The market for computer memory is entering a period of punctuated evolution as a result of several forces, including the continued growth of mobile devices like smartphones and tablets, as well as growth in the cloud data centers and communication networks that serve data to mobile users. HPC workloads also play a part in the changing memory landscape.

The energy consumption, data volume and velocity requirements are giving way to new, more efficient and higher bandwidth approaches, including Volta, which was revealed during the keynote event.

For the past 8 years, multicore microprocessors have been creating a performance discontinuity, the so-called memory wall. It’s now fairly clear that this widening gap between compute and memory performance will not be solved with conventional DRAM products. But there is one technology under development that aims to close that gap, and its first use case will likely be in the ethereal realm of supercomputing.

Dr. Byungse So, who heads the Memory Product Planning & Application Engineering team at Samsung, shares his thoughts about the memory technologies needed by performance-minded users today and what might come next.

With all the focus on more powerful microprocessors, sometimes it’s easy to forget that speedier chips do no good if memory is your bottleneck. In the final ISC’11 keynote of the week, Micron Technology VP Dean Klein talked about technologies that can help to alleviate this problem. HPCwire asked Klein to preview the topic and give us his take on where he thinks memory technologies are heading, especially in regard to high performance computing.
