Samplify Exhibiting at Multi-Core DevCon at DesignWest Mar 27-29, 2012

Samplify will be exhibiting at the Multicore Developers Conference March 26 to 29, 2012 at the McEnery Convention Center in San Jose.

Al Wegener will be giving a talk on March 28 at 3:20 pm on “ME-308: What Happens When Multicore Hits the Memory Wall?” Abstract of his talk follows:

Multicore sockets from Intel, AMD, IBM, and Nvidia do not provide linear application speed-up with increasing core counts. While not all applications parallelize well, a disturbing multicore phenomenon comes down to a fundamental I/O bottleneck. Cores per die scales with Moore’s Law, but interconnect to off-chip DRAM, PCI Express, Ethernet, and disk drives does not. Simply stated: multicore CPUs and GPUs are hitting the memory wall. In this presentation we review recent trends in supercomputing, quantified by 10% or less processor utilization, that foreshadow impending multicore I/O bottlenecks. We then present various architectural improvements, such as Map/Reduce, improved DMA hardware, and flexible compression, that together can forge an assault on the multicore memory wall
