Slide 7

Slide 7 - 10.05.2015 The difference is in the software... Clusters vs SMPs Use of SMPs Common Access to Shared Resources Processors Memory Storage Devices Running Multiple Applications Running Multiple Instances of the Same Application Running Parallel Applications Use of Clusters Common Access to Shared Resources Processors Distributed Memory Storage Devices Running Multiple Applications Running Multiple Instances of the Same Application Running Parallel Applications

Slide 8

Slide 8 - 10.05.2015 The difference is in the software... Why SMPs dont scale CPUCPU CPU CPU I/O Memory This is an SMP CPU CPU CPU Memory CPU Memory Cache Coherent Interconnect L-3 Cache This is NOT an SMP... When CPUs cycle at 1GHz and Memory latency is >100nS, 1% Cache Miss implies

Slide 10 - 10.05.2015 The difference is in the software... Clustering makes Mo(o)re Sense Microprocessor Performance Increases 50-60% per Year 1 year lag:1.0 SHV Unit = 1.6 Proprietary Units 2 year lag:1.0 SHV Unit = 2.6 Proprietary Units Volume Disadvantage When Volume Doubles, Cost is reduced to 90% 1,000 Proprietary Units vs 1,000,000 SHV units=> Proprietary Unit 3 X more Expensive 2 years lag and 1:100 Volume Disadvantage => 7 X Worse Price/Performance
