[gmx-users] Version error running mdrun

[Jordi Camps]

Hello,

I just compiled FFTW and GROMACS from scratch on a system like:
	-PPC970 (G5)
	-Linux
	-MPICH
	-GM (Myrinet)
	-IBM compilers

Now I'm trying to run gmxdemo and the benchmarcks but keep obtaining a very
strange complaint bout the version of the files used. Mdrun say that the
*.tpr files are of a version of gromacs older than 2.0, but I just generated
this files with my own compiled version of grompp V.3.2.1. And if I execute
a "strings topol.tpr | head -1" I get the next string: "VERSION 3.2.1". It
seems that the file has the correct extension.

I compiled mdrun with MPI support, so I must execute mdrun with mpirun.

The log of the mdrun (using only one processor) is this:

NNODES=1, MYRANK=0, HOSTNAME=s41c3b12-gigabit1.mn

Back Off! I just backed up md.log to ./#md.log.1#
Fatal error: Can not read file topol.tpr,
             this file is from a Gromacs version which is older than 2.0
             Make a new one with grompp or use a gro or pdb file, if
possible

Thanks for your help and advises :-)
