Which flags should I use?
AMD Single processor rig: -advmethods -forceSSE -verbosity 9
Intel Single processor rig: -advmethods -forceasm -verbosity 9
AMD Multiprocessor rig: -local -advmethods -forceSSE -verbosity 9
Intel MP/HT rig: -local -advmethods -forceasm -verbosity 9

-advmethods: "Request to be assigned any new Cores or work units." In effect, you get single gromacs 95% of the time. You will still get the occasional Tinker.

-forceSSE: "On machines with an AMD processor, Core_78 gives priority to 3DNow over SSE -- this overrides that." NOTE: AMD TBird processors do NOT support SSE.

-forceasm: "Instruct the core to use SSE/3DNow assembly instructions if possible, even if it has previously made the determination that the machine may not be handling this well."

-verbosity 9: Sets the level of output detail that is written to the log file

Maybe test -local on a single processor , who know that's faster.

-verbosity 9 is not really needed

-local tag is only needed when running mutiple clients, so that the client does not go looking in the registry
