Gridcount is an analysis tool for Gromacs that creates 3D number densities from molecular dynamics trajectories. The required memory might slightly depend on the number of workers e.

File mode for xdr3dfcoord is now derived from the XDR struct. If the speedup is not sufficient, it is better to run several smaller jobs with reasonable speedup side by side.

Gromacs – bwHPC Wiki

Added CT3 termini and minor edit in doc file. Library support for “dynamic index groups” based on textual selections experimental feature.


Added an uninstall target to CMake builds. Fixed CMake build with CMake 2. Added out int-extraction macro to double precision SSE2 intrinsics header too. Important settings are now detected directly from the compiler and environment, and non-important stuff has been removed or moved to source files.

Currently the maximal value is around 1. For memory stack specification see “ulimit -s” command below in this script.

Versions 4.5.x

All pages Main pages. Fixed issues in Generalized Mahual code that could cause incorrect results with all-vs-all and double precision SSE inner-loops. Fixed test particle insertion dispersion correction and PME contribution for multi-atom insertion molecules. 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.

Make sure that the memory specification in your Gromacs input file e. Shorter jobs might get higher priorities. Several files needed for CMake builds were missing in the distributed gromacs Fixed COM pulling with multiple constraints checking the convergence of one constraint instead of all.

All binaries are compiled including MPI. Fixed a segfault in selection code.
