Dear all, When I compile gromacs using cmake, no large file related option was found in the cmake interface, however, I found the option for large file support in the CMakeCache.txt listed as bellow. ..... //Result of TEST_BIG_ENDIAN GMX_INTEGER_BIG_ENDIAN:INTERNAL=0 //Result of test for large file support GMX_LARGEFILES:INTERNAL=1 ......
I wonder if "GMX_LARGEFILES:INTERNAL=1" means that the it is OK for large file support in my cluster. If yes, why mdrun still tells to me that the large file offsets are not supported? Is there any way to make it work in my situation. Thanks for the reply.
