[gmx-users] question about REMD

[Tom]

Hello

I am running REMD of 53 replica. First I want to equilibrate them.

mpirun -np 106 mdrun_mpi -s topol.tpr -v -multidir
REMD[012345678910111213141516171819202122232425262728293031323334353637383940414243444546474849505152]

I always received the error message:
----------------------------------------------------------------------------------------
Program mdrun_mpi, VERSION 4.6.5
Source code file:
/auto/rcf-proj2/mw1/wangmeng/gromacs-4.6.5/src/gmxlib/main.c, line: 423

Fatal error:
The number of nodes (106) is not a multiple of the number of simulations
(10)
For more information and tips for troubleshooting, please check the GROMACS
website at http://www.gromacs.org/Documentation/Errors
-------------------------------------------------------

Any one know how to remove this limitation of 10 runs?
Thanks!

Thomas
