[gmx-users] Results from different OS

[Taeho Kim]

Thank for your email.
Two machines Mac G4-733 and G4-500 created the results. I am not sure of their math libraries. I think different process cause the different results. I was able to compare "demo" on two Mac G4-500 and G4-533. The results (500MHz  vs 533Mhz) are identical.  
Thanks,

Taeho
