Hi netters

Does anybody know if Gaussian for Mac OS X allows running several jobs 
simultaneously?
It is possible to send the jobs from a remote computer?

Thanks

dear ccl'ers,

could someone explain to me how the isotropic and nonisotropic pressure 
scaling in molecular dynamics work?

can i make big mistake if i use isotropic scaling (nonisotropic is not 
yet supported by pmemd) for non-isotropic system (solid-liquid interface)?

thanks for your help. regards,
lubos

It is an issue for liquid:liquid interfaces; see

COMPUTER-SIMULATION OF LIQUID/LIQUID INTERFACES. 1. THEORY AND
APPLICATION TO OCTANE/WATER
ZHANG YH, FELLER SE, BROOKS BR, PASTOR RW
J CHEM PHYS 103 (23): 10252-10266 DEC 15 1995

See the discussions of NPAT and NPgammaT ensembles in the above
reference.  If there's a surface tension, it could be an issue for a
solid:liquid interface as well, but it may depend on details of the
solid phase model.
