I work in fluid dynamics. I have a Windows NT/W95 product that is heavy into number crunching, matrix methods to be exact. Someone mentioned to me that I should investigate tools or functionality available to me via mmx technology that might give me some gains in run times. I have no idea what mmx technology is or what it might give me or even where to look. Is this an API? Can anybody tell me if and where I should be looking or whether this is a dead end.
