GROMACS 4.6 MANUAL PDF

If you have superuser privileges, then you will have the option of just installing to the default locations. If you have a site installation policy that prohibits this, or lack superuser privileges, or wish to maintain multiple GROMACS installations, then you will need to choose somewhere suitable to install. GROMACS is able to compile as a set of shared libraries, which greatly reduces the disk footprint of the installation, but this can be tricky on some platforms. If you encounter problems at the linking stages below, it is recommended that you configure everything for static libraries i. However prior to version 4. For modern Intel and AMD processors we provide faster loops written in assembler, so for those you should skip Fortran.

If you have superuser privileges, then you will have the option of just installing to the default locations. If you have a site installation policy that prohibits this, or lack superuser privileges, or wish to maintain multiple GROMACS installations, then you will need to choose somewhere suitable to install. GROMACS is able to compile as a set of shared libraries, which greatly reduces the disk footprint of the installation, but this can be tricky on some platforms. If you encounter problems at the linking stages below, it is recommended that you configure everything for static libraries i.

However prior to version 4. For modern Intel and AMD processors we provide faster loops written in assembler, so for those you should skip Fortran.

The gcc 4. If you want to run in parallel across a network, you need MPI. If you are running on a supercomputer you probably already have an optimized MPI version installed - consult your documentation or ask your system administrator. See below for information about how to make use of MPI. OpenMPI is recommended. You need an FFT library to perform Fourier transforms. Often a distro will provide only a double-precision version, and to get the full benefit of GROMACS performance you will need to install a single-precision version.

Note that this may mean installing packages with "-devel" suffixes if using your distro package manager. You may wish to do this if configure complains about FFT libraries, which are only available in double precision in some distributions. To compile a single-precision version of the libraries:. If you do not like that since you must have root permissions to write there , you can place them e. In some cases, it can also be useful to compile and install a double-precision version of the FFTW libraries.

This can be accomplished with: make distclean. It will be the only build system begining with 4. Most Linux distributions come with packages available through their corresponding package manager. Make sure you have version is 2. Using autoconf After installing and necessary prerequisites e. The process is very simple.

After unpacking the source code, configure the installation with:. The script will let you know about any problems. For versions 4.

Threading is useful only when all your cores are real i. These variables can be specified separately, in advance of configuration, or on the. Different CPU types will be installed in subdirectories below the architecture directory. Linux is a notable exception; we compile both non-assembly, SSE and sometimes 3DNow loops and select which one to use at runtime.

It compiles amazingly fast on a way SMP machine! Otherwise - sit back and wait for the package to compile. To adhere to modern Linux standards we have changed some subdirectories, and if you just install over the older files you risk ending up with a confusing mess of duplicate files and data.

This means you are trying to install somewhere that is not permitted for your user. Perhaps in the future, some of the utility programs may become MPI-aware, but these will only be for compute-intensive utilities e.

You may even run into more issues with shared libraries, so keep things simple! Note that you will then need to re-source your shell configuration file, or open a new shell in order to have the intended effect.

Having difficulty? Give details about the system on which you are installing. Copy and paste your command line and as much of the output as you think might be relevant - certainly from the first indication of a problem. Specialty Instructions.

Fri 29 Aug Description This program reads a. These files can subsequently be processed to generate a run input file. By default the forcefield selection is interactive, but you can use the -ff option to specify one of the short names in the list on the command line instead. After choosing a force field, all files will be read only from the corresponding force field directory.

Specifying the -pp flag will get the pre-processed topology file written out so that you can verify its contents. When using position restraints a file with restraint coordinates can be supplied with -r, otherwise restraining will be done with respect to the conformation from the -c option. For free energy calculation the the coordinates for the B topology can be supplied with -rb, otherwise they will be equal to those of the A topology. Starting coordinates can be read from trajectory with -t. The last frame with coordinates and velocities will be read, unless the -time option is used. Only if this information is absent will the coordinates in the -c file be used. However, for simply changing the number of run steps to extend a run, using tpbconv is more convenient than grompp.
