They are relevant. More parallel machines are getting more and more popular. So far people haven't complained about Linux's scalability, most probably since the applications they were using were scaling almost perfectly. This is changing. Also there is a lower limit for optimizing the r/w path given by the hardware. As low as it may be - on highly parallel machines it's some kind of wall we will run into that wall and we need to get around it.
