Stephen Swoyer at TDWI writes about "Tech Talk: Big Data Meets Big Density".  In this article, he talks about the different architectures used to scale data warehouse systems – SMP, MMP, NUMA, etc.  Stephen talks about how more cores are squeezed into today's chips and how companies like Kognitio are leveraging this to handle even bigger datasets with their data warehouse systems.  In this world of "Big Data", it is important to understand how these data warehouse systems will scale to handle the larger datasets and workloads required in modern data warehouse systems.
