[gmx-users] Test-set problem with Gromacs 3.3.3

[janne.hirvi at joensuu.fi]

Dear gmx-users,

I just updated my operating system to Centos 5.1 and Gromacs to  
version 3.3.3 and faced some problems with test-set  
(gmxtest-3.3.2.tgz). I can pass all the double precision tests  
(./gmxtest.pl -double all), but number of single precision tests are  
failed (./gmxtest.pl all). I looked at the files for these tests, and  
noticed that the corresponding tests include Coulombic and LJ 1-4  
interactions, for which the calculated energies are all zero, whereas  
the reference energies are non-zero with values even 1000-2000 kJ/mol.  
Does anyone know reason for such differences?

Thanks for your help,

Janne
