Geek Day 0.9 – Update 1
by Michael Hay on Jun 15, 2010
Just gave my short talk titled “Scale-up/Scale/out.” Started the discussion on where the HPC world was 8 years ago: scale out only architectures ruled until the NEC Earth simulator changed the game reminding people about scaling in multiple dimensions. I further tied that into how Hitachi is attacking three dimensions of scaling: up, deep/virtual, and out. For Hitachi scaling up is about incremental adds of cache, ports, processors and capacity, scaling deep is about UVM and addressing external storage, and scaling out is about HAM and UVM. So today we are addressing the 3 dimensions of scaling, which were lessons learned 8 years ago from the HPC space.
I also made a point of mentioning extended copy which originally came out on the 9980V and connected the 9500 to the 9980V for copy use cases as a degenerate form of virtualization that preceded the release of the USP with UVM…
