different result from different cpu

Dear all,
 
We have recently started to use NAMD to run macromolecular simulations.
NAMD is a powerful and user-friendly software, and we really like it.
 
I have compiled charm++/namd on amd64.
"./build charm++ mpi-linux opteron -no-build-shared" when build charm

I downloaded binary namd "NAMD_2.5_Linux-i686" on my own intel P4 CPU.

But when I run the same program with the same input files on the
different cpus, the results are different.

The attachment file "equil.namd" is input file.
The attachment file "equil_out2.xst" is from intel cpu and
"equil_out2_amd64.xst" is from amd64 when I use 1 cpu.

My system become larger when equilibrate the system on amd64.

Any more files needed?

Any tips would be greatly appreciated!
 
Sincerely,
Xiaoqing
