I installed Gromacs 5.0.6, but while running mdrun, I got the error:
Program gmx, VERSION 5.0.6
Source code file:
/build/gromacs-yTV9IQ/gromacs-5.0.6/src/gromacs/gmxlib/gmx_detect_hardware.c,
line: 212

Fatal error:
The gmx executable was compiled to use the rdtscp CPU instruction. However,
this is not supported by the current hardware and continuing would lead to
a crash. Please rebuild GROMACS with the GMX_USE_RDTSCP=OFF CMake option.
For more information and tips for troubleshooting, please check the GROMACS
website at http://www.gromacs.org/Documentation/Errors

How to solve this problem ? Thanks.
