Thank you Benson. These are very helpful.

Hi Yeping, A full build may be helpful to run the initial correctness tests, once you have done this can then use -DGMX_BUILD_MDRUN_ONLY=on for production runs. Having a full version of GROMACS on a node with access to the same file system where you do runs is also helpful since there may be features required for pre and post processing. If you have built your own MPI, you probably also want to use the flags: -DMPI_C_COMPILER=/path/to/your/mpicc -DMPI_CXX_COMPILER=/path/to/your/mpiccxx It may be helpful to name the MPI and Shared memory executables differently or install them in different places. The size of the system you are simulating will likely determine whether the MPI build will be useful for you. In most cases, the default -DGMX_DOUBLE=off is fine, The flag -DGMX_SIMD=xxx is also helpful, you will need to replace xxx with appropriate choice for your platform as indicated at: http://manual.gromacs.org/documentation/current/install-guide/index.html#simd-support Finally if you use ccmake rather than cmake, some of the other possible compilation options should appear.

For proper submission of task with PBS system, which options of cmake should I use? According to the "Quick and dirty cluster installation" section of the gromacs installation guide, it seems that a quick and dirty installation should be done, and then another installation with MPI should be done to the same location with the non-MPI installation. I am not very clear how these should be done exactly. Could you give the exact commands? Best regards Yeping Q <sunyep...@aliyun.com>; gromacs <gmx-us...@gromacs.org> Subject:Re: [gmx-users] How to install gromacs on cpu cluster Hi Yeping, Minimum required compiler version for the latest release is GCC 4.8.1 : http://manual.gromacs.org/documentation/current/install-guide/index.html GROMACS 4.5 seems to indicate support for GCC 4.5 (http://www.gromacs.org/Documentation/Installation_Instructions_4.5) Is CMAKE on your cluster? If so what version? Regards, Benson On 6/29/19 12:08 PM, sunyeping wrote: Hello Benson, Thank you for respond to my question. There is no GPU on my cluster.
