Nobody would deny that DSM is an easier programming model to use for a large class of applications. Most of the overhead/ loss of performance in a DSM system has to do with the cost of the underlying communication mechanism; the fact that DSM systems can almost never come to par with an efficiently written message-passing application in terms of the number/size of messages generated, hurts the performance almost exponentially corresponding to the cost of the underlying messaging - making the DSM system look extremely poor. Having said that, I'd venture that DSM technology can be considered to be waiting for the NUMA communication technology (interconnect + the protocols) to become commodity.
