Im working with membrane-peptide simulations of ~30,000 atoms. The box features are 2 quad-core processors 2.00 GHz, 2x6MB Cache L2 and 1333 MHz FSB. As I said, I read an E. Lindahls presentation from Gromacs Workshop 2007 Talks. That says Gromacs normally uses 256MB to 1GB per process, depending on the system, so I believe 4GB are enough for my purposes. At same time, Lindahl says 8GB is recommended to dual quad-core.... The real problem is the cost to duplicate the amount of memory. However, Im gonna pay (literally) to see! :) Thanx Mark.
